Problem

To repair laptop battery you have to replace cells and to reset battery EEPROM . Cells replacement is easy and can be made by any technician with a spot welder. But EEPROM fixing is very complicated  and can be made only by  person with special skills and equipment.

Solution

Battery EEPROM Works makes this  easy as 1-2-3. Technician needs just to connect EEPROM chip and to press a button. All other work is made by the software. Laptop battery data will look like a brand new. Full Charge Capacity will reflect real cells capacity. Cycles Count will be set to zero. Manufacturer Date will be changed to current system date. Permanent Failure Flag will be cleared and many other changes will be made too. Battery EEPROM Works supports a lot of laptop batteries of different manufacturers.

Generally the process looks as follow:

1.Connect battery to adapter.
2. Read battery data (Read battery data button)
3. Read chip (press Read chip button)
4.Reset chip (Reset (Calibrate) button)
