I have owned an i robot for at least 6 years maybe more. Every year i have to order a new battery. This year someone told me that i can now get batteries on line without going through Irobot. I am so grateful this battery was 1/3 the cost and works even better ( so far) runs longer by about 30 minutes. I love my irobot but was ready to just throw it away becasue of the continual costs. Thank you Amazon, i can now afford to keep it in batterys.

Battery is even beter then OEM as, for the price, it has a higher capacitor rating which runs longer and chargers in less time. Shipper stated that it would arrive in 7-14 days, it arrived in 5 days!

I had a bad battery in my irobot, and this was a perfect replacement after six years. The robot is back up and running, and I think this battery may actually last a little longer than the original one did when I bought it.

This battery doesn't hold a charge much longer than the old one we replaced. The next one will come directly from the company. Don't waste your money.

I have owned at least 5 Roombas, and their weakest point has always been their battery. I was leery about buying a non-OEM battery, but I have to say that this one is better than any I've ever received from iRobot. It ran longer right out of the box than any other battery I've ever owned for my Roomba's. I'd buy this again.

A good battery at a good price. Roomba really Rumbas now. Would buy from this person again when they have something I need.

It works well. I do hate how they simply die after long periods of not using them, but as long as you use your robot often and and keep it charged everything goes good.

Installation was fantastic, but it only charged the Roomba one time. My initial delight has turned to dissatisfaction. I can't decide whether to invest in one from the manufacturer or throw it away.

Bought this battery on the strength of the written reviews and it was shipped quite rapidly. Out of the box the battery was not able to be charged and not usable, despite 2 days of charging...buyer beware!

The Roomba runs for about 5 minutes and dies with the new battery. I guess that is an improvement over the old dead battery. Anyway, I'm giving up on the roomba altogether and not wasting money on another battery.
