I had taken on the task of going through my dozens of AAs and weeding out the duds (some are over seven years old).

Well.........turns out over 80% seemed useless.....won't charge or would only take a half-assed charge.

Instead of tossing them I studied a while on how to possibly rejuvenate them through a series of controlled charge/discharge cycles.

This was too hard to do with my inexpensive charger, so I bought a MAHA MH-C9000 charger ($50), which has a couple features that will fix old batteries.

After about thirty hours, my first set of "duds" seems to be satisfactorily refurbished.

Just thought I'd let y'all know.....this is a really cool charger, complete with a readout that allows you to monitor and evaluate batteries individually.

I think I saw the "Secret of Nihm" once...

hey Andy.. can I just send you my dead batteries to be fixed..?? $50 for a charger is a little steep for me...

$50 for a charger?

That's like paying $90 to repair a $70 DVD player...

only if you have 20 dvd players to fix

I see dead batteries.

Check the humidity.

48 AA NiMH batteries...........approx $4 ea.

$50 is well worth it.

you pay $4 for a single AA battery?

I have a few brand new ones I will sell you for $2 each. An unlimited supply.

^also note.....a lot of the inexpensive chargers (like the ones that come with batteries) will junk your batteries pretty quickly.

So........you spend $25 on an Energizer charger and four batteries......put the batteries in your camera, find that rare opportunity for a perfect picture, try to snap it, find out you have no juice, reach for your spares, get them into the camera just in time to realize that they have discharged because the initial charge was ****, then go home and throw all the **** away and look to buy a good charger.

TW.......s'been a while since I bought any, but I recall paying that for good high cap NiMH batteries.

I've bought off brands cheaper than that too, but they sucked ass.

I've got 6 sets of 4 that I rotate out every year . . . It can get expensive . . .
