Do these fit all Milwaukee M18 tools?

Yes. They are standard M18 packs and work with the full M18 cordless lineup, including drills, impact drivers, saws and lights.

How do these compare with High Output batteries?

High Output packs use newer cells that deliver more power in high-draw tools like circular saws. These XC5.0 packs are the standard extended-capacity option and cost less for comparable runtime.

Is a charger included?

No. The box holds two 5.0Ah battery packs only, so you need an M18 charger you already own.

How long do they run compared with compact packs?

Milwaukee rates REDLITHIUM for up to 2.5X the runtime of standard lithium-ion packs. In practice, expect roughly double the runtime of a 2.0Ah compact pack in the same tool.

Do the packs work in cold weather?

Milwaukee builds them to handle tough weather, and owners report they keep working in cold conditions, though capacity drops in freezing temperatures like any lithium-ion pack.

How do I check the charge?

Press the fuel gauge button on each pack; the LEDs show remaining charge in quarters.

About the Milwaukee 48-11-1852 M18 REDLITHIUM XC 5.0 Battery 2-Pack

This is a two-pack of Milwaukee M18 REDLITHIUM XC5.0 extended capacity batteries, model 48-11-1852. Each pack is an 18V, 5.0Ah lithium-ion battery for Milwaukee M18 cordless tools. Milwaukee rates the REDLITHIUM line for up to 2.5X more run-time, 20% more power and 2X more life than standard lithium-ion batteries.

REDLINK Intelligence manages communication between the battery, tool and charger to help protect against overload. The batteries also have discharge protection to help prevent cell damage over time. The heavy-duty pack construction protects against vibration, drops, heat and tough weather, and the design routes water away from the electronics and out of the pack.

Each pack has an onboard fuel gauge that shows the remaining charge. The batteries are compatible with 250+ M18 cordless solutions. Milwaukee's M18 & M12 Rapid Charge Station can charge them.
