Keenstone Replacement Battery for Eufy RoboVac 11C, 2600mah Li-Ion Rechargeable Battery, Compatible wit Eufy RoboVac 11 11C 11S MAX RoboVac 30 30C 35C 12 15T 15C 15C MAX Conga 990 DEEBOT N79S N79

Not listed as a compatible replacement, but this is rated the same, and has the same connection as the old battery I took out. Previously the vacuum was barely managing 10 minutes of cleaning (after around 3years of use) and with the battery replaced it’s back up to about an hour. Easy to replace, unscrew the battery compartment screws, unclip the old battery connector (needed needle nose pliers), then clip in the new one and close it up. Charged for about 16 hours before the programmed cleaning time. Happy as it’s much cheaper than buying a whole new robot. I can restart my cancer cure research 🔬 (or just go back to being too lazy to vacuum the floors myself)

Easy to fit, works well, an easy upgrade to a 4 year old Eufy unit

Easy to install

As per the title, it’s slightly thicker than the original so needed a firm push (eufy 30c). Old battery was no longer holding charge. New battery initially seemed excellent however noticed the hoover will show a red light during charging instead of pulsing orange. Needs to be turned off and on and will start charging again.Comes with a decent warranty so will monitor for a bit before requesting a refund should it persist.

My vac began stopping after about 30-40 minutes of cleaning and failing to return home.New battery and it’s back to being like new! Full 70+ minute clean and remembering to return to base to charge and get ready to go again!Can’t comment on the longevity of the battery since it’s only been a week, but so far so good!

I would say this is a long term review, but it really isn’t. Fitted in our 30c 21st February and it was great. The Eufy (we call her Debbie) was back to working for a full 90 minutes. Actually on day 1 it somehow lasted much longer. Excellent stuff! However by now, April 3rd the battery doesn’t last 23 minutes before conking out and now it tells me it needs a further 5 hours. In all, probably not worth skimping on the cheaper battery.

Replacement for Eufy robot vac. Easy to install. Works fine but don't know what the life will be. Cheaper than ordering from Eufy

Used this to replace my old battery on my 30C. Was easy to fix and worked well. Definitely lasts longer than the older one I replaced and less low battery warnings from the Eufy app - off course that’s an unfair comparison.It was easy enough to fix, easier than taking the old and dying original one out.

Giusta batteria per il mio robot

Très pratiques pour mon aspirateur robot. Longévité impeccable

After 1 year of use the robot is struggling to keep more than 20 minutes and to reach the charger afterwards. It's alright but not great quality.

Perfetto. Come l'originale.
