Panasonic Battery Information
Panasonic has released firmware updates for some of its digital cameras.
When the update is installed in the camera, you will be unable to use any third party batteries in that camera.
You must use a genuine Panasonic battery only.
You have probably heard of laptop batteries catching on fire.
Apparently those same type of faulty batteries are now a hazard for digital cameras.
Most third party batteries are made in China.
