Roomba 80501 Battery Replacement (3000mAh) Rechargeable for iRobot Roomba 500, 510, 530, 532, 535, 536, 540, 550, 551, 562, 570, 572, 580, 590, 610, 760, 770, 780 Vacuum Cleaners

Had it for about a month. Works very well. Runs for more than an hour (don't know exactly, as never measured).One problem was with the initial installation. Got recharging error 1. Batttery not connected. Needed to bend the contacts to get it to work. Seems that this is a problem often with the original battery supplied by iRobot.[...]

I bought this for my 5 years old Roomba to extend its valuable life. The installation is easy and it works fine in my old Roomba. But almost at the same time, I also bought a brand new Roomba. Comparing this replacement battery with new Roomba, I can tell the huge difference: the new Roomba's battery can last over 2.5 hours without charging, but the replacement battery will only last about 45 minutes (in old Roomba) -- it only slightly beats my 5 years old battery (which still lasts 30 mins). So if I have to buy again, I will consider buying the Roomba brand with a little more money.

I think it was worth it for the price I paid It coast me 1/2 the price what I paid for it ,If was to have got it from IRobot company itwould have coast me twice the price I paid for it . Very happy the way it workbetter then I expected to work nealy 2-hours of run time compare to the old oneI had in there gave me only 25-mins of running timeVery happy with it.

Good price, quick delivery, now my Roomba can finish the hose without running out of power. Product was as described, and it is not an original replacement part but it works just as good in the old Roomba.

The battery, which I have had about two weeks, is already losing power, when I got it it would run about 1 hour and 5 mis, now it runs about twenty minutes. At this rate it will be dead in another week. It's not worth what I paid for it.Thank you for checking on it.Can I get a replacement or refund?

Battery works fine; price was great; but only get 1 hr and 15 minutes run time. With original battery I would get 1hr and 45 minutes. Wish I would have purchased a 3500 ma\hr battery though.

Doesn't seem to last as long as the original battery did, But at less than half the price it's still a good bargain.

I tried this battery rather than order from Irobot, which is more expensive. After charging it in my roomba, it definitely seemed to run well and much longer than my old battery.

Timely service. Product as expected

Great but!!

Thanks
