Default 9 year old battery?

i go this off road buggy monster from radio shack when i was like 9 i'm now 18 and i was going thru some old boxes in the garage and found it, i though i had thrown it out years ago but i guess not but i threw it away but i did save the battery because i thought i might be able to use it as a back up and a test battery, so its like 9 years old its from radio shack its a ni-cd 7.2v 17000mah
so i hooked it up to my superbrain at 4 amps and it was charging so i checked after 10 minutes and it was a 8.23 volts! i shut it off and here i am 8.23 volts is way over the 7.2v its says on the pack i dont want to blow anything up?

best thing to do is charge it up normally with a peak detection charger.. cycle it and then charge it again.

nicad even if theyre ancient if not abused will still charge up..

1700's were good if they were sanyos.. the panasonics were unstable.. and could explode.

if you're unsure call the bomb squad and dispose of properly

DUDE....These "7.2" volt batterys could charge up to & past 9v

I wouldn't be worried until it hit 9.7 or so

If youv'e been charging your GP 3300s up to 7.2v than I honestly feel sorry for you....LOL

Iv'e got some old 1400 nicad's that I used to use for a nitro starter box....while charging (because of the high resistance that these Junk cells have) they would go up to around 11.7 volts on my GFX and on my quasar pro......if I re-peaked them, they would go up way over 12 volts.......the minute you disconnect them there down to around 7.5 to 8 volts............it's normal

Just charge them up untill there pretty warm to the touch......this way there's little risk of having to have the bomb squad out to your house
