DM20DC12 Battery Adapter: DeWalt 20V & Milwaukee 18V to DeWalt 12V
DM20DC12 Battery Adapter: DeWalt 20V & Milwaukee 18V to DeWalt 12V
DM20DC12 Battery Adapter – Convert DeWalt 20V or Milwaukee 18V Li-Ion Batteries to DeWalt 12V/14.4V Ni-CD/Ni-MH Tools
Breathe new life into your older DeWalt 12V and 14.4V Ni-CD/Ni-MH power tools without buying new batteries. The DM20DC12 Battery Adapter lets you plug in your modern DeWalt 18V/20V/60V or Milwaukee M18 18V lithium-ion battery packs directly into tools that previously required legacy nickel-cadmium or nickel-metal-hydride packs — giving you longer run time, lighter weight, and the convenience of a battery ecosystem you already own.

Frequently Asked Questions
Q: Will the DM20DC12 adapter work with my DeWalt 20V MAX DCB204 battery?
A: Yes! The DM20DC12's lower interface is compatible with DeWalt 18V/20V/60V lithium-ion batteries, including the DCB204. Simply slide your DCB204 into the adapter's lower slot and connect the upper interface to any compatible DeWalt 12V/14.4V Ni-CD or Ni-MH tool body.
Q: Can I use a Milwaukee M18 48-11-1850 battery with this adapter on a DeWalt 12V tool?
A: Absolutely. The adapter's lower interface accepts Milwaukee M18 18V lithium-ion packs such as the 48-11-1850. The upper interface then connects to your DeWalt 12V/14.4V Ni-CD or Ni-MH power tool, letting you use your Milwaukee battery in older DeWalt tool bodies.
Q: Do I need to keep the adapter on when charging the battery?
A: No — always remove the DM20DC12 adapter before charging. Use a dedicated, compatible charger for your specific DeWalt or Milwaukee battery pack. Charging through the adapter is not supported and could damage the battery or adapter.
Q: Is the adapter compatible with DeWalt 18V Ni-CD or Ni-MH tools?
A: No. The upper interface of the DM20DC12 is designed specifically for DeWalt 12V and 14.4V Ni-CD/Ni-MH tool bodies only. It is not compatible with 18V tool bodies or lithium-ion-only tool platforms.
