Usually Olympus cameras have other batteries with longer life in them. You just have to pay more for them.

How are the contacts in your camera? are they bent to the point that they could be losing contact or is there any corriosion or oxidation to them?

It depends on what kind of battery your using. is nickel cadium or is a lithium battery there is a big difference. everything that uses a battery when in operation draws down a battery. is it rechargable? if so it could be your a/c charger is faulty and when charging the battery it's not giving it it's full charge. are you letting it fully go dead and then recharging? or are you recharging it constantly? these could be a few reasons other than the camera for poor battery life. but if a battery lasts a year i would say that it's a pretty good . hope this helps you.....please rate this

That is not good, by the way is there a possibility that the battery is over charge? because overcharging it will cause some damage on the battery and it will only good for a few months...

Hope that helps........
