my wife needs batteries for a new york trip she's leaving for in the morning, and asked me to set her up with some batteries.
i'm sure she knew i would over do it and of course i did.
i used my la crosse bc900 to digitally check the voltage level of all 30 of my aa batteries.
the ones that were hot at 1.40 volts i put in her camera bag.
the ones 1.3-1.39 i put in a slow charger for her till 3am when she leaves.
the rest stay home with me.
well anyways, i realized i can set that charger to discharge up to .5 amp and THEN read the voltage.
this will really tell you what a battery is made of.
the duracell 2650 (which by the way, really are 2650mah) performed very well under that load. so did the eneloops and the rayovak hybrids.
what didn't was some older ones of mine, the no-names like "digital" or walmart batteries.
right now i have in duracells that were 1.27, they sagged to 1.14
the digitals were 1.30, they sagged to 1.03 and .98
.5amp is not even much of a load if i'm not mistaken.
put that in a single aa that requires .5amp at 3.6volts and we're pulling 1.5 amp from that battery. i wonder how the difference would be then.
anyways, i thought i would share what i found.
nice feature of the digital battery testers.
