Replacement Battery for Ecovacs Deebot

This 14.4 V lithium-ion pack replaces the original XJT-2P4S-6800 and XJT-2P4S-7800 cells used across the T5, T8, T9, T10, T20, X1, DX and DLX robot families. It also fits Yeedi vac, vac max and vac 2 pro units. The black housing matches the factory colour scheme. Buyers whose robots use a different voltage or connector will need the correct alternative.

Thermals Noise and Power Draw

Lithium-ion chemistry delivers steady 14.4 V output with minimal self-heating during normal cleaning cycles. The pack operates silently inside the robot chassis and requires no active cooling. Capacity remains stable across repeated charge cycles when stored at room temperature.

Capacity Decides Fit

Rated at 7800 mAh, this unit supplies more runtime than the 6800 mAh and 5200 mAh variants listed in the cross-reference table. Select this model only if the service manual specifies 7800 mAh for your Deebot or Yeedi serial number.

Questions about this item

How do I install the XJT-2P4S-7800 battery in my Ecovacs Deebot T8 Aivi, and which step is often missed?

Power off the robot, remove the battery cover screws, disconnect the old pack, connect the new 14.4V 7800mAh unit, refit the cover and screws, then place the robot on the dock for a full initial charge before first use.

What maintenance or replacement will the KingSener XJT-2P4S-7800 need over time?

The Li-ion pack needs no scheduled servicing; when run time falls well below the original 7800mAh capacity after extended cycling, replace the battery with another XJT-2P4S-7800 unit.

What is the first limit that appears during sustained cleaning with this 14.4V 7800mAh replacement battery?

The runtime ceiling set by the 7800mAh capacity is reached first; once the charge depletes the robot must return to its dock to recharge before continuing.
