Brand new battery won't charge

[alien13]

Vision Peak 2 charger, Losi 3300 mAh NiMH, starts charging, then all the lights start flashing. Can't really return it, because the guy gave it to me for free, not knowing if it was a kit battery or what. It does come with a wall wort charger, 3 amp, should I try that?

I got two of these batteries, and the second one works fine.

Absolutely use the wall wart. That should bring it to life if there's any left.

Thanks, I'm trying that now.

Give it a minimum 3 hour charge, then try it. If it's working, run it down and run the regular charger on it.

About a week ago I had to "bring back" a couple of my good Nimh packs as well. I cycled them at low amperage like three times.The best you can do is cycle them a couple/few times at like 1A. Try discharging at a fair amperage like 10A so the packs gets some good heat in it. Maybe that'll help livin it up. It seemed to help my good packs take a stronger charge.

That was required for the niCads, but lately I have done the same for some NiMhs that have laid around too long without being freshened up.
When 2 good chargers won't keep running, only a wall wart will bring the voltage up far enough to wake them.

I've had it on the wall wart for an hour now, doubt I'll get a change to use it tonight. I'll run it tomorrow in practice and see what it does.
