Unfortunately, this battery does not my Roomba to work as long as the original. Result, he longs for the entire 4 small residential rooms but already looking the dock just entered the third. So I have to suck in 2 times (and be there, which is really not the purpose of a Roomba). In short, I will have to buy another battery ... I thought that one month (I have not changed right after purchase) it calibrerait and autonomy increase. But no ... The former would surely have better battery life!
