Here is the next pack rebuild…An older Polarion 4S2P pack…
Will likely go with either the Moli M35A or the upcoming Moli P30A (for a potentially larger safety margin)
Yes and No.
You have to buy Ridgid from Home Depot to get the lifetime service. You also have to register the tool AND they have to approve you. Meaning, if you violate any terms to the agreement, they wont approve you. Even then, I don’t think they will be giving you free batteries indefinitely.
Bottom line, rebuilding battery packs is risky business. NiCAD for example is dated technology. Dont bother. As for lithium, buy a new pack from the manufacturer. Lets face it, if the original pack lasts 5 years, you replace it one time and you get another 5 years, by then the tool is obsolete or too worn out to use.
Now on the other hand, if you want to do it to prove it can be done, there is absolutely nothing wrong with that.
My 18 volt Dewalt hammer drill is 21 years young and still going strong. Drilled all the holes for wiring a few houses. Driven thousands of long screws. Have not used it too much for hammer drilling. Replaced the NiCADS I think twice plus the originals. I have a bunch of other tools that take the same batteries, circular saw, recip. saw, lights, a second hammer drill, impact driver. I think I will stick with it now since my building days are numbered.
Hi! I had excellent success with buying old, dirt-cheap Dewalt 12V tools on ebay and restoring those. I have made a thread here in german, maybe google translate will help, and at least it has lots of images:
