Use the battery since August in my new Panasonic DMC-FS11 and works perfectly until now! In experiments with an AT battery I wanted to get involved not at first, especially since these often 20, - cost. The capacity is sufficient for about 200 photos. Although is very little at first glance, but has so far always served. The price is quite high, but it is true the performance and reliability the battery. Full 5 stars!
