Compatible Milwaukee 28V replacement battery

This lithium-ion pack delivers 4 Ah at 28.0 V for Milwaukee M28 and V28 cordless tools. It replaces original part numbers including 48-11-2830 and 48-11-2850 across hammer drills, impact wrenches, saws and angle drives. The cell chemistry matches factory specifications for direct fit and communication with the tool electronics.

Black rugged housing with slide-on mount

The 133.00 x 79.60 x 82.40 mm casing slides onto the tool rail and locks with the original latch mechanism. Contacts align with Milwaukee 0721-20, 0721-21, 0726-22 and 0780-20 models as well as Wurth Master H 28-MA and BS 28-A Combi units. No adapters or modifications are required for the listed devices.

112.00 Wh capacity with standard Li-ion discharge

The pack supplies consistent current for drilling, driving and cutting tasks without voltage sag under load. Internal protection circuitry guards against over-discharge, over-current and short-circuit conditions during normal operation. Heat dissipates through the housing surface during extended use cycles.

Questions about this item

What 28 V Milwaukee tool interface does this 4 Ah Li-ion pack fit?

It fits the M28 and V28 slide-on battery rails used on tools such as the 0721-20, 0726-22, HD28 series and Wurth Master 28V models.

Will the 133.00 x 79.60 x 82.40 mm black housing latch into my existing M28 charger and tool bay?

Yes, the pack matches the original M28 form factor so it seats and locks in the same charger and tool receptacles.

How do I install the pack without triggering the protection circuit on first use?

Align the contacts, slide the pack onto the tool until the latch clicks, then give it a full charge before the first heavy draw.
