What to say ... These batteries are original ones and my Neato XV15 regained its original perfs. Besides, I strangely have a slightly greater autonomy. But here, I think those were not original top. They had necessitated several operating cycle to get them a proper autonomy. Ms on new batteries, this is not the case. I had enough to make my 80m from the first load. In short, very satisfied, I have only one regret, that Neato have not used lithium-ion battery, but this ... This is a different story.
