iRobot Roomba 1800 Lithium Ion Battery

I was thinking of just getting a new vacuum robot to replace my Roomba 960 and I'm glad I didn't. I was a little upset when I saw that Roomba 980 batteries cost only a fraction of the price of the 960 replacement battery, but I really think it's worth the price.Of course it very easy to install. The first couple times you charge it, it takes a really long time, more than 12 hours.After those initial charges, it only takes like 2 hours to charge. On a single charge, my Roomba will run for about an hour and 20 minutes.Another issue I was having was my Roomba 960 wouldn't return to the charging station. It would always stop about a foot away from it and have the error beep every 30 seconds or so until I picked it up and out it on the charger.I was hoping a new battery would fix it but it didn't.So I found a YouTube video of a guy explaining the solution. He said to pop out the front castor wheel and put a washer on the metal part that connects the castor wheel to the Roomba. This will raise up the front of the Roomba very slightly. I'm not talking about the two main wheels, but the one front and center that rotates in all directions. After applying this fix, the Roomba now returns to it's base station with no issues!!I'm really pleased with everything now and glad I didn't waste money getting a newer fancier robot vacuum. I'm hoping my 960 lasts for several more years before I need to replace it.

I recently replaced the battery in my iRobot vacuum with the iRobot 4502233 Robot Vacuum Battery, and it’s been a great choice! As an OEM part, it’s built to high standards and works perfectly with my vacuum. The battery holds a charge well, ensuring that the vacuum can clean my home thoroughly without any interruptions. It’s reliable and easy to install, giving my vacuum a new lease on life. This battery is also a perfect replacement for the 900 series vacuum. Highly recommended for anyone needing a dependable replacement battery for their iRobot vacuum!

The battery died before 2 months, I returned it and purchased from the company.

My original died in my 960. I tried a generic battery that cost a little less. It didn't work as well, would not go home to charge and just plain sucked. I switched back to the original brand and my machine was like new again!! Will never use generic in this machine again!!

I bought this battery by mistake and Amazon promptly accepted my request for product return. So there are five stars to Amazon customer service.Though the battery itself - I am not sure why they are selling it while there are 3.3A battery available from IRobot but was not available at Amazon. I have three IRobot vacuum cleaners in my house and I know that at least in my environment 1.8A is not sufficient capacity. So I really do not know how to properly rate it.Service - 5startsBattery in itself is probably OK (I have not tried but I assume works well)But why they do not offer larger capacity battery ?

Perfect fit

I received an opened package with a battery that was clearly not OEM, didn't say iRobot anywhere on the battery and not what was pictured online. The battery was defective out of the box, not able to charge or hold a charge. Completely disappointed and returning for replacement. Should I receive the correct OEM battery that works, I will ammend this review.

I was going to buy a cheaper third party battery, but sprung for the real deal given all the bad reviews. This battery fixed my roomba and hold a good amount of charge for each use. So far it’s worth the money! Hopefully it lasts at least a few years, as this was a cheaper alternative to buying a whole new robot.
