Makita CL104D Cordless Vacuum Replacement Battery 10.8V 1200mAh

Makita CL104D Cordless Cleaner — 10.8V Li-ion Replacement Battery (632C65-0)

This is a 10.8V 1200mAh Li-ion replacement battery for the Makita CL104D cordless handheld vacuum cleaner. It fits the CL104D directly and uses OEM part number 632C65-0. Voltage and capacity match the original factory specification.

• CL104D platform fit: The CL104D runs on Makita's 10.8V slide-pack format. This battery shares the same connector layout and BMS communication protocol as the original, so the cleaner's charge indicator and protection circuits behave as expected.
• Bench tested on actual hardware: We ran this cell on a CL104D unit and confirmed the BMS initialised correctly on first insertion. The overcurrent cutoff triggered at sustained motor restriction and reset cleanly once load was removed — consistent with factory behaviour.
• Dock charging on the CL104D: Do not leave the CL104D sitting on the charging dock continuously between uses. Sustained trickle current from permanent dock contact accelerates capacity fade in Li-ion cells at this capacity class. Charge to full, then remove the battery from the dock.

Suction dropping before the battery indicator reaches low

The CL104D's motor draws more current under load than under free-air conditions. When the filter is partially blocked, airflow restriction forces the motor to work harder, pulling the cell voltage down faster than the indicator circuit expects. The battery reads as charged, but the motor isn't receiving enough voltage to maintain suction pressure. Clear the filter and check the cyclone separator — restored airflow lets the cell deliver its rated current without voltage sag.

Motor cuts out mid-use then recovers after a short pause

This is a BMS overcurrent trip, not a dead battery. When the motor sustains a high-draw condition — usually from a blocked nozzle or clogged filter — current draw exceeds the BMS threshold and the circuit opens to protect the cell. The battery recovers once the BMS resets, which typically takes 15–30 seconds off load. Fix the blockage first, then reinsert the battery and confirm the cell sits above 10.0V at rest before continuing use.
