Replacement Battery for Milwaukee M12 Tools

This 12 V lithium-ion pack delivers 3.5 Ah of capacity and fits the Milwaukee M12 cordless system. It replaces original part numbers such as 48-11-2401, 48-11-2420 and 48-11-1815. The red-and-black housing matches the OEM colour scheme. It is supplied new and ready for immediate use.

Suitable for M12 Drill, Driver and Impact Owners

The cell works with M12 drill drivers including the 2401, 2402, 2403 and 2404 series, M12 impact wrenches such as the 2451 and 2452, and M12 inspection cameras like the 2310 to 2314 range. It also powers M12 fork meters, clamp meters and laser scanners listed in the compatibility data. Users of M18 or higher-voltage platforms cannot use this pack.

3.5 Ah Capacity at 12 Volts

The decisive figure is the 3.5 Ah rating at 12 V, which determines run-time per charge for every compatible tool. No other capacity or voltage variant is described in the data. Buyers needing a different amp-hour value must select another battery.

Questions about this item

How do I confirm the 12V 3.5Ah battery is working after installing it in my M12 tool?

Insert the pack into a compatible M12 tool such as the 2401-20 drill or 2451-20 impact wrench; the tool should power on and run normally, indicating the 3500mAh cells are delivering correct voltage.

What comes in the box and do I need to buy a charger separately?

The package contains only the 12V 3.5Ah lithium-ion replacement battery; a compatible Milwaukee M12 charger such as the 48-59-2401 or 48-59-1812 must be purchased separately if you do not already own one.

Which capacity should I choose between the 3Ah and 3.5Ah versions listed?

The 3.5Ah (3500mAh) version provides longer runtime per charge than the 3Ah variant while fitting the same M12 tools and chargers, so choose 3.5Ah for extended use.
