The new heart was well accepted by our dear Dobby (Roborock S6maxV), the operation was carried out without any problems and took less than 15 minutes.

He is now sucking again, healthy and lively, and is still not out of breath even after 1:30 hours on the second-highest setting.

The product works properly. But the small tab on the connector arrived broken. I hope it won't come loose. The delivery was fast. As time goes by I will be able to check the quality of this battery. Thank you.
Brigitte from on 23 Aug 2024

The battery fits well, the replacement is no problem but the robot hoover stops despite the battery replacement and can no longer find the charging station. We thought after 4 years it must be the battery.
Zeynep from on 26 Oct 2025

Thanks to the new battery, my robot is vacuuming/mopping at full speed again. I love it again and again and recommend it to everyone in my circle of friends.

Perfect for my first-generation Xiaomi vacuum cleaner

It’s working as it should again. My Roborock S502-00 vacuum cleaner. And they’ve met the deadline they gave. I’m satisfied.

Description

Our CELLONIC replacement 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 batteries

Check out the full compatibilities list.

True 5200mAh capacity

What makes our batteries different? When we state 5200mAh, 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 5200mAh - exactly as advertised.

High-performance 400-900-1755 battery

Our replacement 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!

Das neue Herz wurde von unserem lieben Dobby (Roborock S6maxV) gut angenommen, die Operation erfolgte ohne Probleme und dauerte keine 15 Minuten.

Er saugt nun wieder gesund und munter, und ist auch nach 1:30h auf zweithöchster Stufe noch nicht ausser Atem.

El producto funciona correctamente. Pero la pequeña pestaña del conector llegó rota. Espero que no se suelte. La entrega fue rápida. Con el paso del tiempo podré comprobar la calidad de esta batería. Gracias.

Der Akku passt gut der Tausch kein Problem aber der Saugroboter bleibt trotz Akku-Tausch stehen und findet die Ladestation nicht mehr. Wir dachten nach 4 Jahren müsste es der Akku sein.

Dank dem neuen Akku saugt/wischt mein Roboter wieder in voller Länge. Immer und immer wieder gerne ich bin unendlich begeistert und empfehle es jedem im Freundeskreis weiter.

Received as expected, replacement in place of the original. First charge and recovery of initial autonomy, remains to be seen over time.

Product conforms, hoping that the battery will perform well over time. Not like the one I bought on a Chinese site.

Produit conforme en espérant que la batterie sera performante dans le temps. Pas comme celle que j'avais acheté sur un site chinois

The hoover’s working like a dream again. Brilliant suction power, and the battery lasts for ages again. Unbeatable value for money!
