3200mAh 14.4V Li-ion Battery Replacement Battery with Deebot N79S DN622 Eufi RoboVac 11 11S 11S Plus MAX 15C 25C 30C 35C G10 R500 R450 Hybrid G30 etc. Cleaning Brush Included

Gave My Aging Eufy RoboVac a New Lease on Life!My trusty Eufy RoboVac 11S has been a part of the family for a few years, but recently I noticed it was struggling. The cleaning cycles were getting shorter and shorter, and it would often die before finding its way back to the charging base. I was about to start shopping for a whole new robot vacuum, but decided to try replacing the battery first. This Maxlithium replacement battery was a perfect match, and I'm thrilled with the results.Installation Was a Breeze:Swapping out the old battery for this new one couldn't have been easier. It took less than five minutes and only required a small Phillips head screwdriver. The battery compartment on the bottom of the Eufy is easy to access. This replacement battery was the exact same size and shape as the original, and the connector clicked into place perfectly. It was a true plug-and-play installation.Performance & Runtime Restored:The difference in performance was immediate and dramatic. After an initial full charge, I sent the RoboVac on its way. Where it was previously running for maybe 45 minutes, it now runs for well over an hour and a half, easily cleaning my entire main floor on a single charge with power to spare. It's like having a brand new vacuum again. The 3200mAh capacity seems to be a genuine upgrade over the stock battery.A Nice Little Bonus:The included cleaning brush was a thoughtful addition. It has a hook on one end for pulling hair off the roller brush and bristles on the other for dusting out the filter and collection bin. It's a small thing, but it's genuinely useful for routine maintenance.Final Verdict:If your robot vacuum isn't holding a charge like it used to, don't replace the whole unit! This replacement battery is an affordable and incredibly effective way to restore its original performance. The installation is simple, the runtime is excellent, and it has saved me from a much more expensive purchase. This is an easy five-star recommendation for anyone looking to bring their hardworking robot vacuum back to its former glory.

works great!

Worked for 5 months and then stopped charging. Messaging the seller to see if they will replace under their warranty. - update: the seller offered a full refund and replaced the battery for free. The new one is working like a charm and hopefully it continues to do so. This seller stood behind the product and helped when the first one failed

I noticed that our Eufy robovac wasn’t working its usual 60 minutes, so I replaced the battery. Sadly, the replacement had a quite short lifespan. It stopped working immediately even after an overnight charge! I realized that I needed a much-higher capacity battery. After a quick exchange to this battery, the vac was up and running better than brand new! The time is extended to a full 90+ minutes thanks to this battery! I have had to recall it back to base when it has done the entire downstairs floor! This battery is a perfect fit and definitely worth the cost!

Update: the seller reached out and refunded my order after my negative experience. This seller is very fair.Purchased Feb 2024, by Jan 2025 we have had multiple battery errors and have almost had to replace this battery multiple times. I feel like it should last longer than a year and I don’t like receiving the battery error notifications.This was easy to install. We use our robot 2-3 times a week for reference. We get an error that this battery won’t charge once a month or every other month.

It's weird Amazon would require a rating for longevity on a battery one just received. Having said that, this battery has our vacuum working like new, and has run for about 5 or 6 cycles (uses) so far. In fact, I think the run time is longer than with the original battery. It goes a good 90 minutes, now. Installation was easy, so we'll see how long this battery lasts for the long run. I will try to remember to update in about a year.

I have a Eufy G30 edge. Original OEM battery had a run time in excess of 100 minutes. After three years, it had deteriorated to about 40 minutes. I bought this as a replacement. I charged it overnight and tried it out. It had a runtime of 48 minutes. I repeated the cycle of charging and running two more times with the same result. I thought I had a defective battery so I contacted Amazon who then replaced the battery for me. I repeated this charging and running process with the second replacement battery only to find that it had a runtime of 50 minutes. So now I am less convinced that I had a defective battery, and more convinced that this is just a poor substitute for the OEM battery. I do not recommend this battery.

got my eufy robot vac going again
