Batryuic's upgraded 4000mAh 14.4V N79 replacement battery restores and extends runtime for compatible Eufy and Deebot robot vacuums.

If your RoboVac or Deebot is stopping sooner than it used to, this Batryuic replacement battery offers a high-capacity, safety-certified option to get more cleaning time between charges. Designed as a direct swap for models using the 3-prong N79 connector, the pack delivers long run times, built-in protection circuits, and thousands of recharge cycles so your robot vacuum returns to dependable performance.

How much longer will my robot run with this 4000mAh battery?

The Batryuic 4.0Ah pack increases available energy, typically producing 120–180 minutes of continuous operation on a full charge depending on your vacuum model and its condition. HEavier cleaning patterns or older motors reduce runtime, while lighter modes extend it.

• Typical runtime: most models around 2 hours on standard settings
• Varies by model: RoboVac 11/11S/30 series and Deebot N79/N79S see the largest gains
• Real-world factors: floor type, suction mode, and brush wear affect minutes
