I bought this battery as a backup for my trip to Japan in April. I took 2500 photos and HD movies over a 12 day period. I decided to alternate batteries each day between the original battery and the Lenmar DLP006 and did not notice any difference between the two. The Lenmar held its own as far as power and charge time. I would purchase another one in the future.The battery was used with the Panasonic Lumix FZ35 camera.
