My car's battery was half used so I decided to charge it a bit. It's a nimh and I have a nicd charger. It takes 12 hours for a full charge, and I was gonna charge for 6 hours but forgot to turn it off. the charger doesn't turn off automatically, so it's been charging for 24 hours. The battery was not hot when I noticed and turned it off, it was cold. its a 1400mah 5 cell pack for my ravager. Will the battery be affected? Did I kill its life span or capacity? Or will it be fine? Thanks..

a wall charger has such a low current that it won't do any harm to your batteries!

Wall chargers are fine for receiver packs........you didnt harm anything, if anything you equalized the cells.

guys, he said he charged a NIMH battery with a NICD charger! you shouldnt do that, you should charge the type of battery with the right type of charger. imagine charging a lipo using a nimh charger [&:][&:][&:][&:][&:]

Yes, a lipo would be plain stupid. This is a wall charger though, it puts out like 120 ma, not enough to harm it, and if he did it would be burning hot.

there was no nimh charger, the hobby shop said i can use a nicd one if i turn it off on time.

It would be the last time I bought a thing from that hobby shop as with nicd batteries have a memory so in order to charge them they have to be total discharged before charge. With NiMH you do not ever want to total discharge them. Most chargers for nicd batteries total discharge before recharging. Boy did that hobby shop ever blow smoke up your backside just to make a sale.

its a cheap wall charger for $5, i doubt it discharges. And yea, the shop always gives me these homemade ideas for fixing stuff.

I guess the smoke worked do not take my work for it email a battery manufactory and see what they say. If it worked for both type batteries why would they mark it one or the other but its your money not mine. All so two different type batteries charge at different rates.
Good Luck

Charging 2/3 A nimh receiver pack with any slow charger, such as the 120mA will not harm the battery pack.

As for the statement that most nicad chargers automatically discharge the pack prior to charging, that's a load of smoke up one's backside. NO CHARGER AUTOMATICALLY DISCHARGES A PACK PRIOR TO CHARGING NICADS!!!!!! It's true that nicads should be discharged prior to charging. HOWEVER, the battery should be allowed to "rest" and cool to room temperature prior to charging. There are no Tekin, Novak, Integy, or Competition Electronics chargers that discharge a pack as the beginning of a charge cycle. My chargers will do that for conitioning batteries, but never for charging.

Keep us posted on how long your battery pack last and good luck.

my car is waiting for a head button, so it might take a while. Even when I get it, my battery usually lasts 2-3 weeks.
