Question About Overcharged Batteries

So like an idiot I set up my battery to my charger and left it on for the night after I fell asleep. It's a 1500 NiCD battery and I'm only supposed to charge it for a total of 4 hours (so says the manual). So is this battery dead basically? Or can I hook it up to my gun and test it without hurting my weapon? Or should I just buy a whole new battery altogether and forget about this one?

Any help would be greatly appreciated, thanks guys.

the bad news is that you rewand the battery but the good news is that it shouldnt hurt the gun.... when you charge the battery to long it hurts the battery run time ( there for the battery dies very fast) and you should get a new battery and not over charge the new one.

kkoerber pretty much nailed it,

By overcharging your battery you are attempting to push more of a charge into it than it is capable of handling, you may be able to use it as an emergency back up, but sooner or later it will no longer hold a charge.

your best bet is to invest in a Battery charger that will stop automatically after the proper charge is achieved.

Both Slob and Kkoerber are correct, however I've over-charged my battery several times and some of the still work. Yes, the battery will eventually die and no longer hold a charge, but that could be a week, it could be two years. Ive gone through SO many batteries, for me its always different. One small tyoe 8.4v battery I left in for over four hours PAST trhe charge limit MULTIPULE times, and it still works. HOWEVER, it makes any gun I put into it nutty and makes semi-auto full auto, dies then suddenly works, and so-forth. Another Large-type 8. battery, I accidently left charging for four days, and anpther time, not even a week later, three days. And It doesnt hold charge quite as long, but still maintains a great RPM and works just fine. So it really depends IMO. Oh and BTW: To my knowledge; no, the over-charged battery can't hurt the gun.

What would be your guys' suggestions for the longest lasting battery that would fit into a somewhat limited budget. The gun I own is a Full-metal JG MP5

Oh and thanks a lot for the help. I went and shot my gun earlier today and it seemed to work fine.

get a small to large type converter, and a external battery bag and find a 9.6 3600 to 4000 mah battery. If you get an 8.4v the battery will last even longer.

or, u culd buy a smart charger for 30 bucks and not have a care in the world. lol
