for e900 it is good?
The model # e900 is not familiar, but the one I bought is a good one. These smaller batteries can on do so much for your camera. I reccomend
severals if that's your only camera.
Note: ebay purchasing of batteries is not a good idea. too many counterfit batteries here in the states & elsewhere.
If the battery, while charging, gets very hot, too HOT to hold, then maybe the production of the batter had problems and return it.
