are my nimh batts toast?!?!?
 
well guys and gals i got some maxamps batteries last march and they were awsome, tons of power 20 min runtimes and lots of fun. well my e-maxx broke after about 20 runs on the batts and i remember charging them up and putting em away. well i finally got my ultimate 400oz torque servo and i charged up the batts and away i went. well i got about 2 mins of all out running thenthey totally dumped. the truck wouldnt even move. so im like okay W/E i got my other set charging so i got it all hooked back up with the most recent charged set and away i went, and again about 2 mins of all out runnn then a total dump that wouldnt even let the truck move. are my batts toast?? or are they still sleeping and i need to charge em a few times to wake em back up or something? -Wes

Try cycling them several times.

how long did they sit for?

^ See above. NiMH really HATE sitting around for vey long. Once they completely self-discharge they're done.

they sat for about 2 months maybe that if not less. when i plugged them both in they were at 16V so they didnt discharge a whole lot. -Wes

Hmmm...

well i think im guuna try and charge and discharge em(its called cycle right?) and see how that works. what do you think should be the min i discharge the batts to? (both batts are hooked up at the same time) i have a triton 2 charger. -Wes

the samething happened to some NiMhs I had for a 18t and I assumed they were gone and i converted over to Lipos

okay well i charged them then discharged them and then charged them and tried them and they wrked great. still lacking a little punch buttt i can wheelie now, so im thinking a few more cycles and they should be great. -Wes
