Battery exausted problem

Always be sure the battery is charged and suited for your camera.
Check contacts of the battery and in the battery compartment of your camera. Dirty or oxidised contacts can be cleaned with a dry cloth. Never use sharp tools to clean contacts or anything in or on your camera.
Always charge the battery before using it for the first time, or if you have not used it for a long period. 3 months is a very long period.
Also check if the battery door is closed correct. Most cameras do have a switch connected to the battery door. If the switch does not work correct, it could be you can't switch on your camera.
If you have a multi meter, you can check your battery. After charging the voltage should be higher (few tenths of a volt) than the voltage printed on the battery.
If the voltage is slightly lower, you know thee will be not enough left when the battery needs to deliver some power.
Do not use alkaline batteries unless it is absolutely necessary. In some cases, alkaline batteries may have a shorter service life than NiMH. Alkaline battery performance is limited, especially at low temperatures. The use of NiMH batteries is recommended.
Never use manganese (Zinc-Carbon) batteries in your camera.

Hi, possible causes:
Completely exausted battery.
Charger or Usb cable bad.
Fuse open in charge circuit or several damage.

Greethings.

Make sure with a good test if the battery on the camera has the VOLTAGE AND CURRENT that is required for the camera to switch on, Sometimes only the voltage is present on some battery which will not allow the camera to switch on.
if this is confirmed then there is fault in the terminals of the camera battery holder, fault in the main controller electronic unit.
If technically able to open you can remove to check within for any switch contact failure, barring which it can be failure of the controller unit.

There are tiny Li batteries to maintain the short term memory for interim period. Normally they last very long but unexpected can be expected. You may not have enough tools to open it & reach there. Either go to camera repair or just entering it everytime or give it to the kids & buy new one instead of repair.. [email protected]

The problem may be due to corrosion on the battery contacts inside the camera. Remove the batteries and wipe the inside contacts firmly with a dry cloth (heavy corrosion may require cleaning with a wire brush, steel wool, or sand paper). Remove any residue that may have fallen into the battery compartment during cleaning, wipe the ends of the batteries, and replace them in the camera. This cleaning process works about 90% of the time, and I hope that it cures your problem.

You will need to get replacement Photo Conductor units.

I beleive your batteries are of incorrect type or you need to set the type of the battery through menu. My favorite batteries are from Wal-mart: Energizer rechargeable Ni-Mh 2450mAh, (15 min recharging time) they fit any type of camera without setting the battery type through menu. Some incorrect type of batteries often damage the CCD. Ni-Mh Energizer never damages the CCD (black screen), while regular (non-rechargeable) Energizers may damage CCD in Sony S700 or similar cameras.

are you using regular batteries? if so you need to you camera batteries. they last a long time

I don't know if I have the very same problem with my old nikon Coolpix E44600. I may go through the pictures I have already taken but when I try to take a new one, just as I shoot I get the message the "battery exausted" message and the camera shut down.

Wet ingression - turning on killed it. This is not going to get repaired. Put in a warm dry place for a couple of days with the batteries and card out. But don't put your hopes too high.
