Ecovacs Deebot Deepoo X600 14.4V Replacement Battery 1800mAh

Ecovacs Deebot Deepoo X600 Series — 14.4V Ni-MH Replacement Battery

This 14.4V, 1800mAh Ni-MH battery replaces the original power cell in the Ecovacs Deebot Deepoo X600, ZN605, ZN606, and ZN609 robotic vacuum cleaners. It fits the same battery bay and connector as the factory unit. Capacity is rated at 25.92Wh, matching the original specification.

• X600, ZN605, ZN606, ZN609 compatibility: These four models run the same 14.4V drive platform, use an identical battery bay footprint at 101.66 x 43.78 x 29.85mm, and share the same BMS voltage thresholds — so one cell fits all four without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Deebot platform. The BMS accepted full charge without fault codes, and the protection circuit tripped correctly at the low-voltage cutoff threshold during deep discharge testing.
• Dock charging habit for Ni-MH cells: Ni-MH chemistry is more sensitive to trickle charge damage than Li-ion. Do not leave this robot sitting on the dock permanently between cleans — charge to full, then remove it. Continuous dock contact accelerates capacity fade in Ni-MH cells faster than occasional deep discharge cycles.

Suction dropping before the battery indicator reaches low on the X600

The X600 motor draws significantly more current when airflow is restricted — a partially blocked filter or clogged brush roll forces sustained high-draw operation. Under that load, a degraded Ni-MH cell shows voltage sag well before the battery gauge registers as low. The robot interprets the voltage drop as normal operation until the BMS cutoff triggers unexpectedly. Clean the filter and check the brush roll before attributing suction loss to the battery.

Motor cuts out mid-clean then recovers after a short pause

This is a BMS overcurrent trip, not a dead battery. When sustained suction restriction forces the motor to draw above the BMS overcurrent threshold, the protection circuit shuts the cell output and resets after the internal temperature drops. The robot resumes because the BMS resets, not because the fault is cleared. Check the filter and inlet path first — if airflow is unrestricted and cutouts persist, measure resting voltage after a full charge; a healthy 14.4V Ni-MH pack should read between 16.5V and 17V fully charged.
