Will these fit my DeWalt 12V drill?

They are listed for DeWalt 12V Max tools and cross-referenced to DCB120, DCB121, DCB127, DCB100, DCB101 and DCB119. The model list includes DCD700 and DCD710 drills, DCF610 and DCF815 impact drivers, DCS310 cut-out tools and DCR006 speakers. Check your tool's model number against that list before buying.

Are these genuine DeWalt batteries?

No. They are third-party replacement packs made to fit DeWalt 12V Max tools. They carry a one-year warranty from the seller, not DeWalt's own coverage.

How does 3.0Ah compare with the battery that came with my tool?

Many DeWalt 12V Max kits ship with 1.3Ah or 1.5Ah packs. At 3.0Ah these roughly double the runtime per charge, at the cost of a little extra weight and longer charging.

Three 12V 3.0Ah lithium-ion battery packs and a user manual. No charger is included.

Can I leave them on my DeWalt charger?

Use a charger made for DeWalt 12V Max lithium-ion packs. As with any lithium-ion pack, take it off the charger once it is full rather than storing it charging for long periods.

Our take on the DeWalt DCB120 12V 3.0Ah Lithium Battery Replacement 3-Pack

A three-pack of 12V lithium-ion replacement batteries for DeWalt's 12V Max cordless tools, cross-listed against OEM part numbers DCB120, DCB121, DCB127, DCB100, DCB101 and DCB119. Each pack battery is rated 3.0Ah, which is more capacity than the 1.3Ah and 1.5Ah packs DeWalt ships with many 12V drills, drivers and cut-out tools, so runtime per charge is longer. They are third-party packs, not DeWalt-branded, and come with a one-year warranty. Buyers who already own several 12V Max tools get the most from a three-pack, since one charger and one battery platform covers drills, impact drivers, oscillating tools and inspection cameras.
