So far, I like everything. I have concerns about longevity, so we'll see.

The battery worked fine over 1.5 years. A little after that, my Roomba begun stopping randomly with the battery completely discharged. Mistakenly believing that it was only half a year since I bought the battery, I contacted customer service asking for replacement. Customer service rep corrected me, saying that my battery is over 1.5 years old, and... sent me a brand new battery! Considering that the warranty for the battery is 1 year, I really do appreciate the gift. So, here is my opinion: decent battery, great customer service! Thank you.

So far the battery has been working in our Roomba 900 series. I haven't had any real issues with the battery it was easy to install and it fits the model perfectly. I think it may have taken me may 2 minutes to change out the battery. However, it does seem like it doesn't hold as much of a charge as the OEM battery. The OEM was pretty old, probably close to 4 years now. I remember when we first got the original and it would run for almost 90 minutes. This battery doesn't seem to run longer than 60, if the job takes longer than that it needs to go back and recharge. Overall its not a bad purchase for the price and it works for what I need it for.

It fits perfectly and works terrific. Took all of two minutes to change out the battery. Just two screws. Put the Roomba on charge overnight and it’s been perfect ever since.

I bough this battery because of the high reviews it received, and it worked well for about 5 weeks. Then one day it wouldnt charge anymore. I cleaned the contacts on the vacuum, and the charging stand, but it didn't help. I put the original Roomba battery back in, and it charges and runs the vacuum. I will send this back, since I am within the return window. Overall I am very disappointed with the outcome.

It drops right in. No problems charging. I've cleaned about three times so far with no issues.

Battery installation was easy and fits perfectly. However the expectation of 2 hours runtime was not observed in my 980. The roomba runtimes are 45 minutes either on carpet or wood floor. I tried resetting / rebooting and had no issues with connecfivity or error messages and followed the instructions.My old battery was from 2016 original and my reason for replacing was 30 minute runtime and wouldn't finish a room. I may return to see if a new battery behaves differently.Had some issues but seller was able to help me sort it out and now getting -2hrs run time!!

It was easy to install and is holding up well, so far.
