I have a Kodak Z650 digital camera and an Easy Share printing dock. The camera takes a NiMH 2 battery pack. I have been unable to find the Kodak 2 pack anywhere. I have tried using 2 Rayovac Nimh rechargeable batteries and a Duracell 2 pack NiMH rechargeable batteries. While both of these work fine in the camera when I put the camera on printing dock these batteries do not recharge. Why Rayovac batteries are not recharging when I put the camera on printing dock? I would appreciate your opinion regarding this. Thanks.
