Panasonic Digital Cameras now include a technology that can identify Panasonic's authorised batteries.
For the protection of our customers Panasonic developed this technology after it was discovered that some aftermarket 3rd 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.
Accordingly, for our customers safety, Panasonic's Digital camera firmware have been updated to ensure the genuine battery identification to prevent any unauthorized battery usage for our customers' update at our support webpage, and introduced into each camera's mass-production on running change basis.
Please find the link below to download each camera's updated firmware.
[ Warning ]
After this firmware update your Panasonic Digital Camera cannot be operated by unauthorised 3rd party batteries.
(Currently there is no authorised 3rd party battery available in the market.)
