Dewalt has announced a new FlexVolt 20V/60V Max 15.0Ah Li-ion battery, model DCB615.

This is the highest capacity battery Dewalt has ever launched as part of their 20V Max of FlexVolt cordless power tool systems.

Dewalt press materials describe the types of users and applications they have in mind for this new battery:

Delivering a new threshold of performance in the FLEXVOLT Battery lineup, the 15.0 Ah battery is designed to provide maximum runtime in heavy-duty commercial applications including concrete and masonry, metalworking, building, and remodeling.

The battery is compatible with all Dewalt 20V Max (and FlexVolt) chargers.

Dewalt says it can be used in outdoor temperatures as low as 0°F.

The battery has a 3-LED fuel gauge.

Price: $349
ETA: September 2021

Dewalt has also announced two new 60V Max brushless SDS Max combination rotary hammers, which they say are ideal pairings for the new FlexVolt 15.0Ah battery. Read more about Dewalt’s new 1-7/8″ (DCH735) and 2″ (DCH775) rotary hammers here.

Note: 15Ah is measured in 20V Max mode, which is in line with how Dewalt’s previous FlexVolt products were described.


It shouldn’t come as any surprise that Dewalt launched a new 15Ah battery, especially since the same cells are presumably used in the 10Ah batteries that launched with their new cordless lawn mower.

What will see next – compact 5Ah batteries?

Dewalt has so far announced two new rotary hammers that they describe as being ideal tools for use with the new battery. What other high performing tools do you think are on their roadmap?
