Replacement Battery for Ecovacs and Eufy Robots

The KingSener XJT-EC14-30 is a brand new nickel-metal hydride replacement battery designed for Ecovacs sweeping robots and Eufy RoboVac 30 units. It restores original runtime for compatible robotic vacuums that require a 14.4V power source.

3000mAh Capacity and Voltage Headroom

The 3000mAh capacity at 14.4V supplies the energy needed for typical cleaning cycles in supported robot models. Runtime will decrease as the cells age or if the robot operates continuously on high-power suction modes across large floor areas.

NI-MH Chemistry Defines Compatibility

This battery uses NI-MH chemistry, which determines its charge behaviour and physical fit. It is not suitable for devices that require lithium-ion cells or a different voltage, and it must only be installed in robots designed for this specific pack format.

Questions about this item

Will this 14.4V 3000mAh NI-MH battery work with my existing Ecovacs Eufy RoboVac 30 charging dock?

Yes, the KingSener XJT-EC14-30 is built to the same size and voltage as the original battery, so it fits the robot and charges on the standard dock without any adapter changes.

How can I verify the battery is performing correctly after I install it?

Fully charge and discharge the pack from low current two or three times; after that break-in the robot should run for its normal cycle length and the charge indicator should show a full 100% state.

What comes in the box and do I need to buy any extra cables or tools?

The package contains only the replacement battery itself; no charging cable, screwdriver or additional hardware is included, so reuse the connectors and tools from your original RoboVac 30.
