    Your going to have to be more specific, was the battery a little warm when you pulled it off the charger?

    What is a smart/quick charger? How long is it charging before it says it's through? If your using NiCD batts, they should be a little warm after charging or they're not done charging.

    If its a timer charger, check the fuse, it may be blown.

    i checked the fuze and it was fine. i charged it over night and it worked great. i noticed that after i pulled it out of my car it was really hot. i could barely hold it. it's the first time i've drove it in warm wheather. is this normal?

    i always peak my cells.i monitor the voltage with a digital volt meter.when the battery starts to get warm i look at the voltage.when it stops going up and drops .1 or .2 volts the battery is peaked.while still warm i run it in my car.this is the way to get the most out of a pack.
