Cordless Tool Batteries

[Magnimike1]

Is there a local place that rebuilds cordless batteries? I have 7 Dewalt batteries that are dead.

I found a rebuilder online that is about half the price of new replacements.

You should be able to shock them and bring 'em back. Dig around on youtube to search for it.

Thanks for the tip on shocking them. I've got about ten of these pos ryobi 18 volters that don't seem to last beyond five or six months...

I buy my own cells on Ebay or other online vendors and rebuild them myself. It is not hard to do.

Then do explain how to do it.

Then do explain how to do it.

The batteries are in series parallel. Google that once you understand how that works it's cake to do it yourself.
You never pay attention to this but when you put batteries in a remote your doing series parallel most of the time.

If you have three car batteries with each rated 12 volts and 500 amp

Series:

Example connect negative to positive.... on all three batteries together. Now you have 36Volts and 500 amps.

Parallel:

Connect all three positives together and all three negatives together. Now you get 12 Volts and 1500 Amps.

When you jump start a car it's hooked up parallel (your using the amps to start the car and keeping it at 12 volts). When you put the positive behind the negative on a remote your putting it in series.

I used to rebuilt NiCad cordless phone, RC car, and multi-cell packs all the time...very easy to do. LiIon laptop batteries are a tad more complicated because of how tightly they are crammed together but I've rebuilt a few of those too. Hell of a lot cheaper than paying someone else to do it or buying some no-name ebay crap that uses shit cells.

Thanks for the info.

I've used the shocker a few times with good results.

Oh, btw, you can shock those batteries too. I have done it then marked a date on it. I got another year and a half out of some and I am about to shock them again.

Buy Lipo battery operated tools...

Ryobi lipo's are no better than the nicad version . I just bought $1000 worth of millwalkie impacts and ratchets . 18v lipo with a 3 yr warranty on batteries and 5 year warranty on the tools. They are gonna hate me .
