I charged Energizer batteries on the Energizer Battery charger I bought. When I put them in my camera and turned it on, it read, " Warning!! Battery Exhausted." How can increase my battery life?

I have this issue with one of the batteries in my set. (Purchased last summer). It is a PL-7522

It seams to be the battery, as I have tried combination of charging ports and controllers. The other battery seams fine.

Plug it into mains without battery.
Put the battery(s) into place. If batteries OK (but need charging) it will begin charging. If batteries very low it will cut off. If batteries charged it will charge only 1 - 10s.

wHEN THE GREEN LIGHTS COME ON IT TAKES ABOUT 12 HOURS TO FULLY CHARGE THE BATTERIES. WWHEN CHARGED THE LIGHTS GO OUT. Ken13

I have the exact same camera almost a year too. It is a total "swinka" on batteries. About 10-15 shots on super ni-cads, and quits without warning.

A pair of Energizer 7X gave me near 500 shots. Much cheaper but still ...

So 4 months ago I bought a charger and 2 rechargeables. Charge one while using the other one.
I may get 70-90 shots per charge on these lithium-ion rechargeable batteries, without flash.

Testing the batteries without a load doesn't really tell you anything.
What's the reading? Should be well over 4 volts when fully charged. Mine show 4.2V

It sounds like the PC Board which provides the circuitry for the Charger's indicating light is malfuntioning. If you have a DC volt-meter, you can check the Charger's output voltage, and then the Battery voltage to determine if your charger is functioning.

Hint: If the Charger has an output voltage, but the Battery's voltage is less than its rated voltage... it's time for a new battery.

The NI-MH batteries are the Best for use with Digital cameras....U need to Charge the New Battery for 12 Hours The First time and then 2-3 hours for every other time you charge ... try and check please

sounds like your battery or charger might be defective. I have this camera an when the battery is to low it flashes the screen.
I still use the original charger that came with it to charge the batteries,been thru 4 of those. It seems if they set a while without being charged the go bad.

Try Eneloop batteries from Sanyo. They have the higher voltage needed. AND that voltage doesn't sag under the initial startup load.

did you use comapny authorised battery if not go for it
