2000 nimh charging HELP!!

[wannarunem]

A friend gave me 20 AA NIMH batteries with a cheap over night charger. The light on the charger evidently doesn't work. It stys red and never turns to green..like it should...when the batts are fully charged. I really dont want to buy a charger for used batteries.
Since i can't rely on the green light to indicate a full charge i must go by the temp of the batts.

How hot should i let them get to know when a full charge is possible? Just let them warm up a little?...Or maybe slightly hotter???...any ideas???
Thanks

Not for an existing problem, but because I want compatible components the first time.

You're talking about batteries rated 2000mah, right?

Right wdavid.....just dont wanna damage the batts. So far i stop charging them when they get med warm..just before they get hot.

You need to be real careful,
One of the mods here, I wont mention names, (Christian) melted a set and burned a hole in his workbench by forgetting to unplug them.

Pay the few extra dollars and get a peak charger with an automatic shut off.

Don't just be careful with your charger , Don't even use it. Its not worth the risk.

LOL I'm glad to know I'm not the only one who used the wrong stuff to charge a battery. I used a Hobbico 905 ni cad charger to try to charge a NIMH pack and burned a hole in my workbench and also in the pack. Good news is I got a great charger out of the deal and the pack wasn't so fried that it stopped working. That was three months ago. Newayz here is the charger I am using and can't enough good about it. Although I think that ED mentioned the reverse polarity thing in the other thread and his charger might be better for wdavid hicks. Newayz her it is.

I'm not surprised folks are burning holes in benches. I hit a rub with my sons buggy and the 6 cell NiMH pack shifted forward enough to short the leads together. In the short time it took me to get to it, the amount of heat was so high that I couldn't get it out to save the buggy. The amount of energy generated when you short these things out was incredible.
