Energizer 2500 mah AA NiMH batteries

I was surprised to see that these are now available, even at Walmart.
Essentially the same price as the earlier 2300's and the 2100's before
that. Good price (4@ $10) for good batteries.

how much more can they increase those little batts.......has anyone actually
tested the specifications............us non tech beings must take their word
for it.............it might just be a change in case printing that's why
there is no extra charge....

what do we think

I tried the 2300mAH batteries. Used the same Maha 204F charger I've
used with various other battery brands for several years. The initial
perfromance was great but after about 10 recharge cycles they literally
died. Anyone else have similar experience?

It makes sense that a battery design that increases capacity would have
the side effect of reducing longevity (or increasing weight and/or cost).

Is measuring 100 milliamps for 23 hours ths same as measuring 1 milliamp
for 2300 hours? Anybody know? Such a test would not be hard to perform.

No.

Anybody know?

Only approximately, but for starters, the extremes will deliver less
life than rated; the low-drain case because it is competing with
self-discharge for depletion of the charge, and the high-drain case
because useful life is wasted through heat.

No free lunch. Reliability, self-discharge rate, and the number of
charge/discharge cycles will all be degraded. As to the question about
rapid discharge, none of them reach their rated capacity at high discharge
rates. In other words, less current drain generally yields better capacity
(until the self discharge factor kicks in).

Good info and down near the bottom, he discusses testing
methods and amphour ratings etc. Some good info there
(besides, you wouldn't get 1 ma for 2300 hours -- it would
"self discharge" before that !!)
