I always wondered why some people dislike AAs

"Regular NiMH AA rechargeable batteries were only giving me 10 shots in my new digital camera. A lot of testing and research led me to Sanyo eneloops. Now I get over 400 shots on a charge!"
10 shots to 400? Seems a little extreme to me. It simply makes me wonder the brand of the so-called "Regular NiMH AA rechargeable batteries", the age of those batteries referred to therein, the condition of the batteries, the mAH rating, if they were ever cycled or not, and the brand of charger being used as well as how they were being charged.

I know a friend put NiCads in her Nikon 2100 and had 10 shots per charge then changed to NiMh. I get about 190 photos per charge on my Nikon 3100 using 2 batteries. I've never bothered to work it out for my S1 IS. Mind, these days I use the S1 so rarely that I tend to run it on alkalines - the same as my 3100. My XT gets more use.

NiCDs can develop a "memory" unlike most NiMHs. Consequently, NiCDs need to be cycled and/or more fully discharged prior to charging unlike NiMHs. Of course, most NiMHs also need to be cycled a few times prior to holding a full charge.

I found the article interesting. I also found in a copy of Pop Photo that my wife had been reading in the loo, an advert for a Sony AA battery that kept its charge to 85% for upto a year at 68f!

I can believe it, easily... quality can vary wildly with these Ni-Mh.

I recently bought this:

2700 mAh, 1.25 volts

One batt was stone dead, wouldn't even take a charge, tested combinations of the other 3 and they wouldn't exceed a 10 minute video... I though it was my camera (canon A710). Test alkalines which easily pulled a 30 min video so I returned the batt/charger for new one + 8 extra batts.

Of the next batch (12 batts) 3 where stone dead, another pair seemed to charge fine, but the first time I turned the camera on (next day), it immediately shut off, not one picture. Another pair did make it for a 20 min video, but that's the best I got... returned them all for full refund.

Then I bought charger and batts from here, recommended from a few camera forums (worth reading this guys forums too, I learned a ton):

Holy cow.... 3.5 hours of video or 15 gigs of recording from two 2700 sanyo AAs. I've found my battery source.

Now getting the Sanyo Eneloops for the light days/weeks.

Here's some guy that tested the Eneloops on an extensive basis...last post:
