I own a Milwaukee 14.4V NiCd cordless drill. The batteries appear to be on their last legs. I’d like to buy a couple of Lithium-ion batteries to replace the NiCd. However, while not exhaustive, I did a search and it appears to me that Milwaukee does not offer a 14.4V Li-ion battery. They do sell an 18V. My question is: Is it ok to operate what was sold as a 14.4V drill on an 18V battery? If it is ok, am I correct that I will have to buy a new charger for the 18V battery even though it will fit on the charger that came with the 14.4V batteries?

I do not think you can use a 18V battery in a 14.4V Drill. See what others say.

This question comes up at least once a month on this site.
Even if Milwaukee made Lithium batteries for the cost of just two Lithium batteries (and charger for them) you can buy a whole new cordless drill with lithium batteries and charger included. Sears has some good combinations….even though I am partial to Porter Cable. Watch for sales and check the manufacturers web sites for discounts.
It is a sad state that new batteries cost that much. It makes the drill a disposable tool. By the way be sure to dispose of those old NiCd batteries at a recycle center.

no you cant it’ll fry your cordless 14.4 tool’s motor.

I agree with LesB – it’s a sad market that the batteries control sales. I sold all my dewalt cordless tools (10 of them) because all my batteries reached their end of life, and it just isn’t cost effective to get new batteries – I replaced the tools that I needed with a corded version.

BUT – one company that is worth mentioning on this subject is Ridgid – if you buy their tools, and you’re the original owner – you get batteries for life! I wish they all did this.

Thank you Tom, Les and Sharon. I do have a relatively inexpensive option. HD sells a replacement 14.4 NiCad battery for $59 and I might even find it cheaper elsewhere, say at Amazon. So for just $50 or so, I prolong the life of a tool I have really liked. Granted, it isn’t “up-to-date” ala Lithium ion, but it is a fine, functional tool. I received a $50 gift certificate from one of my outlaws (oops), I mean in-laws recently so it’s sort of like I am not really putting out the money. I also own a Ryobi Li-ion 4 tool combo set and that drill is my first drill of choice but you know how convenient it is to have that second drill when you are drilling countersink holes and filling them with screws. I did not know about the Rigid policy. That sounds like a very enticing deal. I will have to explore their product line.

You can try to revive your worn out ni-cads with this method.

I’ve tried it and saved the batteries on my Porter Cable drill. I used a battery charger and the batteries work like new.

Check out the on line sites for batteries. I bought 2 XRP 14.4 V DeWalts from an on line seller for less than the cost of just 1 at my borgs.

Beware of web sites that claim to “recondition” or rebuild batteries. It appears all they do is “shock” charge the batteries to get a little more life out of them. I haven’t tried it but people who have say they don’t last long.

Steer clear of Craftsman batteries and chargers from Sears.I foolishly bought a second higher voltage set after the 9.6V set failed , only to end up with the same lousy battery life and next day charger that came with them. I’m still using my PC and DeWalt drivers after nearly 15 years . I discovered the “shock therapy” method of resurrecting the batteries a few years ago . However , I used my auto battery charger instead of a welder to revive the cells. I don’t recommend this procedure to anyone that is not mechanically inclined though.You could get hurt if not careful and although it worked on most of my batteries , some of the individual cells were too far gone and need to be replaced. I will go with RIDGID if my present tools fail me.
Best wishes Lenny , and be safe : )
PS: I’m sure that Milwaukee has made their 18V battery incompatible with the 14.4V mounting area to prevent “accidents” from occurring. Peace : )
