The Everready 2350 mAH cells I've been using for my bicycle LED headlight(2 watts draw,homemade) have been very good in regards to low self- discharge,much better than I was led to expect. I also have some "pre-charged" Ray-O-Vac NiMH marked at 2100 mAH that are advertised as holding their charge much longer.

Yeah, I know I'm weird. I use a random assortment of whatever I blunder across. Costco has Sanyo Eneloop, so I have a pile of those. I just found several 4 packs of Energizer 2300ma-hr NiMH cells, so I guess I'll use those. I have no idea what's in the camera or in the bottom of the bag, but I'll guess is some no-name brand I picked up at a ham radio flea market. I just found some Duracel 2050ma-hr cells. Oh swell, a pair of Lenmar NoMem Pro 1500 ma-hr cells in my emergency bag. Nice mess (and proud of it).

I've been running some battery tests on the new batteries for the last

4 hrs to see if I can find any "conditioning" effects. Stay tunes.

I see stuff like that as well. Though i am starting to wonder if it is just printing higher and higher numbers for the capacity without any difference in the cells themselves.

All I can say is that I have several AA battery cases for ham radios. The ICOM ones take all AA batteries that I have every put in them, the one off brand one I have that was made in the 1980's won't. It will take AA alkeline batteries and up to 1600mah Nimh batteries, but not the 2500 ones. They really are wider. :-(

I have a Ray-O-Vac 1W LED flashlight,and alkalines fit loosely,while both Everready and Ray-O-Vac NiMH are snug fits. almost worrisome snug.

they seem to be a tad longer,too.I had some NiMH cells in a plastic two cell battery holder,and they had to be forced in,despite the long spring travel of the holders,and caused the plastic to split over time. Also,the NiMH were "fat" and the holders would not keep the cells in place,they'd slowly creep out.
