Most cheap rechargable batteries are only 1.2 volts instead of 1.5 volts. There are different kinds of rechargable batteries, so you must make sure you get the kind designed for digital electronic equipment such as cameras and rated for 1.5 volts and not cheap kind rated for 1.2 volts. What does the package say for how many volts it's good for?
Personally, I just buy regular batteries in bulk packs of 120 or more batteries at a time.
