Unfortunately, after a certain period of time (from a year to five, depending on operating conditions), the battery of any laptop begins to catastrophically lose capacity. As a result, you can’t even dream about any hours of work: if you manage to read the text within half an hour, then this is already good. It would seem that a laptop battery recovery program is not needed. After all, what prevents you from using the obvious solution that lies on the surface - to replace the battery? The answer is simple, just like the question itself: the high cost of an energy source for a laptop interferes. The user who managed to find a new battery for his model at a price less than a third of the entire portable computer can be considered lucky. The result is predictable: if a laptop is used only at home as a replacement for a personal computer,then they work with it only from the network “to better times” (usually to moral obsolescence), but if mobility is needed, you have to spend a lot of money.

Then, in accordance with the polarity, the light bulb and the power supply are connected to the terminals of the battery pack in parallel (the power supply itself is suitable). This is necessary to raise the voltage level to 1.1 V, otherwise the controller will “reject” the battery. Using superglue, we assemble the case.
Now you need a program for the laptop battery. Its job is to calibrate - the controller determines the minimum and maximum capacitance values, as well as the output of batteries to the nominal level. For example, Imtec Battery Mark.
