20 Volt to 60 Volt 9 AMP hours Battery


The dual-voltage 20V/60V MAX* FLEXVOLT® 9.0 Ah battery automatically changes voltage when you change tools, providing up to 6X runtime** in 20V MAX* tools and the power of corded in 60V MAX* and 120V MAX* tools. Take on tough jobs with this battery because patented technology and large format cells mean it runs cooler*** than the leading competitor 9.0 Ah battery pack under a constant discharge. This is the battery for FLEXVOLT® power and long runtime.

Dual Voltage for Ultimate Flexibility

DEWALT DCB609 9AH Battery Cell More Runtime

*Maximum initial battery voltage (measured without a workload) is 4, 20, 60 and 120 volts. Nominal voltage is 3.6, 18, 54 and 108. 120V MAX is based on using 2 DEWALT 60V MAX* lithium-ion batteries combined.



DEWALT DCB609 9AH Battery Runs Cooler

On average, the Milwaukee® 48-11-1890 Battery temperature rises 50% faster during a constant 60 amp discharge up to a 70°C thermal shutdown.

    DEWALT® Battery meaning of Suffixes on Kits

    For DEWALT, all cordless tool kits and combo kits use a letter sequence to identify what battery comes with the kit followed by a number telling us how many batteries come with it.
    An example would be DCF895M2, the “M” tells me it includes the DCB204, the number 2 tells us it has 2 of them.
    If this is also followed by a “BT” like in DCF888P2BT it means the battery is Bluetooth enabled.
    The exception to this rule is a “B” suffix, like DCB996B. This letter tells us it is a bare tool, meaning tool only, no battery, charger, or kitbox/bag.
    Current suffixes are:
    B = bare tool
    C = DCB201 (1.5 AH)
    D = DCB203 (2.0 AH)
    L = DCB200 (3.0 AH)
    M = DCB204 (4.0 AH)
    P = DCB205 (5.0 AH)
    R = DC206 (6.0 AH)
    T = DCB606 (6.0 @ 20V and 2.0 @ 60V)
    X = DCB609 (9.0 @ 20V and 3.0 @ 60V)
    Y = DCB612 (12.0 @ 20V and 4.0 @ 60V)
