Update: The company graciously replaced the first battery, because it was weak, the replacement battery is a total rock star. The replacement came in May, it is now September and the replacement battery is still running strong. I have raised the rating from 4 to 5 stars because the replacementbattery is holding out very well, more so due to the great customer service we received. Thank you. The first one of these batteries became very weak just after 2 months. I was unable to contact this seller and so was Amazon. I left a very candid review talking abut how great the battery started out and how quickly the battery had gone bad. Let me say, Amazon stood behind me and that was very appreciated.The seller contacted me a couple of days after my review had been left. They said it sounded like a cell or more had gone bad and that they woukd send me a new battery. I explained that Amazon already made it right, but this company wanted to wipe the egg off of their face as well. They sent me a brand new battery. For now I am giving 4 stars for the first battery failing and the awkwardness of how contacting them was. If this battery turns out to be a Rockstar, I plan on raising the stars to 5. We will have to wait and see.

I rarely give negative comments since I understand doing business is difficult in these days. But this seller does not answer message through Amazon Customer Support. So far 3 messages have no reply.The battery ran around 40 minutes (new, January 2024) and dropped to around 30 minutes in the summer, when I still thought it is ok... the time works for me! But the deterioration went faster and I started to send messages to the seller, because in their product page, it was listed replaceable within a year. In short, now the battery totally died (Dec. 2, 2024). So I can only say, this seller is not responsible and the product is bad!

Easy to replace the old battery, and the roomba now runs more than 2 hours instead of 30 minutes. Schedule is to run every day, and it does. I would buy it again, probably WILL, as I have 3 roombas (all same series as the upper series require frequent beater bar replacements ($$) )

Easy to install, high voltage (looked a lot before I bought this one). Our robot floor vacuum cleaner could no longer clean the full room and return to the charger before it was done.I got this battery, and fully charged it before the first run, and "poof", did the whole room (it does have to return to the charger to get the rest of the room, but the battery did its job.Easy to install, and works perfectly!

I replaced the original battery in my Roomba 980. When new, the original battery would go about an hour.This battery goes 90 minutes with some power left. Pricing was great and I think this is a good value.

I read many of the reviews on this battery, and saw how a good number of them claimed the battery wasn't up to the job. Because of the price alone, I chose to believe the positive reviews and go ahead and get one. I've had this battery for about six weeks.Unfortunately, this battery hasn't been able to power my roomba in order to complete a single run. Every morning it's like an Easter Egg hunt to find where my roomba ran out of juice. Surprisingly that little round sweeper is pretty good at hiding. I'm tenacious so I'm able to find it each time and place it back on the charger, ready to play the game the next time it tries to run.I know some folks claim to have success after purchasing this battery. My guess is they have a small area for their roomba to sweep and have no way of noticing how lacking its power really is. Best advice I can give, bite the bullet and buy an OEM battery, like I'm about to do.

This thing right away didn't last long. It would need recharged within 15 minutes of starting to run. Today, it ran a whole 4 minutes.Don't get this particular replacement, it will not last.

Bought two of these, both were installed in Roomba 800 series models.I am having an issue where the battery refuses to charge after use. The robot flashes a red charging warning and never charges.They seem to have trouble charging when the voltage is too low.

Works like a champ.

I bought two batteries and one of them stopped working after four weeks, while iRobot was used just 4-5 times.

It is a very common issue I see I have the same problem with it dying after 4-5 minutes, replaced all the Roomba accessories and then sticking it on the charger for it to recharge in a very short period but is not actually charged based on its next run for a few minutes.

Battery performance is not great, I was expecting an upgrade and therefore paid too much!
