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?
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.
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.
