Thanks for creating this DIY! I have an 18v Coleman that came with two batteries that have since crapped out (after less than a year). Couldn't find replacement batteries. With this DIY I can now I can replace the innards of a perfectly good cordless drill.
I have one question, though. Should I get the 2900mAh or the 1600mAh sub-Cs? What's the difference?

Look for "hamfests" in your area. There is always a person(s) selling various size/charge/discharge ratesd batts. The prices are usually as good as through th email and you have them in hand. They aren't fligh by night (usually), cause hams talk to each other and a welscher will be found and ostracized.

nice instructable

Looks great, I always meant to do this to my old drill before it walked off. Its always a rip-off to buy a new battery pack from the store!

Nice.

I did this last year to an old drill I got from a 'flea' market.

The local B&Q had several battery packs for various drills on sale at £5 each (around $7-$8, I think), so I bought a couple to make up the voltage I needed, but also made sure I used 1800mAh rather than the 1400mAh originals. The slight downside is needing a couple of extra hours to recharge (with the original charger), but that is balanced by the reduced likelihood of overheating.

I ended up cutting an old household power lead for my 'tabs', as I was concerned about the potential heat generated - and I couldn't think what else to use. It was a bit of a pain to close the pack up again, but I've had no problems since.

The drill has worked fine ever since - VERY powerful and almost, perhaps, a little too fast for screwdriving.

Wasn't there an Battery pak system mod to power an Electrically assisted Bicycle using Dewalt batteries.
