I have an 18v Milwaukee cordless drill that is about 13 years old and while the drill works fine the batteries are in dire need of new cells. The problem is that I have been unable to find a place to re-cell them and 2 new batteries cost more than a brand new drill with 2 new batteries.

Why or better yet how is it that I can buy a new drill with 2 brand new batteries for less than the cost of repairing the 2 batteries that I have now or that 2 new batteries by themselves cost more than a new drill.

I cannot seem to grasp how it is that we as a society have become accustomed to just throwing away stuff instead of repairing it. I have never done this myself but I guess I am gonna learn.

Wasn't toilet paper the first disposable item?

It might be hard to re-cell lithium batteries give the fact they have a chip that controls the charge status.?ÿ I'm not sure if each cell has the chip or just the battery pack.?ÿ Let me know what you find out, I have a couple of tools that you can not get batteries for anymore.?ÿ

There is almost always a way to re-cell.?ÿ If the manufacturers want designed obsolescence, then the battery case will be made so that it is very very hard to get it open unbroken

This...I own a 3dr solo for fun and the batteries are dying for everyone...so how do you recell a smart battery. The hardest part is that splitting the case results in no longer having a case...and that would fundamentally not work with a drill.

I have a big heavy dewalt 18v that I got on trade for a rifle scope a few years ago.

Borrowed a buddies light weight makita the other day. The smaller light-weight drills are so much easier to use.

I'd consider it a good excuse to upgrade.

I have several Dewalt tools that require 18v and 20v batteries. I got an adapter for the 20v to fit the 18v tools.

The 18v batteries appeared to have a fail rate of 1 out of 4 batteries and are being phased out.

The tools will work better with the 20v batteries that are improved and have better cells.

A few days ago I found a deal on Dewalt 20v batteries at Acme Tools. Two 5amp and Two 3amp batteries for $169.

They have package deals for many makes of tools on a regular basis and a deal for these batteries happens once every couple of years.

The newer brushless tools are way better, lighter and smaller.

good luck

Two 5amp and Two 3amp batteries for $169.

Maybe 5 amp-hour??ÿ The difference in units between amps and amp-hours is like the difference between miles per hour and miles.

@rundatline

I have looked at this and all of them have much smaller batteries with fewer amp hours of power.

@dmyhill  It is aggravating.  I am ending up balancing the cost of new with the cost of buying cells and printing my own cases.  If you don't have to deal with a new casing, it is kind of a no brainier given the cheap cost of the battery cells.  A lot of the time you can't reuse the hardware either, because you will damage it to much removing it from the existing case.  Do you know about this option?

@bill93

Thank you for mentioning that, they simply last longer

It does day 5AH and 3AH

Can also get tools and batteries that have variable power like 20v to 60v they call Flexvolt that will take on some serious applications.

Dewalt deal

Milwaukee deal

2nd deal

@just-a-surveyor

I don't know about you but I can't drill or screw for near as long as I used to anyway.
