The Best Batteries to Stock Up On.

The Tenergy Centura white D cells do seem good, I have 4 of ’em; but their AA cells are worthless IMO. I bought a couple dozen and within 2 years I’ve thrown at least a third of them away because they didn’t terminate properly (on various good quality chargers!). I’m not keeping AAs that accept 3200 to 4000 mAh of charge and then only show 1250-1400 on discharge.

Sure it ain’t the charger? If the charger overcooks the AAs, maybe it isn’t terminating the charge correctly.

Like trying to charge a teeny little 10440 in a regular charger, and hitting it with 1A or so. Ouch.

I once had a bad charger overcook AA NiCds because it didn’t know when to stop. The cells would start fizzing and would stink like vinegar(ish).

Nope, same bad result whether I used the Powerex MH-C9000 or the Gyrfalcon All-44. And no such problems charging my loops. Gotta be the cells.

There’s no such thing as an AA of that capacity. …

Yes, exactly my point! Any AA rated for 2k that takes 3500-4000 before it terminates is a junk cell!

What current do you charge at? If it’s too low the delta V might not be enough to trigger termination, though i’d expect them to be fully charged if that’s the case rather than terminating too early.

Charging at 1A.

[Charging at 1A.

Not too low then
