Which is it? When I bought the Lenmar CBD366 via Amazon, it arrived in Lenmar packaging and was rated at 600mAh. The label on the CBD366 pictured here shows 700mAh, but the Lenmar site and specifications show 800mAh... The original 3SN-AA80-S-J1 battery was 800mAh. The 600mAh version rapidly discharges (dies) during conversations and soon looses the ability to hold a charge.
