It often happens that the battery of your favorite laptop suddenly starts to fail. This is especially true of not new, but already well-working 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 as much information about your battery as possible. Experienced users have noticed that laptop manufacturers often produce a special utility that can calibrate laptop batteries. Of course, such a procedure can take 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 quite a long time without a source of recharging. In other words, battery repair may simply not be required. If manufacturers can provide such an opportunity, then on the official website you will also findread everything related to the correct use of the utility.
Is it possible to do without repair?
Experienced users advise using the utility about 3 times a month. Especially if you like to work on a laptop without being connected to the mains. By the way, if the electric current is constantly supplied to your device, then it is better to remove the battery when its indicator shows 100% charge. This way you can significantly extend the life of your battery. Don't forget about it. If the manufacturer has not provided a utility, and the usual calibration procedure does not help, then in this case there are several options: either replace the battery, or repair the battery yourself. The first option is a simple matter, so we will tell you how to breathe new life into this detail.
Preparing the tool
In order to successfully complete all the operations below, you must have: a tester, a knife, car light bulbs with wires connected to them, a 40 W soldering iron, a tester and cyano-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 glued together. Next, separate 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. Checking this is easy enough. Connect car bulbs to it. The voltage should be within the following limits: 3.6-4.1 V. After connecting, the light should light up. If you see a different voltage on the sensor, then unsolder the elements from each other and check each of them separately. If the values are far from those given below, such a block must be replaced. This is problematic because you need to order battery cells in advance. Next, we reduce the voltage in serviceable blocks to 3.2 V using our irreplaceable light bulb. If you replaced something while you were repairing laptop batteries, then we do the same with these elements. In the event of a voltage drop to too low values, 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, using glue, we assemble the battery, connect it to the laptop and get to work.
