Have tried the original Panasonic Lumix LX5 battery of the Leica D-LUX5. After a few failed attempts with cheap batteries, I must say: This works great here, that the battery state is now displayed correctly. Allen Leica D-LUX5 owners can I recommend the Panasonic battery warmly. The price is quite steep, but much cheaper than 69 EUR for the original battery by Leica.
