Energizer 2500 mah AA NiMH batteries

Archived from groups: rec.photo.digital (More info?)

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.

I start holding my tongue in my cheek when I read some battery specifications.

Stereo makers have been inflating amplifier's wattage for years. Just recently
there was a class action law suit in the US forcing air compressor manufacturers
to state the true horsepower of their electric motors. Many '5 Hp' compressors
being sold by large respected firms weren't much over 1 real Hp.

I'm not saying Energizer's claims are false, but I do *really* wonder about the
ratings of some of the Taiwanese and Korean knock off batteries you see on eBay.

LOL!
A Panasonic kit I bought at Costco contains AA NiMH's that state:
"Up to 2100 mAH". That means even when they go totally _dead_ ,
they'll still meet manufacturer's spec's. sigh...

However, they do seem to perform "ok". But, I really like the Panasonic
charger: It's a plug-into-the-wall module with a fold away mains
plug, and it runs on 100-240 VAC, 50/60 cycles. Great for traveling.

No.

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.

Check out the "great battery shootout" at
http://www.imaging-resource.com/ACCS/BATTS/BATTS.HTM
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 !!)
