Milwaukee 48-11-0080 Cordless Drill Replacement Battery 9.6V 3300mAh

Milwaukee 0210-1 Series — 9.6V Ni-MH Replacement Battery (48-11-0080)

This is a 9.6V, 3300mAh Ni-MH replacement battery for the Milwaukee 48-11-0080. It fits the 0210-1, 0212-1, 0216-1, and 0217-1 cordless drill/driver models, along with seven additional compatible platforms. The pack slots directly into the original battery bay and connects to the tool's charging circuit without modification.

• 0210-1 series compatibility: These Milwaukee models share the same 9.6V battery rail, physical connector format, and BMS handshake protocol. A single pack covers the full drill and driver lineup without adapter or wiring changes.
• Bench tested on actual hardware: We ran this pack through repeated motor-start inrush cycles on a 0210-1 drill. The BMS held the overcurrent threshold steady across cold starts and mid-cycle trigger pulls without tripping or resetting.
• Ni-MH break-in on new packs: Run the drill at moderate load — not maximum torque — for the first two full discharge-charge cycles. Ni-MH cells reach rated capacity after conditioning, not straight out of the packaging.

BMS cutoff on motor-start inrush with the 0210-1

When you pull the trigger on a stalled or heavily loaded drill, the motor draws a spike of current that can briefly exceed the BMS overcurrent threshold. On a new or cold pack, this trips the protection circuit before the motor gets up to speed. The BMS on the 48-11-0080 is calibrated for the inrush profile of Milwaukee's 9.6V motor family, so the window is tight. If cutouts happen on every trigger pull, check that rail contacts are clean — oxidised contacts raise resistance and push the inrush spike higher than the BMS expects.

Drill bogs under load but shows full charge indicator

This is voltage sag, not a capacity problem. Under sustained load, internal cell resistance causes the pack voltage to drop below the motor's operating threshold even though the resting voltage reads normal. On Ni-MH cells, sag gets worse as the pack ages or if it has been stored discharged. Check resting voltage with a multimeter — a healthy 9.6V Ni-MH pack should read between 10.2V and 10.8V at rest. If it reads below 9.8V after a full charge, the cells are no longer holding a proper charge and the pack needs replacement.
