My camera uses AAA batteries, and I have a few sets of NiMH AAAs. I know that these are only good for a certain number of charge cycles, but how can I tell when it's time to replace them?
I've been charging each AAA by itself, then immediately testing it - if it doesn't show "green", then I assume it's dying. (I have Sanyo smart charger, which shows power as red/yellow/green.)
Is there a better way to test them?
