DeWalt 18V Power Tool Batteries

Pop on the reading glasses as there should be some mention of the battery chemistry on the unit.
That, or tear into the batt pack itself. Never had any real success repairing them, as a new complete unit would cost close to the same price as a rebuild.
Love my Milwaukee M12 so far.

Thanks. No mention of chemistry on the pack. A new DeWalt is about $90, a new clone about $18. Maybe the clone is the way to go?
I am only interested because I have some sophisticated charging and cycling equipment for various battery chemistries, and I know NiCds can get "stuck," and be rejuvenated.

I don't think they are NiCds. The 14 volt ones, as I recall, were (for a while).
The challenge is that the replacement battery packs are almost as much as new "package" with the drill and everything (if you can still get the same battery packs).
If you've burned through both battery packs, you probably need brushes replaced, etc. anyway? They'll have "Christmas" deals shortly...Merry, merry.

If the tool is older than 4-5 years, I think it would be NiCd.. I had 18V Ryobi batteries from before that which were all NiCd.. They made the 18V Li batts backwards compatible and had a sale of two batts and a Li charger for $100. The cool thing is that they work on all my Ryobi stuff.. and immensely improve performance. I did look at opening the NiCd packs and found that they had used "C" sized batteries. I was going to rebuild using NiMH then I saw that the new Li-ion batts were just a tad more than the cost of all the "C" Li batts.
Batteries + will replace the worn cells in the battery packs. I am on my fourth cell replacement set in my Snap-On 12V battery pack set. 20 years of good service from that drill. Batteries + puts the date on their label so I can remember how long that set of cells lasted. About 1/3rd the cost of a replacement battery pack. If it is a cheap drill just buy a new one. My newest drill is a 20V DeWalt, I like the light weight and quick recharging of the battery packs.
Soon they will make drills that are 120V. We can then plug those drills into a standard wall socket and never have to fret over battery life or state of charge!

Thanks. The dead ones I have on hand are DC9099. I will try to determine if they are essentially the same.
What I am hoping to accomplish first, is to "jolt" these into accepting a charge. There is a NiCd phenomenon where they won't accept a charge if they've been discharged to far, and can be brought back to life, Frankenstein-style, by briefly applying the full charge voltage.

Based on the info in the link, they are NiCAD. https://www.amazon.ca/DeWALT-DC9099-Profile-Battery-Brand/dp/B0017654SY
Of course, this info is wqorth exactly what I paid for it. ;-)

DeWalt makes an adapter to use the new 20 volt Lithium Ion batteries on the old 18 volt stuff.
That is the way to go. I hated to do it but I gave up on my 14.4 De Walt stuff and went with the new 20 volt and was thrilled afterwards they go and go and go. They are also MUCH lighter.
