I'm assuming this camera uses standard AA cell shaped batteries. I've heard complaints of overheating when the batteries are charged in a docked Kodak camera -- which would shorten their life badly.
A battery charger is often sold with packs of NIMH cells or separately for not much money. This might help.
This has been a problem ever since the camera was purchased new. I have a Kodak Z 650 which when the battery is charged in the camera dock sometimes you can get 100 or more pictures out of it & other times you can wait a day or 2 & it will be so dead that it won't even cycle a single time. I've tried new NI-MH batteries twice with no change to this problem, contacted Kodak during the warranty period & they just stalled until the warranty expired then said send it in with $150.00 & they would look at it finally but that the warranty had expired so I would have to pay full price for the repairs, I told them that I had attempted to get service for it from them before the warranty had expired but that they had not wanted to act at that time .
1st has anyone else had this problem & if so haw did you fix it??
2nd how can I get past the layers of denial at Kodak to get them to honor the warranty ??
