Can You Interchange Batteries On A Cordless Drill?

Posted · Report post

I have a 14.4v cordless drill with a dead battery (it won't recharge). I went to Lowe's and they didn't have the 14.4v batteries, just 12v and 18v. Do any of you know if I can run the drill safely on a 18v battery?

What about the 12v? Will it not me give enough power, or will it damage the motor too for not running on the proper volts?

My dewalt wouldn't run with a lower volt battery. It needs to be the correct voltage.

Dont forget to check the type of battery also, that is the most important

. The different types are

Ni-Cad (nickel cadmium)

NiMH (nickel metal hydride) most common and being phased out for next type

Li-Ion (Lithium Ion)

A regular 18v NiMH battery is less powerful than a 14v Li-ion, so look at the cost of a new Li-ion drill before spending money's on a NIMH battery. For example, you might be able to get a 14v Li-ion drill for $60-$90 as opposed to a 14.4v NiMH that could cost $45. Prices have come down on batteries and Internet will be best place to get the best price, but just consider switching to new more powerful and longer lasting Li-Iom if it's not a lot more money.

I personally bought the Hilti 14.4v Li-Ion impact drill and it's half the size of my Hilti 18V NiMH, half the weight, has LED light built into tip that light when you press trigger, it lasts at least 50% longer than 18v, and is a little bit more powerful. Hilti is lot more expensive than other brands and you can get a Bosch or Milwaukee with same Li-Ion technology and same feature for a fraction of the price of Hilti

Stalking my posts Phil? I saw a question and read Mr."eat a dick's" bullshit answer and go to pawn store advice and decided to give the OP a real answer! Replacing a 14.4 v with a 12v will NOT burn it up. Because of the progression of batteries, 99.9% 14.4v NiMH drills won't accept the tooth arrangement of the 18V. If you do find one of the few exceptions dewault / black and decker drills that do, they should still be ok as long as there are 2.0 amp and not 3.0 amp or higher.

Check out if your town has a Batteries Plus place. They can perform a "Flush" on old batteries that can save some of them. They can also get just about any bettery you need.
