Had my old Olympus certainly no longer used because whenever they took, the battery went on strike. Since I have this lithium battery is one thing of the past. Had ordered 4 pieces of it and the associated charger my year at least 1. I was skeptical at first, because the lithium-ion batteries yes eigendlich still have at least a third or even fourth contact. Thought at first, maybe it is in reality only NiMH cells! But now I'm sure there must be Li-cells. Because they really keep very long time. And if they are sometimes empty, I always got the second pair are ready and shooting can again without end. 200% Kaufempfelung!
