It often happens that the battery of your favorite laptop suddenly starts to fail. This is especially true not of the new, but already in the order of the worked equipment. What to do in such a situation? Is it possible to breathe new life into an old electrolyte? Is it possible to repair the battery yourself? Let's not get ahead of ourselves. We will tell you everything in order.
Information is everything
First of all, try to find the maximum information about your battery. Experienced users have noticed that laptop manufacturers often produce a special utility that can calibrate laptop batteries. Of course, such a procedure can last for a whole day, but believe me - the result is worth it. And you can reuse the old battery. At the same time, it will work for a rather long time without a recharge source. In other words, battery repair may simply not be required. If manufacturers can provide such an opportunity, then on the official website you will find and read everything that will concern the proper use of the utility.
Is it possible to do without repairs?
Experienced users are advised to use the utility about 3 times a month. Especially if you like to work on a laptop without connecting to an electrical outlet. By the way, if an electric current is constantly supplied to your device, then it is better to remove the battery when its indicator shows 100% charge. So you can significantly extend the battery life. Do not forget about it. If the manufacturer did not provide a utility, and the usual calibration procedure does not help, then there are several options: either replace the battery or repair the battery yourself. The first option is a simple matter, so we will talk about how to breathe new life into this detail.
Cooking tool
In order to successfully complete all of the operations below, you must have: a tester, a knife, car bulbs with wires connected to them, a 40 W soldering iron, a tester and cyan-acrylic glue. First, we disassemble the battery from the laptop. You have to work with a lithium-ion energy storage device, so try to be extremely careful and accurate. Find the seam among the batteries that are glued into a single whole . Next, disconnect the battery into 2 parts using a breadboard knife. Now you can directly repair the battery. But first make sure that it is completely discharged. Check it out is simple enough. Connect the car bulbs to it. The voltage should be in the following limits: 3.6-4.1 V. After connecting, the lamp should light up. If you saw a different voltage on the sensor, then unsolder the elements from each other and check each of them separately. In case the values are far from the ones given below, such a unit must be replaced. This is problematic because battery cells must be ordered in advance. Next, we reduce the voltage in serviceable units to 3.2 V using our irreplaceable light bulb. If you replaced something while doing the repair of batteries for laptops, then with these elements we do the same. If the voltage drops to too low, it is necessary to connect a 5 W bulb to our circuit and restore the charge level to 3.4 V. Only after this procedure will the electrolyte for the batteries be charged normally. Now with the help of glue we collect the battery, connect it to the laptop and get to work.
