The OEM battery died after 6 months. I’m sure that an aftermarket battery would last as long, or better.This battery did not disappoint. It fit perfectly and has our Roomba i3 running like new.

It was bad upon receipt, would not hold charge. I replaced it with an iRobot battery and it works great.

works like original battery did. have only used it 6 times. I can't comment on longevity.

looks like and fits like the OEM, works fine. longevity is still to be determined.

All I have gotten from the seller is send an image.... no offer to replace or return.. it is a bad battery we need to return and get a refund.. we just ordered a battery directly from roomba this AM...

Claims 46Wh which is nearly double the capacity of the name brand replacement, but 80% cheaper. Even if the capacity claims turn out to be false, it seems just as good or better than the original so far. Installation was easy, it’s the exact dimensions as the original and came charge at around 80%.

It was great for 5 months. The extra capacity was enough to vacuum an entire first floor without recharging. However, it failed after 5 months and won't hold a charge anymore.

I'd like to say I was happy with this battery. It's fit my device just fine and everything was great for it seven months. Then nothing. It won't charge. I don't know why.I had my roomba for 3 years before the original battery failed. I'm going to purchase the original OEM part this time and see if it lasts longer than 7 months.
