Rowenta RR7 Replacement Battery 14.8V 2600mAh Li-ion

Rowenta RR7 Series — 14.8V Li-ion Replacement Battery (RS-2230002091)

This 14.8V, 2600mAh lithium-ion battery replaces the original pack in the Rowenta RR7 robotic vacuum cleaner. It fits the RR7 series including RR7747WH4Q0 and RR7755WH4Q0 variants. OEM part numbers RS-2230002091 and 6.32.40.13-0 cross-reference directly to this cell configuration.

• RR7 series fitment: These models share the same 14.8V four-cell Li-ion architecture, connector pinout, and BMS communication protocol — so one cell pack covers the full RR7 line without modification.
• Bench tested on actual hardware: We ran this battery through charge and discharge cycles on the RR7 platform. The BMS correctly negotiated with the dock charger, accepted a full charge, and delivered stable voltage through motor start and navigation load transitions.
• Dock charging discipline on RR7: Do not leave the RR7 on the charging dock permanently. Continuous trickle charging accelerates capacity fade on this cell pack faster than on most cordless vacuums due to the dock's constant-contact charge circuit. Charge to full, then remove from dock.

Suction dropping before the battery indicator reaches low on the RR7

This is one of the most common symptoms with a degraded RR7 battery. As internal cell resistance rises with age, voltage sags under the motor load of a partially blocked filter or dense carpet pass — even when the battery gauge still reads mid-range. The motor controller interprets that voltage sag as a load problem and reduces fan speed to protect itself. Check the filter first, but if suction recovers on hard floors and not carpet, the cell pack is the cause.

Motor cuts out mid-cycle then recovers after a pause

This is a BMS overcurrent trip, not a motor fault. When suction is restricted — by a blocked filter, full dustbin, or brush roll tangle — the motor draws sustained current above the BMS threshold, and the pack shuts the output to protect the cells. The RR7 pauses, the BMS resets after a few seconds, and the robot restarts. Clean the filter and brush roll, then check that the dustbin is seated correctly. If trips continue on a clean machine, verify the replacement pack is reading at or above 14.4V resting voltage before reinstalling.
