Yellow:

It sounds like you were using a regular cheap NiCd charger... and you should always check the temp on 'em before attempting to crank the dial a second time. Better yet, rig a multi-meter to see where your voltage is at... its the way we 'old-timers' used to 'peak' out packs before peak-detection digital ones came about.

Was it a NiMH pack you were charging? Thya could explain things... using the crank-dialers to trickle charge, aka slow charge, which they do when plugged in and NOT cranked, on niMH is fine... but using it on a NiMH is not recommended as the unit isn't designed for that kind of battery. You CAN use it, but you have to monitor the pack carefully...

And yes, as the guys said, you probably blew at ~least~ one cell. Unless you know someone that rebuilds packs, you're going to need a new pack, as this one's going to be short at least 1.2-1.5v (depending on where it would peak before)

If you want a good digital charger thats not too expensive, and can be used at home, and off a car battery at the track, I'd recommend the duraTrax DTXP4005 DuraTrax "Piranha AC/DC Digital Peak Charger", list at Tower of $49.99: http://www3.towerhobbies.com/cgi-bin...?&I=LXCLD5&P=7

Hope that helps ya out.
