WHOA! battery did something REAL strange!

[A RC Dude]

ok, i was digging out some old stuff and i found my old 6 cell gp pack i used to run b4 i got 3800mah packs whitch was b4 my LiPo. so i decided to sell it but b4 i did i needed to be sure that it worked right first. so i go hook it into a 23T titan motor and it didn't even make a noise. then i hook it up to the super brain and it said that the pack had .50 volts in it! so i set it to charge and then 2 or 3 seconds later i looked at it and it was reading 8.95 volts!!!!! so then i think that couldn't be right!! so to be sure, i take it off the charger and hooked it into the motor agian. this time b4 the wire tuched to motor thare was a HUGE spark and the motor spead up like it was running off 14 volts like when in the e-maxx!!!!!

it was charging at 6.00 amps and for only about 2 seconds! thare's no way it could have gained 8.45 volts in 2 seconds at that setting!!!!!!! but somehow, it apeared that it did.

anyone have a clue how that could have happened???
