I use AA batteries in my camera. I have about two dozen of them, as I use

my camera professionally.



Lately, in my good charger, when I put some in, the red light flashes,

indicating some problem. Checking them with a volt meter shows from .4 to

1.27 volts. When I put them in, and hit the "REFRESH" button quickly, it

does not engage, but the light goes to flashing. I have rotated about eight

questionable batteries in the charger in all combination of slots, and I

still get a flashing light.



Is there a way to test these batteries to tell if they are toast? I'm sure

that they are probably gone, and I need some more to replenish the quantity

I like to keep on hand. But before I do toss them, I'd like to be sure.

If you have NiMH cells reading .4V, they're not likely to ever come back to anything useful. I bought the LaCrosse charger, and I'm not sorry. Crappy chargers will kill NiMH cells.

The cells are getting cheap enough that I simply don't bother with troublesome ones. Coscto has good deals on Eneloop, but this week my local store had about a millio AAAs and no AAs. I'm going to give Gunner's source a try. I hope it's not a trap :-)
