Similarly one may ask, are 18v and 20v DeWalt batteries interchangeable?
Dewalt's “20V Max” cordless power tool line is not at all compatible with their 18V line, except for their multi-port vacuum.
Also, can you use a 24v battery on a 18v drill? Using 18V cordless tools on 24V battery bank. The 24V is a bit bore than the tools were designed for so it may wear on the tool a bit more but the batteries are around 20V fresh of the charger and you are going to see a bit of voltage drop in your new cables especially with stall currents of around 40A.
Similarly, you may ask, can I use a 20v battery in a 12v DeWalt drill?
Standard DeWalt 20 volt batteries are compatible with all 20-volt tools, as well as all 20-volt chargers. DeWalt 20v MAX batteries can't be used in FlexVolt 60v and 120v MAX tools, however. The lower voltage doesn't provide enough juice for the high-demand motors.
Can you use 18v battery in 14.4 V drill DeWalt?
The 18v battery wont fit in the 14.4 tool(I just tried it). It will if some modifications are made to the 14.4V Tool. My 18v dewalt charger will charge a range of packs from dewalt (so the label says). I used jumper wires to charge various 12v packs from B&D and Skil.
