    Get what you pay for.

    Ordered at this price. It's been 9 months and it's not charging anymore. If you look at the charging process for 1.5 hours, the charging time is almost 4 hours. And it hasn't changed since day one. I would avoid this and use Roomba lithium-ion batteries. Update: I changed 1 to 3 stars. The battery is not my problem. The base charger is defective. This gives loading error 15 if someone else has problems. I bought another iRobot base and it's working fine again. The battery still doesn't last…

    • Certified

    • Cable is shorter than other picks

    Perfect upgrade/replacement

    *update* Added photo of cleaning time. In fact, the cleaning process of the old battery takes about 30 minutes longer. Highly recommended. I've had a 960 for about 4 years. Do it 2-3 times a week. Replace normal parts about 2 times a year as expected. However, you can tell that the battery doesn't last that long. I bought it to replace and give it extra time while running and it actually added 20 minutes to the run time. My house is 75% tile but when I first lit it up with a new battery it…

    Good replacement battery

    Bought a Roomba 960 in 2018 as a Christmas present. The original battery could never fill an entire house without recharging. It started out lasting about 45 minutes. I found it takes about 1.5 hours to complete building the entire house. We replaced the original battery in the first half of May 2021. Back then, the original battery life was reduced to around 25 minutes, which will last around 6.5 hours. to complete the whole house, but in most cases Roomba died before he could return to the…

    • Quick replacement

    Started out as a great battery but didn't last long. Too bad

    Updated on 03/13/2020: Dropped to 2 stars. In the last 30 days, there have been constant loading errors. Can't charge this week. The month worked great. . I had to take the battery out every day to reset and recharge it. Now it doesn't load at all. When it worked it was great. Whether the problem is the Tempe battery or something Roomba does to only use genuine parts, I can't deal with it. I tend to think so, but... I just got here yesterday. I will update if anything changes. Bought for Roomba

    So far so good for vacuuming and floor care

    First I ordered two different batteries which said they were 4500mah and got a lot of good reviews but the run time on both was no better than the first. a well used 6 year old battery which I replaced. I have a charger that can measure actual battery capacity and the ones tested are only around 2000mAh which is less than half of the advertised capacity. I should have known given the low price, but I was fooled by the positive reviews. Then I decided to try this Tenergy pack and ordered a pair…

    • Delivery was very quick
    Cons
    • Crumpled
