batteries getting hot when charging?
i just recieved three 3600 NiMh and i cycled one, and tired to quick charge it with my dynamite Mega2 charger (the one with the 15min dial) and i charged it for 40 minuets, and it started to get warm so i took it off, i ran it in my pede and it seemed like a good charge, when it died i let it cool, and pluged it into my MRC 819 SuperBrain to peak charge it, and i noticed after about 45-50 minuets it was still not done, and decently warm/hot i unplugged it, and let it cool off
how hot should batteries get when charging, and how long do 3600 NiMh usually take to charge??

generaly a battery will heat up as it aproaches its peak. it should be a little warm/hot. BUT, if it is uncomfortable to touch, or too hot to touch, that IS too hot.
i would suggest charging at a lower rate if possible with the 819.
cheers!

The Superbrain should detect a peak and shut off when there done.. I do know some 3600mah batts to hold a 4200mah charge when new..
