My eufy robovac 12 battery died, so I replaced it with is one and so far the battery is lasting considerably longer .

It worked straight out of the box

Purchased to replace the one in my robo hoover. It doesn't last as long as the original, but it works and that's all that matters.

Item as described

eems to be working well and with a long life

so understanding battery capacity et cetera quite disappointed actually that it doesn’t last as long that’s what I would hopeful given it has had multiple charges so it should be up to capacity, however fitment is the same no issues with that at all

I am using this replacement battery in my Eufy Robovac 30 Max C. In boost IQ mode it serves around 1hr 5 mins in my flat in which the floor area is mixed of carpet and wooden flooring. It’s little better than my old battery which was dying but it’s no where close to what is claimed. I.e 3 hrs.

The original battery for my Deebot N79s lasted at least 90mins (70mins on max power) and was rated at 2600mAh. This one was rated at 3500mAh only lasted 70mins (50mins on max power). So basically the battery works but just not up to what was advertised. Could be that I got a faulty unit.Update (08/11/23)Returned and bought another one. Have used it for almost 2 weeks now and still the same. Works but not to the capacity advertised. It could be I got another lemon but taking away another star for inconvenience.
