About this replacement
Philips FC6162 Series — 12V Ni-MH Replacement Battery (69-2008-009-202)
This is a 12V 1500mAh Ni-MH replacement battery for the Philips FC6162 and FC6162/02 cordless handheld vacuum cleaner. It replaces OEM part number 69-2008-009-202. The cell pack matches the original voltage, connector, and physical dimensions of the factory battery.
- FC6162 and FC6162/02 compatibility: Both variants run the same 12V motor rail with the same connector and cell housing. The BMS expects a Ni-MH cell pack at this voltage — swapping in a different chemistry or voltage causes the charger to reject the pack entirely.
- Bench tested on actual hardware: We cycled this pack through full charge and load discharge on a test rig matching the FC6162 motor draw. The BMS completed charge termination correctly and held voltage above the cutoff threshold under sustained suction load.
- Dock charging behaviour on the FC6162: Do not leave the vacuum sitting on the charging dock indefinitely. The FC6162 charger applies a trickle current when docked and full — continuous trickle charge accelerates cell degradation in Ni-MH packs. Charge to full, then remove from the dock.
Suction dropping before the battery indicator reaches low
Ni-MH cells under sustained motor load can sag in voltage before the battery gauge registers a problem. On the FC6162, a partially blocked filter forces the motor to draw more current to maintain airflow — this amplifies voltage sag and causes the motor to slow down visibly. The battery itself may still have capacity remaining, but sustained overcurrent pulls the pack below the motor's effective operating voltage. Clear the filter first; if suction recovers immediately, the cell pack is not the fault.
Motor cutting out mid-use and recovering after a short pause
This is a BMS overcurrent trip, not a dead battery. When the FC6162 motor encounters a blockage or heavily restricted airflow, current draw spikes past the BMS threshold and the pack shuts the circuit. After a short rest the BMS resets and the vacuum powers on again. Clearing the filter and checking the nozzle for blockages resolves most cases — if the motor trips immediately on a clean filter, the cell pack has degraded and can no longer deliver the required burst current. Replace the pack if trips continue after cleaning.
