About this replacement
Ecovacs Deebot DW700 Series — 12V Ni-MH Replacement Battery (H-SC3000P)
This is a 12V, 2500mAh Ni-MH replacement battery for the Ecovacs Deebot DW700 robotic vacuum cleaner. It fits the DW700, DW700-WR, DW701, and DS620 among others. Voltage and capacity match the original spec from the product data — 12V, 2500mAh, 30Wh.
- DW700 series compatibility: The DW700, DW700-WR, DW701, and DS620 share the same 12V Ni-MH pack format, connector pinout, and BMS communication protocol. Swapping between these models requires no modification — the same cell fits all.
- Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on a DW700 unit. The BMS accepted the cell without fault codes, completed charge termination at the correct delta-V threshold, and the robot resumed normal navigation and cleaning sequences.
- Dock charging discipline for Ni-MH cells: Ni-MH chemistry in robotic vacuums suffers faster capacity fade when left on the dock permanently. Once the DW700 completes a cleaning cycle and returns to charge, remove it from the dock after the charge light clears — do not use the dock as a storage stand between sessions.
Deebot DW700 losing suction before the battery indicator shows low
The DW700's motor draws peak current when fighting a partially blocked filter or restricted airflow path. A Ni-MH pack with even moderate capacity fade cannot sustain that current without voltage sag. The robot's BMS interprets the sag as low battery and reduces motor speed — suction drops even though the indicator still shows charge remaining. Clean or replace the filter first, then test again; if suction holds through a full cycle, the filter was the cause, not the battery.
DW700 motor cuts out mid-clean then recovers after a short pause
This is a BMS overcurrent trip, not a battery failure. When the suction path is restricted — blocked brush roll, clogged filter, or debris jam — the motor draws sustained current above the BMS threshold. The BMS cuts power to protect the cell, the robot pauses, and it restarts once the BMS resets. Clear the blockage and check that the filter is seated correctly. If the cutout continues on a clear path, measure pack voltage under load — it should hold above 10.8V during motor run.
