What could be the cause and solution to battery drain on my Olympus FE-110?

Have you fully charged the battery? if it is a new camera or battery,it needs at least 12 hrs of charge,to maintain good charge, if only a short time of charge was given from new the life of the battery will be greatly re-juiced,try a new battery with a full charge, if this fails your camera is probably faulty, take it back to get a replacement.

You have a pretty heavy drain on your battery. Find the fuse box. Remove all the fuses. With volt/ohm meter, read each fuse socket to find which one is drawing the power - when you find it ... investigate the circuit to find the short.

It may be that you are not making power ... your rectifier may be shorted which not only prohibits charging ... in some circumstances, it will actually cause a short to ground.

Do you experience low battery? Have you tried using brand new and fully charged rechargeable batteries like NiMH or NiCd?

I didn't have the time to find out what was the problem cause i needed the camera immediately so i bought a new battery and a new charger.Thanks for the help!!

extra dose 12V power pinch for 3 sec

this problem seems to be caused by a faulty battery protection switch fault, which is situated in the battery compartment.

Have you tried replacing it with fully charged NiMH? Bizzarro, Cavite City.

It sounds to me like you are not waiting for the camera to charge the flash when turning the camera on or between shots. It seems you are using 1700mAh batteries and most modern digital cameras are better off using 2500mAh batteries. Your camera was released in September 2006 so it is considered "modern". With 1700mAh batteries, your flash (warm-up) recycle time time will be rather long or the amperage may not be enough to fully charge the flash unit. I highly recommend Duracell 2500mAh rechargeable batteries.

Open the battery door and check the contact between the camera and the batteries. Most often then not there is just a bad contact and it's ruinning your baterry life.
Make sure that the contact are well placed and that there is no rust or dirt build up around there.

are u using recharchable bateries??? if don´t use that ones (over 2000mAh ones) that camera just drains batteries.
