Canon Powershot A540 - Change Batteries when Batteries Fully Charged

This camera takes AA batteries. You must use good alkaline batteries or better, a set of high capacity NiMH recharegables. Zinc batteries just aren't up to the task.

New rechargeable batteries are supplied only partially charged. You need to charge them fully before use.

Some of The Canon Powershot A530 and A540 cameras are subject to an advisory recall. Seems that a small spring on the battery compartment door can short out the batteries. Suspect this of yours, in that you mention that your batteries aren't lasting long. If your camera is on the list, Canon should fix this for you for free, including free shipping both ways. This is regardless of your camera's warranty status. Please check this link for more info:

Your problem may be due to corrosion on the battery contacts inside the camera which can prevent the full power of the batteries from flowing into the camera. Try this free fix before you do anything else: remove the batteries and wipe the camera contacts firmly with a dry cloth (heavy corrosion may require cleaning with a wire brush, steel wool, or sandpaper). Remove any residue that may have fallen into the battery compartment during cleaning, then wipe both ends of the batteries and place them back in the camera. This cleaning clears the problem about 90% of the time. If it doesn't work for you, the camera may have a problem that requires professional repair.

You're using the wrong batteries. You need to purchase lithium batteries. They are quality batteries for high powered, battery operated electronics. Personally, I have a battery charger and use rechargable duracell batteries. (HR6/ DC1500/ NiMH/ 1,2V) Gives you approximately 16 hrs before having to recharge.

i suggest replacing a fresh battery will most likely solve your prob, overtime rechargeable battery can drain easily, try changing with a new battery and see if it does work well, there might be insufficient current, thats why it tends to drop of voltage easily upon using, 
there is a specified lifetime for rechargeable battery, depends on your usage and charging method, theymaybe fully charged but sometimes wont give you enough power to drive 
cheers

Check your batteries. Your batteries may not be fully charged. One reason may be that you are charging batteries on a different AC Voltage supply, than what the charger is meant for; eg, charger expects 240 volts and you are charging with 110 volts.
