Questions about this item

How long will the 2600mAh capacity actually run my robot vacuum?

The 2600mAh / 36Wh rating at 14.4V gives the energy store; real run time depends on the robot model, floor type, suction setting and battery age.

What does the 14.4V rating mean for compatibility with my RoboVac?

The pack delivers 14.4V nominal; it is built as a direct replacement for the original battery in the listed Eufy and Ecovacs models, so the voltage matches the robot's charging and protection circuitry.

Will this blue pack fit inside my Deebot N79S without modification?

The A26-4S1P is moulded to the same form factor as the factory battery for the N79, N79S, DN621 and DN622, so it seats in the original compartment and uses the existing connector.
