Rowenta N047-4S2P Replacement Battery 14.4V 6700mAh

Rowenta RG7975WH/NS0 Series — 14.4V Li-ion Replacement Battery (N047-4S2P)

This 14.4V, 6700mAh Li-ion battery fits the Rowenta RG7975WH/NS0 cordless stick vacuum and several models in the same family. It replaces OEM part numbers N047-4S2P and SS-2230002529. Capacity figures are taken directly from product specifications — 96.48Wh total energy.

• RG7975, RG7987, and RR7935 platform: These models share the same 14.4V motor rail, physical connector, and BMS handshake protocol, which is why a single cell pack covers the full range. Voltage tolerance across the platform is tight — swapping in a mismatched pack will trigger an immediate BMS lockout at power-on.
• Bench tested on actual hardware: We cycled this pack through sustained motor-load draws on the RG7975 platform. The BMS held stable across repeated start cycles and did not trip under the inrush current the motor pulls at startup. Cell voltage at full charge measured consistently at the rated 14.4V nominal.
• Dock charging behaviour on this vacuum: The RG7975 dock does not cut power when the pack reaches full charge. Leave it docked continuously and the cells sit under a constant trickle that accelerates capacity fade. Charge to full, remove the vacuum from the dock, and replace it only when the pack is depleted.

Suction dropping before the battery indicator reaches low

This happens when the motor draws more current than the BMS allows under restricted airflow. A partially blocked filter forces the motor to work harder, pulling sustained current above the BMS overcurrent threshold. The BMS responds by throttling output voltage to the motor — which the user feels as lost suction — even though the pack still has charge remaining. Clean or replace the filter first, then retest suction at a measured distance from the floor to confirm the issue is airflow-related rather than cell degradation.

Motor cuts out completely then recovers after a few seconds

A momentary full cutout that self-recovers is a BMS overcurrent trip, not a dead battery. It typically occurs when the vacuum hits a carpet pile or blockage that stalls airflow and spikes motor draw above the pack's continuous discharge limit. The BMS shuts the output, waits for the overcurrent condition to clear, then resets automatically. Check the brush roll and inlet for partial blockages — if the cutouts persist on open hard floor with a clean filter, the replacement pack needs to be bench-verified at 14.4V under load before returning the vacuum to service.
