cordless drill battery wont charge?

Hi,

Sounds like the charger, you could use a volt meter to test it. Some batteries fail sooner than others, i have a 12v De Walt drill/driver with same batteries from 1994 but the 18v circular saw battery lasted only 3 years, go figure.

You can try zapping the battery packs with a welder per the referenced URL. I've never done that personally but I've had quite good success zapping individual Ni-Cd batteries with an auto battery charger and it's worth a try. You definitely need a higher current and/or voltage source to successfully zap a battery pack with its array of series and parallel connected cells. If that doesn't work, if you're handy you can try rebuilding the battery pack by disassembling it and testing/replacing the bad individual Ni-Cd sub-C cells. There are several good sources online for detailed info on how to do that. I also happen to own a DeWalt cordless drill with 2 battery packs that are slowly going bad and that's what I plan to do when they finally fail. Replacement battery packs are ridiculously overpriced and are only a last resort. Good luck!

It seems that if you put your battery in the charger and no lights come on ,the charger is the problem..........Im not familiar with that brand ,but when I plug in a battery in my dewalt or hilti charger I have a lit light even if the battery is shot.......

replace the battery.. if its still under warranty use the warranty. most tools have a 1 yr warranty.

it happens every single person who use like yours drill.

in first time to use that it might not work.

but if give all effort on try to keep up with that drill

it will work,

i mean that drill is same battery with others.

so keep try to on it.

Something is wrong with the charger

problematic point. do a search with google or bing. that will could help!
