Instructions

If the batteries were, for example, in a digital camera and at some point a signal appeared on the indicator that they were low, take them out and check for residual voltage. It may be zero. You can't do anything with these batteries. But if your device detects a voltage that can be up to 50% of the voltage of a fresh cell, you can try to recharge the battery.

To recharge, use a standard battery charger of the appropriate form factor. Recharging must be carried out by hand monitoring the temperature of the battery and the charger body. The battery may be warm to the touch, but should not get too hot. Recharging should not last more than two hours.

It must be remembered that batteries are so-called dry batteries. Boiling of the electrolyte in them, which is in a viscous state, can lead to swelling of the element and even its rupture. Therefore, you recharge at your own peril and risk. This can be done repeatedly, but each time the element’s capacity will drop by about half. Therefore, it is not advisable to charge it more than twice.

An important condition for the regeneration of dry elements is their discharge during operation. It is also important to remember that a completely dry battery will not be recharged. Therefore, the battery will last longer if it is stored and operated at temperatures from +10 to +30°C or at temperatures corresponding to the rated value.

Sometimes you can crimp the body with pliers or deform it in some other way. This helps because the oxide layer near the negative electrode is broken. But such a deformed battery may not fit into the device container intended for it. It may also cause the electrolyte and device to leak. This method was very effective for the batteries that powered Soviet flashlights and tape recorders. Batteries were not always available to buy back then, and the containers for these devices were very large.

note

Alcoline batteries with the LR marking in their name are the best to regenerate. Cheap 1.2 V batteries often have a negative electrode made in the form of a paper base coated with metal. These batteries are truly disposable, and you don’t even have to try to revive them.

Some batteries have what is called an “activated” negative electrode. That is, before assembly, the surface of this electrode is treated with mercury. Charging such batteries can be harmful to health due to mercury vapor released into the air when heated. If the battery case is marked that it does not contain mercury, then it can be recharged. In the absence of such markings, it is better to refrain from experiments.

Helpful advice

If the battery fails due to the electrolyte drying out, you can make a puncture in its upper part and inject a solution of table salt into it. This restores the electrolyte. But this method is very labor-intensive.

If the battery stops working in extreme cold, this does not mean that it is discharged. It can start working again if it gets warm.

If your phone's battery has been draining very quickly for some time now, it is better to buy a new battery. The battery can drain quickly for various reasons. First of all, if it has been used for several years and has “served its useful life.” Secondly, its operating time is also affected if the phone sank in water. In addition, Chinese batteries have a limited service life. So how can you avoid being left without communication at the wrong time?

The next thing you can do is turn off the backlight on the phone keys, especially if you are usually at home at night.

You can also increase battery life by lowering the screen brightness to a level that suits your needs.

Turn off all sound and light reminders on your phone.

Go to your phone's settings menu and turn on power saving mode. This action will disable many non-essential functions. For example, the period of time after which it will automatically “go out” will be reduced. For this purpose, 10 seconds of downtime is quite enough. By the way, most mobile models have a function that allows you to set this parameter manually.

If possible, set the processor frequency to “normal” mode.

Bluetooth and Wi-Fi wireless interfaces are also powerful consumers of phone battery. Therefore, to increase battery life, it is better to disable both interfaces. It is advisable to include them only if really necessary.

If there is no particular need to save data on external memory cards, remove them from the phone and use its internal memory. Frequently used data exchange with external memory cards greatly increases the battery consumption of the phone.

If you recharge the battery frequently and briefly, it may have a memory effect and the battery will no longer gain its full charge. To eliminate this unwanted effect, completely discharge it twice and then fully charge it.

If the battery has not been used for a long time or is new, then keep its first charge after inactivity for 14 hours, not taking into account the indicator, but not longer than one day.

And, of course, do not use your mobile phone at temperatures above +60 C and below –20 C, as this will not have the best effect on the phone’s battery charge.

A laptop battery is a very important part of a personal computer. In order for it to last a long time and its operation to remain stable, it is necessary to follow certain rules for the operation of this battery.

Instructions

Given the fact that laptop batteries use lithium ions (Lion symbol), it is necessary to carry out several cycles of fully charging and discharging the battery. Turn off the laptop, connect power to it. Wait until the battery is fully charged. Turn off the power and turn on the laptop. Allow the battery to drain completely. Repeat the described cycle 2-3 times.

The battery is now ready for use. If you use your laptop at home quite often, and you have the opportunity to connect it to AC power, then remove the battery for this period. This will help you avoid wasting battery life.

To properly store the battery outside the laptop, it is recommended to follow some rules. Before removing the battery, charge it 50-60%. Wrap the battery in a plastic bag and put it in a cool, dark room. Never expose to direct sunlight. Avoid places with high humidity.

To avoid problems with finding a suitable battery if the first one is damaged, purchase a second battery in advance. This will save you some time and money. The fact is that while this laptop model is quite popular, you can easily find a cheap battery for it. By the way, there is an opinion that the service life of such batteries is much higher than those that come with the laptop.

• how to extend battery life

A mobile phone is an unpretentious device, when using it you regularly need to do only two things: pay for communication services and charge the battery. The batteries in the vast majority of cases are lithium-ion, with the inscription Li-ion on the case. To maximize the life of such a battery, charge it correctly.

You will need

• - Charger;
• - working electrical socket 220 V.

Instructions

Power the battery from the mains using the charger, which is usually included when you sell your mobile phone. To do this, connect the device connector to the cell phone connector. After this, insert the electrical plug into a working socket with a voltage of 220 V.

Do not charge your cell phone battery near heating appliances or other local heat sources. The temperature range at which the device “feels” normal is 19-35 degrees Celsius.

If you brought a mobile phone from the street in winter, do not immediately charge it. Wait 30-40 minutes for the battery to warm up to room temperature. With strong cooling, it is advisable to wait 1-1.5 hours.

While using your mobile phone, monitor the battery charge level using a special icon on the display. Don't wait until the battery is completely depleted. Use this rule: as soon as the charge level is less than half, connect the battery to the network. This will extend the life of the device.

Once every two to three months, allow the battery to drain completely. This is necessary to debug the operation of the microcircuit that monitors the battery status.

Do not leave your phone on charge overnight or while you are away from home for a long time. Cases of device fire cannot be ruled out. Even if you see that the battery has not yet been charged, you can safely disconnect it from the network; this will not cause any harm to the device.

note

A computer USB cable, a car charger, ordinary batteries connected according to a special circuit, special devices from the already familiar “frog” to such technical innovations as a pen-charger can also be used as a power source for the battery.

Helpful advice

Typically the battery lasts for 300-400 charging cycles. If you purchase a device for future use and start using it after long-term storage, be prepared for the fact that its capacity may be less than usual.

Tip 5: How to increase the battery life of your mobile device

Instructions

Reduce screen brightness.

The auto-brightness feature found on most phones automatically adjusts the screen brightness based on ambient lighting conditions and system operations. But manually, you can reduce the screen brightness even further.
Set the screen timeout. Some devices have special buttons to turn off the screen, while others allow you to programmatically configure settings to lock or turn off the display. If possible, make sure the screen turns off automatically after a minute of inactivity.

Turn off Wi-Fi.

If you are not using a Wi-Fi connection, turn it off. The same applies to Bluetooth.

Disable or limit notifications.

iOS users will have to manually do this for each app. Go to "Settings-Notifications", touch each application you want to configure and set the Notification Center switch to Off. If you are an Android user, disable synchronization of unused services. To do this, go to the "Accounts" section of the "Settings" menu and turn off synchronization for all services that are not used.

Minimize the impact of applications and settings that are not currently needed.

To unload apps from iOS, double-tap the Home button. Once the multitasking tray appears on the screen, hold the application icon until the X button appears. Tap it to close the application. Windows Phon 8 users can use the popular Battery Saver feature to limit application power consumption.

Turn on airplane mode.

This mode disables all wireless interfaces of the device, including cellular communications, Wi-Fi, Bluetooth, GPS and other location services.

Turn off location services.

This measure will save you a lot of energy and some money on trips abroad.

Turn off vibration alert.

A vibration alert requires much more serious energy expenditure than a sound signal. If you're in a location where you can't disturb others with loud noises, consider temporarily turning off all notification sounds.

Don't let your device get too hot or cold.

Safe temperature conditions for electronic devices range from 0 to 35 C. Take the necessary measures to protect your phone from temperature extremes.

Technological progress does not stand still. Nowadays, what seemed like an unattainable dream just yesterday is now becoming an everyday thing.

Just recently, engineers at Boston University defended a patent for technology using special flexible photovoltaic fibers that can independently produce electricity. The innovation will be able to receive electrical impulses from the fibers of an ordinary carpet when a physical impact of a certain power is exerted on them.
For example, a specially optimized carpet with a canvas size of 20 by 20 cm will produce 1 watt of energy when walked on. For comparison, one iPhone needs 5.5 Wh to fully charge its battery.
As you know, the piles of an unusual carpet are hybrids of two materials: photovoltaic, which receives energy from the sun, and piezoelectric, which generates electricity when walking. According to the head of the study, this innovative fiber was specifically created to replace alternative sources of electricity such as wind, water and sunlight.
Naturally, a lot of time will have to pass before the invention becomes firmly established in our lives, but it can already be predicted that with the advent of such carpets, previous chargers will sink into oblivion.

Tip 7: How to extend the battery life of your phone or tablet without a power outlet while traveling

The constant companion of the modern tourist is a mobile assistant in the form of a smartphone or tablet. Indeed, electronic maps are much more convenient and informative than paper ones. They know how to create routes and update themselves. We have an almost perfect navigation device in our hands, but it has one big drawback. It needs to be fed from an outlet from time to time. Here are three tips to help your smartphone or tablet stay truly mobile for longer.

Instructions

Make sure that all wireless interfaces are turned on only when really needed. For example, when Wi-Fi is turned on, it continues to scan the network and waste the battery of your mobile device even when you are not on the Internet. The same can be said about Bluetooth. By turning them off regularly or even putting your smartphone in airplane mode, you can extend its battery life by an hour or two.

Before you go on a long trip, consider purchasing an external battery for your mobile companion. They differ in capacity. Higher capacity means more expensive device, but also more energy for your smartphone. This external battery can give you up to 8 hours of mobile work.

Well, as an option for real travelers - a bag or backpack with solar panels. This accessory has a built-in battery. During the day's journey, he will accumulate enough energy to chat with friends on a social network or simply surf the Internet before going to bed. Those. it allows you to power your mobile device even when there is no sun. This is the most effective way to increase mobility, as it makes you completely independent from an outlet for many weeks.

Helpful advice

When choosing an external battery, pay attention to its capacity. If you are buying it for a smartphone, then you can limit yourself to entry-level models, preferably from 4,000 to 8,000 mAh. And the tablet will require a more powerful external battery. It's better to think about the 12,000 to 16,000 mAh version, but they will be heavier.

Tip 8: How to keep your phone in good condition for as long as possible

Many people want to keep their phone in excellent condition as when it was purchased. Various scratches, chips and cracks can make the phone so unattractive that it would be a shame to even put it on the table. Such a phone will be very difficult to sell if necessary. And besides, a smartphone in good condition will serve its owner much longer.

You will need

• - case;
• - special napkins for glass.

Instructions

Keep your phone in a case. For many modern smartphones, as an addition, you can purchase a special book case that is attached to the phone instead of the back panel. Cases will help prevent moisture, dust and dirt from getting on the phone, and can also provide additional protection if the phone is dropped. A huge range of covers will satisfy every customer's taste.

When you take your phone on the road, put it in a separate pocket. If you put your smartphone in a pocket where there are change, keys or various key fobs, they can cause scratches on the phone panel. In some cases, metal objects located nearby can not only scratch, but also create a crack on the mobile screen.

Have special glass cleaning wipes on hand. If necessary, wipe your phone with them. If there is dust on your smartphone, it is better to remove it with this napkin. When trying to remove dust particles by hand, you can create pressure and make micro-scratches, as well as leave lint on the screen. Microfiber does not leave marks on the mobile phone.

Do not attach metal key fobs to the phone; they may scratch the phone panels. If you really want to buy some jewelry for your device, it’s better to buy a keychain with a soft pad. If necessary, it can be used to wipe the phone, or place the phone on this pad.

Don't place your phone face down on a table. It is better to place a napkin, a piece of cloth, or, in extreme cases, a piece of paper under the phone. If you do not listen to this rule, then when the phone comes into contact with the table, scratches may appear due to the unsmooth surface of the table.

Rings with different inserts can also scratch your smartphone, so it is better to take it with the hand that has fewer rings on. Precious stones, especially diamonds, can easily scratch your phone screen.

Tip 9: How to make your smartphone work longer without recharging

Most smartphone owners dream of having sockets everywhere - in minibuses, in tree parks, and in grocery carts in supermarkets. All this is because the battery charge tends to run out at the most inopportune moment. However, by following a number of rules, you can make your smartphone work longer without recharging.

Vibration when making a call consumes a lot of energy. Many people have it turned on all the time, but often there is no need for it. The vibration alert was invented to notify you of calls and incoming messages in cases where you need to turn off the sound - in theaters and cinemas, at meetings, etc. In addition, many users always have essentially useless vibration turned on when they press the keyboard.

Quit the habit of constantly checking social media feeds. Admit it, you often do this out of inertia, scrolling through the same posts and photos several times. There are no miracles here: if you don’t get out of the mobile Internet, the battery will run out quickly.

If your battery is draining faster than before, the problem may be with the battery. Over time, it “wears out” and begins to work worse. In this case, only replacing the battery will help. If the battery is removable, it is very easy to do this yourself, and instead of throwing away the old battery, you can carry it with you and use it as a spare.

We are accustomed to charging gadgets when the battery is almost completely discharged, but this habit has continued after the recommendations of the manufacturers of nickel-cadmium batteries. For modern batteries it is not entirely true. Yes, you can wait until your smartphone or tablet turns off and then put it on charge, but this is absolutely not necessary.

Those batteries that are installed in modern tablets, smartphones, and laptops can be charged until the device turns off spontaneously, and it is not at all necessary to bring the charge level to 100 percent. The charging mode can be close to the most comfortable for the device owner - if it seems to you that there is not enough charge for the tasks at hand, do not worry about the quality of the battery, just let the gadget recharge to the level you need. Electronics manufacturers advise charging batteries whenever possible and not chasing the ideal 100 percent.

But you shouldn’t leave the device longer than necessary. Modern smartphones and other devices usually take no more than 4 hours to fully charge, so you shouldn't leave them on charge all night.

It is very important to monitor the temperature conditions in which the gadget is located. Do not allow the device to become significantly overheated or too cold. In summer, do not leave the tablet in the sun for a long time; in winter, carry it in an internal pocket or a thick case. Do not forget also that laptops cannot be placed on soft surfaces (blanket, sofa, pillow) so that the ventilation system can work fully.

Helpful tip: About once every month or two, give your device a chance to completely discharge and charge. This “training” of the battery allows the system to correctly determine the device’s charge level.

But here is the device in your hands. For long battery life, do not ignore the rules for maintaining and charging it. Discharge it at least once a month and do not keep it on charge for too long.

Once you have started using your smartphone regularly, consider the following:

• Adjust the screen brightness to minimum, this will greatly increase the battery life of your smartphone. It is also worth setting the minimum waiting time for the standby mode (the screen should go dark after about 5 seconds of user inactivity).
• Do not multitask your device (close all programs that you are running and are not currently using).
• Check? what services and applications start when the device is turned on. Disable everything you don't need in the system settings.
• Make sure that in those moments when you are not using the Internet, Wi-Fi is turned off, as is Bluetooth.

If you do everything as described above, but you continue to lack the battery capacity of your smartphone, you should think about buying an external battery.

With bright screens require a lot of battery power.

But besides the screen, various applications can consume battery energy.

What needs to be done so that the phone does not discharge quickly and its battery lasts as long as possible?

First you need to answer the question: "How do smartphone batteries work?".

Most smartphones have either lithium-ion (Li-ion) battery, or lithium polymer battery (Li-pol), and such batteries do not need to be fully charged and discharged at the very beginning of using the smartphone.

But such batteries can suffer from low voltage problems, so it's best to charge partially (between 20% and 90%) rather than completely charging and discharging.

There is still debate about caring for these batteries, the key is to find what is best for you.

How to increase battery life

Here are some tips on how to make your smartphone battery last longer and not drain quickly:

1. Screensaver and themes in dark colors.

If your device has an AMOLED screen (like most Samsung devices), use dark colors for the screen - this will help save battery power, because AMOLED screens only illuminate colored pixels. Black pixels are not backlit, which means the more of them you have, the more energy you save.

2. Don't use automatic brightness.

This feature may seem useful, but automatic brightness usually makes the screen much brighter than it actually needs to be. It's best to set the screen brightness manually and change it whenever you need to. This is a very important point, because... The screen is a major waste of battery power.

3. Set sleep mode (screen timeout) for the shortest possible time.

Just think, if your screen automatically turns off after 1 minute, it will use 4 times more power than if that indicator stays on for 15 seconds.

Studies have shown that the average user turns on their smartphone 150 times a day, which means everything possible can be done to reduce screen time.

4. You should not use unnecessary functions, such as animation or smart scrolling, because... they also use up your battery power.

Long battery

5. Turn off vibration.

It's also worth turning off the phone from vibrating when you press keys - this may seem like an interesting feature, but it's useless and only drains your battery. Of course, if you simply need this function, then you can skip this item. It takes more energy to vibrate your phone than to make a simple ringing call.

6. Use notifications for your lock screen.

A lock screen can help save your battery power. And all because you see all notifications at once, without having to turn on the entire screen. This screen comes by default on all smartphones with the Android Lollipop operating system.

If you have Android KitKat (previous version), try using widgets for your lock screen if your RAM supports it or you can install an app that does it for you, like Dynamic Notifications.

You will still have to turn on the screen, but it will be on for much less time than usual. In addition, the screen will be dark, which will also save battery power.

7. Set the "Do Not Disturb" function.

This function allows you to activate silent mode, and the user will be notified of all notifications when the phone vibrates.

This utility also disables Wi-Fi and mobile Internet. When you're at work and don't want to be disturbed, set a mode where your phone won't ring or vibrate.

You can also turn on airplane mode when you decide to take a break.

When you install apps like Greenify, the apps you normally run on your phone regularly will shut down and go into "sleep mode" when you're not using them.

Extending the life of your smartphone battery

8. You don't need to be connected to networks 24 hours a day.

Turn off GPS, Bluetooth, Wi-Fi and mobile data when you don't need them. To clarify your location and navigation, you can use either Wi-Fi or 3G, or GPS, but not all together.

9. Try to limit the use of widgets, especially those that require an Internet connection.

Widgets that show the weather, as well as widgets for Twitter, Gmail and some social networks. networks need constant updating, which means they need energy.

It's better to simply turn on a particular widget when you need it, rather than leaving it to run and update on its own.

Almost every person who has bought a mobile phone at least once in their life has been told by a salon consultant that the mobile phone must be completely discharged immediately after purchase, and only then put on charge. You can find out why this is necessary and how to do it by reading this article.

This procedure is mandatory.

The process of “pumping” a mobile phone is when it is completely discharged and then fully charged.

Each rechargeable battery has a memory, let’s say it is discharged by 40 percent, and after you put it on charge, it charges your battery to the remaining 40 percent, and when discharged during use, the battery will again discharge to this level and require it to be charged again. Accordingly, if you discharge and charge the battery completely, it will take longer to discharge.

The rhythm of our lives obliges a person to be constantly in touch due to various kinds of circumstances. That is why it is very important to always have a working phone with a good battery at hand. You can find complete information about phones and their technical characteristics on the website m.ua/kata/50/. There you can order the phone or accessory you are interested in or get advice from a specialist.

Stages of rocking a battery

1. Immediately after purchase, you must completely discharge the battery. You can play games or listen to music, it is important that the phone is completely discharged;
2. After the phone has completely lost all battery energy, it must be charged for 12 hours, no less. Do not disconnect the power from the network, even if the phone notifies you that it is fully charged;
3. Some experts recommend performing this procedure 3 times. When working with a phone at the stage of “pumping” it, never put it on recharge. Also, when charging for 12 hours, do not unplug it from the mains under any circumstances.

Of course, during this procedure, yours will be tied to its charging location for some time. You may not be able to use it fully at this time, but after you complete all the necessary instructions, you will receive a battery that will work at full capacity. A “pumped” battery will hold its charge for the longest possible time, and the service life of this battery will be much longer.

Modern batteries installed in our mobile devices are very durable and designed for a long service life. In order to make the service life as long and safe as possible, be sure to adopt and follow the following simple recommendations:

1. Once a month, without fail, completely discharge and charge the device’s battery. This procedure is called calibration. Although modern Li-ion batteries are practically not subject to the “memory effect”, such an operation is simply necessary for their long service life!

2. Try not to allow the device to run on low battery power. The fact is that each battery has its own safe voltage limit (about 3V), operating at which can lead to damage to the cells. That's why Place the device on charge when 15-20% charge remains.

3. To avoid trouble, never store the device with a completely discharged battery.

If you are not going to use it for a long time, then make sure that the battery has at least a small charge. Before using your device again, fully charge its battery.

4. Avoid frequent full discharge of the device's battery! Complete discharge of the battery is only necessary before starting operation to calibrate the control system. Forcibly turning off the phone does not affect the battery life for the better. Don't be afraid of “unplanned” exercises. Do them more often.

5. Do not overcharge the battery. Those. in other words, don't leave your device charging all night. This reduces battery life.

6. If possible, observe the temperature conditions when charging and working with the device. Avoid high (above 35 C) and low (below 0 C) temperatures. Operating the battery in an unfavorable range will accelerate its wear and tear. The optimal temperature for operation and charging will be room temperature (21 - 22 C). The worst option here is to work with a fully charged battery at elevated temperatures and in direct sunlight. In this case, the temperature inside the device increases significantly, which does not have the best effect on all its elements, incl. Battery

7. Before charging, remove all cases from your device. They interfere with its natural ventilation, which increases the risk of malfunctions.

8. When charging the device, if possible, turn off WiFi, various services, cellular data, push, in general, everything that actively loads your battery. In this case, charging will be faster, and heat generation, with all that it entails, will be less.

Today's video is dedicated to interesting ways to extend the life of a dead battery. What to do if they shrank and you need to restore them so that they last for some more time. The proposed method is not new, but it will differ from what we are used to seeing and hearing. Told by the author of the channel Homemade and gadget +.

So, our batteries are in a flashlight with a fan. Let's check how they work. It can be seen that the flashlight is on, the fan rotates with difficulty. Naturally, they sat down. We take out the dead batteries of this device and check it with a tester. Now let's leave them in a pre-prepared container, which will contain a stand so that the batteries are in a vertical position. The stand is made of ordinary plastic couplings.

Place the container with its nose down and up and fill it with water 3-5 mm below the top level of the battery. This is necessary so that there is no short circuit between plus and minus through the water. Fill with water, ordinary water, literally two minutes after it was heated to a boil. Leave in this position for 10-15 minutes until the water cools to room temperature.
The water has cooled down. We take it out and check it with a tester. The device shows that the batteries are almost restored to their original charge.

It can be seen that the flashlight shines brighter than before the service extension, and the fan has also restored its operation.
This method was tested only on alkaline batteries.

Restoring salt batteries

In this video I will share my method of restoring salt AA batteries. To do this, we need the batteries themselves, electrical tape, a marker, scissors, a testing device, a syringe and a working solution. First, let's check for functionality. As you can see, they are generally dead. Let's see what the device shows. We take them out and start restoring their operation.

Important information. Only salt batteries are suitable for this experiment. They must be intact on the outside, there should be no leaks or discharge. Batteries of other types, that is, alkaline, alkaline or rechargeable, are not suitable for this method. This is dangerous to your health.
So, we take a salt battery, find the connecting seam and make 4 marks at an angle of 90 degrees to the seam at a distance of 1 centimeter from the edge. In these places we make holes with a 4-mm drill. We drill very carefully so as not to damage the shell, we drill only the outer shell, no more.

After making holes for the batteries, place them in one container with the plus side on top. Fill with working solution so that the level covers the top drilling. We use 6 percent food grade vinegar as a solution. Fill it out carefully. Leave the batteries in this state for 10-15 minutes. The temperature of the solution should be room temperature. We wait 15 minutes and proceed further. After the batteries have been soaked in the solution, carefully lay them out and place them to dry, seam side down, so that the excess is absorbed onto a napkin. Leave in this state for 10 minutes. Next, cover the hole with regular electrical tape.

The final stage of our charge restoration experiment has arrived. We check with the device. We insert them into the flashlight and try to turn it on. The light is on. The experience was a success. Let me remind you that this method of extending operation is only suitable for salt batteries.
