Can you use 18 volt batteries in 14 volt Dewalt tools?
 

I need to buy new batteries for my little drill and was wondering if I can use the 18 volt batteries in the 14 volt drill I know they will fit but will they burn it up? The reason is the 18 volt batteries come in a two pack for $100 and the 14 are $85 each?

18 volt batteries shouldnt fit the 14v drills. there designed to not fit so you wont burn up the drill. i have both and the 18v batteries dont fit

I "fit" 14.4's on my 12v, I've been doing it for the past 10 years, never had a problem.

I'd imagine you can do the same thing

ugh, throw the dewalt out and get a real tool

Care to name a few "real" tools that the average "joe" or homeowner can afford? Not the pros out there, just us weekend handymen..

I have both Dewalt and Rigid cordless drills. The Dewalt was given to me without batteries and I purchased the two pack at Home depot. Works fine and is in my tool box now. Would I buy one if I had to pay full price? No as I have a Rigid 1/2 inch chuck lithium powered hammer drill that can handle much more. The Rigid batteries have a lifetime warranty. The Dewalt batteries do not. The Rigid is available at Home Depot from their Reconditioned sales for only $110.00. http://www.homedepot.com/h_d1/N-5yc1...atalogId=10053 That is a deal that is unbeatable.

Rigid like shorebird says. Although I do find them heavy but I haven't seen the lithium ion ones yet. I still run panasonic drills and they are my favorite but are pricey.

I put an 18 volt battery on the gutted circuitry and motor of a 12v drill, and the transistor that actually drives the motor burned out and popped instantly. I can't imagine a 14v transistor on that drill lasting much longer then the 12v one.

My Dad has one of those Makita Lithium Ion drills, a lot of power for its size, and very compact and well balanced. Battery does not last that long, but it only takes 15 minutes to charge.
