No function with Olympus E-510

Had this battery ordered as a spare battery for my camera twice (Olympus E-510) and loaded with the standard charger for Olympus Li-Ion batteries. However, the camera comes with this battery just not on, both batteries were tried and both the camera and refused every time the service. Exchange the batteries and refund the money as always ran despite slashed packs Amazon problems, which is why I was overall not very disappointed.
By the way: A purchased at the shop original battery works fine.
