Yeah, I've wondered about this too. I've read that certain
manufacturers warn about the use of high capacity batteries.
Add to this that 'AA' NiMH cells are now available in 2700mAh (Sanyo
commercial grade) and that the market is very competitive and
capacities are likely to increase.
I've found that getting a good charger isn't easy. I bought a very
sophisticated model from Radio Shack a number of years ago -- voltage
readout, auto-discharge, pulse and fast charging. Woo-hoo! All the
batteries I used and subsequently bought proved to be relatively short
lived. Or so I thought. It finally occurred to me that the damn
super charger might be 'off'. So I bought an EverReady charger.
Better but still not quite right. Then a simple "overnight" RS
charger and wham! All of a sudden my "bad batteries" were quite
strong.
What I'd like to know is how does one *test* a charger?
