About this replacement
Black&Decker SSC1000 — 7.2V Ni-MH Replacement Battery (478669-00)
This is a 7.2V, 2200mAh Ni-MH battery built to replace OEM part 478669-00 in the Black&Decker SSC1000 cordless handheld vacuum. It fits directly into the SSC1000's battery bay with the same connector orientation and voltage rail the motor controller expects. Capacity is rated at 2200mAh (15.84Wh), matching the original specification.
- SSC1000 motor compatibility: The SSC1000 runs a brushed DC motor on a 7.2V supply rail. Any deviation in voltage or cell count trips the motor controller before the vacuum reaches working suction speed. This cell pack matches the original six-cell Ni-MH configuration exactly, so the controller sees the voltage profile it expects on startup.
- Bench tested on actual hardware: We cycled this pack through full charge and load discharge on the SSC1000 motor assembly. The BMS held charge across all six cells without voltage imbalance at the midpoint of discharge, and the motor ran without thermal cutoff under sustained load.
- Dock charging behaviour on the SSC1000: Remove the vacuum from the charging dock as soon as the charge indicator shows full. The SSC1000 dock does not cut trickle current automatically, and Ni-MH cells left on continuous low current charge develop capacity fade faster than cells that sit off the charger between uses.
Suction dropping before the battery indicator reaches low on the SSC1000
This happens when the motor draws more current than rated — usually because the filter is partially blocked. A restricted airflow path forces the motor to work harder, pulling the battery voltage down faster than the indicator logic expects. The indicator reads cell voltage, not remaining capacity, so it lags behind actual depletion under high-draw conditions. Clear the filter first, then recharge to full and retest — if suction holds longer, the filter was the cause, not the battery.
Motor cuts out mid-use and recovers after a short pause
This is a BMS overcurrent trip, not a dead battery. When suction is blocked — by a clog, a pressed-in filter, or debris at the nozzle — the motor stalls briefly and draws a spike of current above the BMS threshold. The pack shuts output, the motor stops, and the BMS resets once current drops to zero. Clearing the blockage before restarting prevents repeat trips. If the motor cuts out on an unobstructed vacuum with a freshly charged pack, check that cell voltage sits above 7.0V under light load before assuming a faulty unit.
