Replacement Battery for RoboVac 11 Series

This 2600mAh lithium-ion pack delivers 14.4V and 36Wh of energy for compatible Eufy RoboVac models. It fits the 11, 11S, 11S MAX, 12, 15C, 15C MAX, 30, 30C and 35C units.

Who Should Choose This Pack

Owners of the listed RoboVac or Ecovacs Deebot N79, N79S, 600, 601, DN622 and 661 models gain a direct drop-in refresh. Buyers with a RoboVac 11+ or iLife A4, A4S, A6, A9, V7 series must select a different battery because the connector or cell layout does not match. Anyone needing a higher capacity than 2600mAh should look elsewhere.

The Deciding Specification

The 14.4V nominal voltage and 2600mAh capacity determine fit and runtime. If your original pack shows 14.4V and 2600mAh, this unit aligns electrically. A different voltage or milliampere-hour rating means the battery will not charge or run correctly in your robot.

Questions about this item

My Eufy RoboVac 11S MAX has model number T2126 — will this 2600mAh 14.4V Li-ion pack fit it?

Yes, the supplier lists the T2126 as a compatible RoboVac model for this replacement battery.

I still use an Ecovacs Deebot N79S alongside my new RoboVac — can the same battery work in both?

The battery is also listed as compatible with the Deebot N79S, so one pack type serves both devices.

After installing the blue 2600mAh pack, how do I know it is charging correctly on the dock?

Place the robot on a flat solid surface at the charging base; the unit should power on and begin charging normally.
