Re: A cheap way to rebuild cordless tool battery packs.

Hi, Anyone ever try this? www.cordlesstoolbatteryrepair.com
Seems cheap enough to give it a try for only $3.99, says 98% success rate with over 1000 sold. I really don't want to spend $90 for a couple new dewalt batteries. I think I might try it.

Re: A cheap way to rebuild cordless tool battery packs.

Hey, just wanted to follow up on this repair eBook. I bought it the other day for $5.99, and it seems to have brought some new life to my 18 volt Dewalts. Theres 3 or 4 steps and it takes about 5 minutes to complete {very easy!} It can be found here ----> Cordless tool battery repair Its worth a try for the price :cool:

Have you tried Ebay? Try this link http://stores.ebay.com/RUBYGIRLS-TOOLS_W0QQssPageNameZSTRKQ3aMEFSXQ3aSSTQQtZkm

Good luck,

Re: A cheap way to rebuild cordless tool battery packs.

Hi folks and thanks for all the great input. As a relentless tinkerer and insatiable glutten for punishment I've been zapping (nicd)cells and patching replacements into packs for over 20 years. I also build and sell custom packs for everthing from cordless phones to 90 volt B + C batts for old radios. The net of my experience is: A shorted (dendrited) cell can be opened up by a good 12v zap but will soon short again, often the next cycle and nothing will stop it. If one cell in a pack has decided to retire it's neighbors will soon get the urge and also go south until you've replaced all one at a time. Cheap cells used to replace premium ones will soon be destroyed by the 1 hr charger regardless of their rating. All nicd packs get memory so periodically discharge to 0 volts :eek: (yes dead-flat-nadda) to get rid of that. The tool won't do it but tail light bulbs with jumper leads will (in series ofcourse for 13.2 vols and up). If you have the time and inclination try the fixes. But if you make your living with your tools or have a serious project planned your best bet is to find the best price on a genuine name brand replacement batt. Outfits that claim to repack with quality cells charge almost as much as good price on new and have little if any accountablity. So there's my 2 cents (and then some)and thanks again.

Re: A cheap way to rebuild cordless tool battery packs.

Here is a really basic article outlining what is inside a power tool battery. http://toolbatt.com/anatomy.html if your thinking of rebuilding one. I have rebuilt quite a few myself with a soldering iron. You need to be really careful not to heat up the cells to long as this can damage them. I like to hot glue all the cells together first also, this makes it much easier to work on.

Re: A cheap way to rebuild cordless tool battery packs.

I tried that years ago to no avail, these cells were dried out, even if you change the 1 or 2 that are bad, if you take the pack apart, most of the time you are gonna find out that they have leaked all over the paper wraps.
You might get another month or 2 out of them.

Have been in electronics for 20 years, I got my motto from Norm Abrams, do it the right way. I had a bunch of battery packs that were dead & did not want to spend so much money on 5 new battery packs for my drill, or even try to replace it.

So we decided to spend the big bucks & setup this family owned battery rebuild business. Being in electronics for 20 years helps a great deal.

Not only do we rebuild battery packs, we repair drills & chargers, say for example if we rebuild your battery pack & your charger quits, we will repair your charger, for only parts & shipping costs, no labor.

Can you find that anywhere else.
