Our CELLONIC replacement Eufy batteries bring your vacuum cleaner back to full power, saving you money while helping to invest in a sustainable and eco-friendly future.

100% compatible with Eufy batteries

Check out the full compatibilities list.

True 3400mAh capacity

What makes our batteries different? When we state 3400mAh, that’s exactly what you get. Competitors often claim capacities for batteries that are in fact far, far lower. This battery has a true capacity of 3400mAh - exactly as advertised.

High-performance BFG-WSQ, ICR18650-26J-4S1P battery

Our replacement RoboVac 15C batteries deliver consistently high performance, power and suction, and runtimes that match or exceed that of your original vacuum cleaner battery - for a high number of charging cycles.

Superior quality and safety standards

Battery specialists since 2004, all our replacement batteries undergo strict and rigorous testing throughout the whole production process, complying with the highest standards and beyond. That’s why they come with a 3-year warranty.

The sustainable choice

Replace the battery, not your vacuum cleaner. It’s the smarter, cheaper, eco-friendlier choice, cutting your environmental footprint through recycling and reducing unnecessary waste.

Choose CELLONIC and never compromise on quality. Order now!
