I have three batteries for Panasonic cameras. Two fit the G1 and GF1 cameras. Genuine Panasonic 1250 mah batteries, neither one was charged more than twice. New are 40.00, asking $20.00 per battery paypaled and shipped.

A Chinese copy for the new Panasonic G3 i once had, charged once and used to be sure the camera saw this, which it did. Asking 10.00 paypaled and shipped.
Last item is a Travel charger for 120Vplug and also has the car adapter to plug into it to charge the original G1, GF1 batteries. Asking $20.00 paypaled and shipped.
PM or emails work.
