Repair your laptop battery with your own hands. Information needed to repair the battery of laptops

Stationary computers, which were incredibly widespread in their time, are gradually beginning to recede into the background, and modern people are increasingly using specialized portable devices such as netbooks and laptops. However, given the constant movement and conditions for the use of such equipment, it often quite often breaks down various components, and in particular it is necessary to do repair of the laptop battery with their own hands.

When it needs to be repaired?

The main advantage of laptops is that they are mobile, but this advantage completely disappears in the event that for some reason the battery has completely exhausted its resource. Once a mobile device eventually turns into an ordinary stationary computer, which has much smaller characteristics compared to those that a PC with a similar price has. Attempts to find a completely new battery in the majority of cases result in the fact that either such devices are not released at all, or their price is approximately 25-30% of the total cost of the device. Buying with hands is also not the most optimal option, because the battery you bought could already greatly develop its own resource.

It is for this reason that a much more optimal option is to repair the laptop battery with your own hands, because it is not only economical, but also quite a quick solution.

How to prevent possible malfunctions?

To date, very common is the use of specialized nickel-metal hydride batteries, as well as lithium-ion devices, while the latter are most often installed in modern laptops due to the fact that they are more capacious, and they lack the so-called "effect Memory ". But this variant also differs in its drawbacks, and in particular this refers to the vulnerability to high temperatures, deep discharge or too much charging current. At the same time, the capacity decreases significantly over time, and it is almost impossible to try to swing such a battery to the old parameters, even if you are thoroughly versed in how to repair laptop batteries with your own hands.

What does the manufacturer consider?

To ensure a long-lasting battery life, a dedicated microcontroller is used that carefully monitors the voltage and temperature data, eliminates the possibility of recharging or strong discharge. Such microcontrollers use in their work a lot of special algorithms that ensure the long-term operation of various batteries. For example, often such options are supported by Energy Star notebooks, which support the battery charge at 70-85%, not giving the possibility to reach the limit value, and completely turn off the device after it is discharged to a level of 5-9%. That's why the owners of such devices are much less likely to need the information needed to repair the battery of laptops with their own hands.

What should the user account for?

Users should pay attention to the fact that in the process of working with various multimedia applications or demanding games, modern laptops begin to allocate a lot of heat, which adversely affects the battery life. In other words, if you actively develop the resource of your computer, then in that case you may need to repair the laptop battery with your own hands much earlier. HP, for example, produces gaming laptops that have specialized means of protection against such consequences, but in reality they are not able to provide the required result.

The best thing you can do for your own battery using a laptop in standard PC mode is to completely disconnect it and plug it back in if you really need it. In this case, you do not have to often repair the laptop battery with your own hands. "Sony, for example, uses in their laptops specialized batteries, which in case of disconnecting them from the device can last particularly long.

How to store it?

Self-discharge of such a battery is approximately 4-6% each month, but you can reduce this figure if you store the battery in the temperature range from +5 to +8 ^о С, and at the same time provide protection from light, as well as all other heat sources. Thus, you can significantly increase the longevity of your battery, so that it can work for you for up to 10 years without having to regularly repair the laptop battery with your own hands. "Toshiba" has released a number of laptops in due time, in which the batteries even overcame this threshold.

How to repair?

First of all, you need to completely discharge your battery, that is, turn off the power and wait until it is completely discharged. Now you can unplug the battery and start to disassemble it.

At first glance it may seem that this is a monolithic piece of plastic, but in reality it is far from the case. There is a mass of fastening screws, which must be unscrewed and then gently knocked on the device with a hammer on the seam. It should be noted that the hammer should be wrapped in a soft cloth, because otherwise you can split the case, and in this case you can hardly expect that you will benefit from this repair laptop battery with your own hands. Acer often produces laptops with batteries that have a weak case, so it's very important to consider. You can help yourself with a thin screwdriver or a blade of a knife. The main thing is to do everything extremely carefully so as not to damage the electrochemical elements or directly to the controller board itself.

Testing

Now you need a multitestaster, with which you can easily find the element that broke. This is done by means of a standard voltage measurement of all the battery components, since a strong dip in it clearly indicates a malfunction of the cell. Of course, you will immediately have a desire to replace only this element, but in fact this is also not the most optimal solution. With this replacement, you will need to extremely carefully calibrate the charge controller, which is almost impossible to do if you are done at home to repair the laptop battery with your own hands. Asus is especially notable for this feature, so the entire set of elements should be replaced immediately.

Batteries today can be bought in almost any store that sells various computer components. You can also order all these items via the Internet.

Helpful Tips

There are several important things to consider when buying parts in specialized stores:

• All elements must have the same capacity and type, which must completely coincide with the original elements in the disassembled battery. Ideally, you need to buy items from one lot to increase the chance that they will have the same internal characteristics.
• Components must have an extremely close internal resistance. To check it is quite simple - you need to charge each of the elements to a voltage of 3.8, then with each individual element to do the following procedure: connect a load whose resistance is 4 Ohm, and the dissipated power is 10 watts, then measure the voltage. The voltage drop must ultimately be the same for each individual element.
• All installed elements must have the same voltage. Few people know that the majority of the majority of the components sold half-charged, because a deep discharge is disastrous for them, but the battery can only be installed in the case if they were previously discharged to 3.1V.

If you immediately install items directly from the store, there is a possibility that the controller will consider them to be faulty, due to which either they will completely refuse to charge them or charge them incorrectly, which can eventually provoke overheating or even explosion of the battery.

Finishing work

After you replace all batteries, you will need to carefully solder the contacts, as well as the final assembly of the battery in its previous state. The battery should be put on charge, while you yourself have to control this process and do it very carefully. In the event that the battery temperature starts to rise too much, and you start to hear a crack that is not characteristic for normal operation of the device, you should instantly turn off the external power and get the battery out of the computer.

After carrying out such manipulations, you will need to measure the time of the laptop before it is completely discharged. In this case, you will need to understand how quickly the device is discharged during operation, and if this time has grown from several minutes to several hours, you can congratulate yourself, because you have successfully carried out repair of your laptop battery with your own hands. Samsung and some manufacturers often provide users with detailed instructions on how to conduct similar procedures with their own hands, but in any case recommend to contact specialists.
