Just a heads up for those who might need new batteries.
My DeWalt 7.2 volt driver is my go-to driver for light duty work. Had it for about 8 years. Well, the batt finally died, and I was searching for a replacement. Found one on Amazon for $16.99. HUH! That sure sounds like my price range, but is it worth a crap?
Got it, charged it, and it sure seems to be a winner. 1 year warranty from supplier. We’ll see.
In case ya want to know, it’s from Powerextra.
No connection. Just a customer.

That’s great! In many cases the replacement batteries are as costly as the original tool.

If you have a powerful soldering iron, you can solder in new battery cells. They are standard A123 batteries that you can buy on ebay for a few bucks each. There’s a few how-to’s on the web.

NiCd batteries are great, aren’t they ?!? :)

They last longer and are significantly cheaper than NiMH and Lithium… Replacement batteries for my Makitas are about $14 a piece, and they are higher capacity than the originals. As Jerry points out, the newer batteries can be really stupid expensive.

Please remember that this is a new battery. I have NO idea how well it will function. I will be SURE to post a follow up.

To prolong battery life limit the charge time. They have a certain amount of charges expected for what the manufacture has determined is a “lifetime” Letting them sit on the charger to “trickle charge, or maint charge” is still a “charge” against the overall battery life. Most of the new stuff is 1 hour charge. A little time to build a charging station that has a timer you can set to turn off the power to the unit charger prolongs the battery life.
