Very good Li-Ion battery, which is enough for about 50 to 60 photos with flash and the monitor on. While this may seem sufficient, but in practice it's a bit annoying, if you recharge the battery already after one day. The Positve is that the battery has no memory effect and is thus, even if it is not completely empty, again can invite him. Otherwise, you really came the next day with the then maybe half full Battery is no longer far.
