Drill battery refresh

Cordless drill batteries. Generally you can buy a new drill with 2 batteries and a charger for less than buying a new battery, and that's just wrong....

My first cordless drill: Wen, 9.6volt, not variable speed. Battery didn't last all that long, but we knew a guy that worked at Battery Plus, and he put in new cells for me. Those didn't last long, either.




2nd: Craftsman 13.2v. This was a good drill, and I used it a lot, till the batteries started failing. It was really long, from chuck to the end of the drill, so it didn't get into very small places. Plus it didn't stand up on the battery like most do now, but it was still balanced pretty well.



3rd Milwaukee 18v. Got this used, had a 1/2" chuck, which had a broken jaw, which really didn't affect it. It was also a good drill, and I'd be rebuilding the batteries for it, but it got stolen out of the garage.

4th Makita 12v. NiHd Good drill, bad batteries. I bought a set of NiCd from ebay a few years ago instead of rebuilding the battery packs. Seems like one of those batteries was not working right, but maybe giving it some love and threats has brought it back. Old and new:



5th Rockwell 12v lithium impact driver. Not a drill, exactly, but a driver. Was AWESOME but was stolen from the garage along with the Milwaukee. The lithium lasted nearly forever and would drive a lot of screws. Charged fast, too.

6th 12V Masterforce Menards brand  lithium drill/impact kit. These are awesome, too. I think I bought them when the Makita was not cooperating, and I said "I'm not buying more batteries for that POS". Got the kit on sale and a rebate, too, was quite cheap. Small, lightweight, has lights and works great.

I bought enough 2200mh batteries from ebay to rebuild the 2 Makitas, 1 Crapsman, and the Wen. My plan is to put one in the garage, and carry one in the car in case I find something in a dumpster that needs to be taken apart before I take it home.

The interesting/irritating thing about these batteries....Well, a couple things. The new batteries, the green ones have tabs already applied to them, pointing the same direction, with a piece of heat shrink tube on them. That has to be cut off. The tabs never need to go the same direction. But some patience and it comes together.

The other thing? The old batteries still hold a charge and seem to work. I don't have a real method to test them, to see how long or how much charge they hold....but they work well enough to power some LED lights for testing.

Drill needs new batteries? Bring it over, I'll help you fix it up.
