My 2400Mah NiMh receiver pack reads over 12V when charging. I tried 3 different chargers and they all read the same. My other packs read in the 7's when charging. It peaks after a few seconds or minutes and reads 7.3V when not on the charger, but it hardly has any charge on it. Is this pack toasted, orwhat could be causing this? Thanks

Yep,to me it sounds as though your pack is toast!
If it's reading a false peak on charge and then when not on charge it's low would seem to point to a tired cell/s!

Yeah, but why would it read over 12V when charging at only .5 amps? I've never had one do that before?

OK, I ran the battery conditioner and memory eraser a couple of times and it is going down. Now it reads 9.4V, I guess I will cycle it a couple of more times and see if this brings it back. Am I doing this right? I have never had a receiver pack go bad before, but it has not been used in a while.

As i said before...invariably if your reading a false peak on charge that would seem to point to a faulty cell/cells....the cell (or cells) that are faulty are no longer giving any resistance to your readings....yes you could break the pack down and find the faulty cell but to be honest you'd be better off just buying a new pack!How old is the pack...how many cycles has it had is your main concern.

how can it be 2400?? the higest 2/3a cells iv seen are 1600

AA are up to 2700 now, though I doubt their reliability. probably a AA pack.

well thats his problem then. hes probly charging a AA pack at almost 3 amps

Hmm, i think that's what you call "presumption"!
How do you know what rate he's charging at?
Maybe try re-reading his first post....where he talks about different chargers...and his other packs....oh and in his second post he says he's charging at 0.5 amps!

It's got a cell that is shorting, this increase the surrent flow, as the charger diplays the charge voltage, it's converted it through the triangle of W/A = V and given you the answer. this wwill be higher than the packs rated volage and I bet the darn things hotter than you expected too.

That pack is toast. Get a new one.
