Bought this battery for an LG VX8300 cell phone. It had a 1200 mAh battery, thought the 1700 mAh would be better, but it was too fat so the cover couldn't go on. Returned it to the vendor (on his dime) and he sent a 1200 mAh no charge. New battery works fine, vendor (separately reviewed) was great.Advice: RTFM, measure.bobbo
