These tool batteries fit Milwaukee cordless tools of a matching voltage and platform (e.g., M12 batteries for M12 tools, MX FUEL batteries for MX FUEL tools, and V18 batteries for V18 tools). Battery series are interchangeable within a platform. For example, an M18 tool can use any series of M18 battery (CP, XC, or HD). CP series batteries are lighter than XC and HD, so they’re used with drills, nailers, and when working overhead. XC series batteries have more power than CP and are used for circular saws and other high-draw tools. High-demand (HD) series batteries are used with heavy-demand tools such as chain saws and table saws. High-output versions of Milwaukee batteries have more power, run cooler, and are smaller and lighter than standard versions. Batteries of the same voltage, platform, and series may be available in different amp-hour (Ah) ratings. Batteries with higher Ah ratings have greater power storage capacity but are heavier than those with lower Ah ratings.

These tool batteries fit DEWALT cordless tools of a compatible platform and matching voltage. For example, a 20V MAX* battery works with 20V MAX*, MAX* XR, and Atomic tools. MAX XR* batteries are premium batteries with more capacity than standard MAX* batteries. MAX* Compact batteries provide the runtime of standard MAX* batteries in a lighter, slimmer form. FLEXVOLT batteries fit 20V MAX*, 60V MAX* and 120V MAX* tools (which require two FLEXVOLT batteries). They automatically switch voltage to match the power of the tool they are paired with, and they provide extended run time for 20V tools. The battery capacity listed for FLEXVOLT batteries is the amp-hour (Ah) rating when operating at 20V. This capacity is reduced when operating at 60V. Batteries of the same voltage, platform, and series may be available in different Ah ratings. Batteries with higher Ah ratings have greater power storage capacity but are heavier than those with lower Ah ratings.

These tool batteries fit Makita cordless tools of the same voltage and series. For example, a 12V CXT battery will work with a 12V CXT tool and an 18V LXT battery will work with an 18V LXT tool. 18V X2 (36V) LXT tools operate on two 18V LXT batteries. Batteries of the same voltage and series may be available in different amp-hour (Ah) ratings. Batteries with higher Ah ratings have greater power storage capacity but are heavier than those with lower Ah ratings.

These tool batteries fit Bosch cordless tools of the same voltage and a compatible series. For example, a 12V Max battery will fit Bosch 12V Max tools and an 18V Max, CORE, or SlimPack battery will fit any series of Bosch 18V Li-Ion tools. CORE series batteries provide longer run times and more power than Max and SlimPack series batteries. SlimPack series batteries have more power than Max series batteries and are lighter and more compact to help make large tools easier to handle. Batteries of the same voltage and series may be available in different amp-hour (Ah) ratings. Batteries with higher Ah ratings have greater power storage capacity but are heavier than those with lower Ah ratings.

These tool batteries fit Greenlee cordless tools of the same voltage and a compatible series. Greenlee 18V batteries are made by Makita and are used to power Greenlee's Gator series tools. Batteries of the same voltage and series may be available in different amp-hour (Ah) ratings. Batteries with higher Ah ratings have greater power storage capacity but are heavier than those with lower Ah ratings.

These tool batteries fit Fein cordless tools of the same voltage and any series. For example, an 18V tool can use a standard or HighPower series 18V battery. HighPower series batteries provide higher output power than standard series to power heavy-duty tools such as magnet core drills and angle grinders. Fein 12V batteries can also be used on Fein 18V tools that have a MultiVolt interface. Batteries of the same voltage and series may be available in different amp-hour (Ah) ratings. Batteries with higher Ah ratings have greater power storage capacity but are heavier than those with lower Ah ratings.
