Panasonic have just released a firmware update for 16 cameras in the digicam range to stop the use of third-party imitation batteries. Which Panasonic says “do not meet the rigid safety standards Panasonic uses”.
Three battery have been affected by the firmware update, DMW-BCF10, DMW-BCG10 and DMW-BLB13. Official Panasonic batteries are available for around $40-50 online, whereas third-party alternatives can be bought from as little as $10.
Panasonic developed this technology after it was discovered that some aftermarket third-party batteries do not meet the rigid safety standards Panasonic uses. Some of these aftermarket batteries are not equipped with internal protective devices to guard against overcharging, internal heating and short circuit. If these aftermarket battery packs were used, it could lead to an accident causing damage to your camera or personal injury” Panasonic
