Ecovacs Dibea K6L 14.4V Replacement Battery 1800mAh Ni-MH

Ecovacs Dibea K6L / ZN101 Series — 14.4V Ni-MH Replacement Battery

This is a 14.4V, 1800mAh Ni-MH replacement battery for the Ecovacs Dibea K6L robotic vacuum and compatible models including the L6, ZN101, and Dibea K6. It powers the drive motors, suction fan, and onboard navigation during cleaning cycles. Swap it in when the original cell no longer holds enough charge to complete a full floor pass.

• Dibea K6L, L6, ZN101 and K6 platform: These models share the same 14.4V motor rail, battery bay dimensions, and connector pinout. One battery cell covers all of them without modification.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on a Dibea-platform unit. The BMS held cutoff correctly at low voltage and accepted charge from the stock dock charger without fault codes.
• Dock charging habit on Ni-MH cells: Do not leave the K6L sitting on the charging dock indefinitely between uses. Ni-MH chemistry degrades faster under continuous trickle charge than Li-ion does. Charge the robot to full, then remove it from the dock until the next cleaning session.

Suction dropping before the battery indicator reaches low

The K6L's suction fan motor draws significantly more current when the filter is partially blocked or the brush roll is restricted. That extra draw causes the battery voltage to sag under load before the cell is genuinely depleted. The onboard indicator reads state-of-charge at rest, not under load — so it still shows green while the motor is already starved. Clean the filter and check the brush roll for hair wrap before assuming the battery is at fault.

Motor cutting out mid-cycle then recovering after a few seconds

This is a BMS overcurrent trip, not a dead battery. When sustained suction restriction forces the motor to pull above the battery's rated continuous discharge current, the BMS cuts power to protect the cell. The pack resets itself once internal temperature drops, which is why the vacuum restarts on its own. Clear the filter, empty the dustbin, and check for blockages in the intake path — then confirm the battery resting voltage reads above 12.0V before assuming the cell needs replacement.
