How to charge!!!!!!!!!!!!!

the best way to charge the batteries is to take them out and place them in an external battery charger, this will also avoid any damage to the camera directly

then also check to see output MA of the USB adaptor which would generally be very less and takes very long to charge

for example if the batteries are 2200MAh and the output MA of the USB adaptor or for that matter of even an external adaptor is 200MA then it takes roughly 11 hours to completly charge the batteries

cheers
pls rate if this was any help
