Battery EEPROM Works is designed to simplify the process of laptop battery repair. This process can be divided in  two parts: cells replacement and fixing the content of EEPROM or integrated Flash of laptop battery controller. While cells replacement is easy and can be made by any technician who can work with welding machine, EEPROM fixing is very complicated and  important task and can be made only by the personal with special skills and equipment.

Battery EEPROM Works makes this process as easy as 1-2-3. The technician needs just to connect EEPROM chip to adapter and press the button. All the necessary work will be made by the software. The laptop battery data will look like a brand new: Full Charge Capacity will be the same as you entered and will reflect real cells capacity, Cycles Count will be set to zero, and Manufacturer Date will be changed to current system date, Permanent Failure Flag will be removed and all the additional necessary changes will be made too. Battery EEPROM Works supports a lot of laptop batteries of different manufactures
