I have an LG E500, whose battery was at 63% of capacity (100% 4800mAh), so I decided to had it replaced. So I purchased six 4200mAh cells instead of 2400mAh cells, cracked open the battery, replaced the cells, checked the voltage and cell-to-cell connection, assembled the battery again and inserted into the battery socket. Needless to say, it did not work, as the EEPROM holds data regarding the capacity of the battery regarding the last charge and the design charge. Those values need to be zeroed and updated. I've browsed the web for tools for that purpose and came across some commercial tools that are $150~200 dollars (I can get a nine cell battery for less than that), but not a free tool. From the information I gathered, there's two ways to do it.

This fix should also work with official Sony Batteries too! This process can be divided in two parts: cells replacement and fixing the Recently the battery in my aging laptop (Sony Vaio VGN-NR498E) took a nose dive Battery eeprom works crack. 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.

Get some software that writes to EEPROMS or work my way with I2C until I get the results, which may well compromise other EEPROMS (that I have no knowledge of) in my computer. Some read commands map to write commands in different EEPROMS. Take the battery chip and connect it to an EEPROM system, which is available at work, but I don't know how to do it or what to do with it.

If anyone has experience in handling battery EEPROM rewrite, any help given would be most appreciated. Not easy to manage battery EEPROM reset. It depends of many factor and involves reverse engine the EEPROM data. To read data you need to open the battery, remove the EEPROM and read it with apposite hardware device ( you could use also arduino But at this point you will have to to undestand the data and correct it. Probably would be a good idea dump the data when the battery is new and the use this data when it loose capacity. This is problem is part of our 'capitalist' system: factory want to produce produce and sell sell, this is how our economy works, so they produce stuff with this kind of tricks.

If you open the battery and remove the eeprom you can manually charge the battery. Another 'solution' is to remove the cell and use it for other purpose as e-bicicle.

Battery EEPROM Works is a System Utilities software developed by Rafos International Engineering Lab. After our trial and test, the software is proved to be official, secure and free.

Here is the official description for Battery EEPROM Works: BSEditor: 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. 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 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 you can now.
