Midea R1-L102B Robotic Vacuum Replacement Battery 14.4V 2000mAh

Midea R1-L102B / R1-L10D — 14.4V Ni-MH Replacement Battery

This is a 14.4V, 2000mAh Ni-MH replacement battery for the Midea R1-L102B and R1-L10D robotic vacuum cleaners. It fits the motor and navigation power rail directly, restoring the cleaning cycle after the original cell has degraded. Capacity is 2000mAh (28.8Wh), matching the factory specification.

• R1-L102B and R1-L10D compatibility: Both models share the same 14.4V power bus, connector form factor, and battery bay dimensions. The cell fits either unit without modification.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the R1-L102B platform. The BMS accepted the cell without fault codes, and the motor draw across hard floor and carpet transitions stayed within rated current limits.
• Dock charging habit for Ni-MH cells: Do not leave this vacuum sitting on the charging dock indefinitely between uses. Ni-MH chemistry is more vulnerable to trickle-charge damage than lithium. Charge to full, then remove from the dock until the next cleaning cycle.

Suction dropping before the battery indicator reaches low

On the R1-L102B, the motor controller reduces power output when pack voltage sags — this happens earlier than the low-battery indicator triggers. A partially clogged filter forces the motor to draw above its rated current, which accelerates voltage sag on any cell, including a new one. Clean the filter before fitting a replacement battery. If sag still occurs early, check that the cell terminals are making firm contact in the bay and that resting voltage reads at least 16.8V after a full charge.

Motor cuts out mid-run then restarts after a few seconds

This is an overcurrent trip, not a flat battery. When suction is restricted — blocked brush roll, saturated filter, or tight carpet pile — the motor pulls a sustained current spike that the BMS reads as a fault and interrupts. The pause you see is the BMS resetting. Clear the blockage, clean or replace the filter, and run the unit again. If trips continue on an unobstructed floor, the cell itself may be supplying current unevenly due to cell-level imbalance — a fresh replacement will resolve that.
