About this replacement
Rowenta RH8827WO/2D0 Series — 24V Ni-MH Replacement Battery (RD-ROW24VA)
This is a 24V, 2000mAh Ni-MH replacement battery for Rowenta cordless stick vacuums, including the RH8827WO/2D0, RH8827WO/2D2, RH8828, and RH8828WO/2D0, among 83 additional compatible models. It replaces OEM parts RD-ROW24VA and RS-RH4900. Fit this battery when the original no longer holds a charge or the vacuum loses suction well before the indicator reads low.
- RH8827 and RH8828 platform compatibility: These models share a common 24V motor rail, battery form factor, and connector pinout. The BMS handshake across this range is consistent, so the same cell pack works across all listed variants without modification.
- Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the RH8827 platform. The BMS responded correctly to motor-start current draw, held voltage through the mid-cycle range, and tripped at the expected low-voltage cutoff without premature shutdown.
- Dock charging habit on Rowenta stick vacs: Do not leave this vacuum on the charging dock permanently. Ni-MH cells in this format develop capacity fade significantly faster under continuous trickle charge. Charge fully, then remove from the dock until the next use.
Suction dropping before the battery indicator reaches low
On the RH8827 and RH8828 series, the motor draws more current when the filter is partially blocked. That increased draw accelerates voltage sag in the battery pack, causing the motor to lose speed well before the charge indicator signals a problem. The indicator reads state of charge at rest voltage — not under load — so it lags behind what the motor is actually experiencing. Clean or replace the filter first, then test under load to confirm whether the issue is filter restriction or genuine cell degradation.
Motor cuts out mid-clean and then recovers after a short pause
This is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked filter, clogged nozzle, or heavy carpet pile — the motor draws sustained current above the BMS threshold. The pack shuts down to protect the cells, then resets once the overcurrent condition clears. Clear the blockage, wait 30 seconds for the BMS to reset, then restart the vacuum. If the trip repeats on an unblocked vacuum, check that the replacement pack voltage reads at least 24V off the charger before reinstalling.
