although not official part it’s 100% compatible with even better capacity than official one. charges well and given roomba a new life (changed when said old batt was ok but only very charged to 99%). roomba now much better..

Dropped to run times of 55mins in 2 months that's the same as the 4 year old original it replaced. Think I will return it. Not a good alternative

Easy to swap and performance in line with what was promised.Buy Again - YESRecommend to a friend - YES

I bought this replacement battery because my original Roomba battery, that was a couple of years old, was starting to show signs of aging and the device was having to go back to the base station to recharge more and more frequently. This was getting to be a bit inconvenient as each job was taking 2-3 recharges where the same area used to be done on a single charge.I expected this "extended life" battery to be better than the OEM Roomba battery had been on day one, but even with supposedly significantly higher capacity, the Roomba only runs for maybe an hour before needing a recharge. This is hardly, if at all, better than the OEM battery that I bought it to replace.Although cheap I am considering buying a replacement Roomba branded battery, with its accompanying cost, as the convenience of doing the whole house on a single charge is worth it.

Great battery. It has extended the run time by a fair amount compared to the original.

This gave me the same amount of battery life as the original IRobot one - not the extra as advertised

its great
