With the GF-1 body ver 1.2 firmware update Panasonic noted that use of OME BLB13PP battery is required. Looking for a charger without a cord similar to the OME charger that came with the old LX-2. Flip out plug. A few choices out there. Output of the chargers is not the same as the OME charger. Most don't note any overcharging monitoring system. Has anyone tried a cordless after market chargers? Do most users really like & need a ~2 meter long charger cord?
