Dead laptop battery repair

[twi_x]

Hi,

does anyone know how can I repair dead laptop battery without opening and damaging. More precisely can anyone explain me which tool and software is used to flash her (EEPROM) memory ?

The only way to "Repair" a battery is to replace the cell(s). That is basically buying a new battery, so usually that is the more economical (and vastly safer) option.

If it is an older model with 18650 cells (the round ones), they are somewhat easier to deal with. It is very risky to deal with prismatic cells (pouches). They are easy to pierce and will catch on fire. Cells in a battery are typically soldered together with precision temperature to avoid damaging the cells. If you don't already have a basic soldering iron and experience in such matters you will be spending more on the equipment than a new battery will cost.

Options without opening the battery. Most laptop batteries have a reset capacity mode that can be accessed by disabling all power features on the laptop and running the battery until truly dead (most computers will shut off well before this point to protect the battery). Then recharging it. This resets the zero point on the battery and can increase the number of remaining charging cycles and/or usable capacity.

And if cell replacement needs to be reset EEPROM memory .
