12/31/2021 Update: It’s been almost 2 years now and this battery is still giving me 1.5 hours of cleaning time. We are down to one Roomba now and have it clean 900 sq/ft 4 times a week. It just finished a job today where it ran for 1 hour 35 mins on a single charge cleaning the entire 900 sq/ft. We were on vacation for a month and the roomba got stuck. It went dead and sat for 3 weeks. I thought the battery would be unrecoverable as it wouldn’t charge giving me an error 8. I took out the battery, let it set for an hour and then put back in and placed back on the charger. It charged the battery and has the same battery life I had before. Can’t complain!6/28/2020 Update: I have 2 Roomba 980’s both with this battery and very pleased with them. They have been 5 mos since my last purchase and 8 mos since the prior. Both batteries are running in 980’s and the battery over time has increased cleaning time. I’m consistently getting 1:45 on each of them before needing a charge and has been holding steady. The key for me was performing the full reset on the robot and then remove/replace the batteries. After going through a number of poorly made replacement batteries, I finally found some that last.2/21/2020 Update: Replaced the battery in my second Roomba 980 last month with another Melasta. I reset the Roomba to defaults and did the battery remove/replace. I’m consistently getting 1:20 to 1:30 mins out of it. Quite happy with these batteries.11/11/2019 Update: Resolved the 60 minute recharge by resetting my Roomba to defualts and then pulling the battery and putting it back in. Now Roomba runs for about 1 hour & 20 mins prior to needing to recharge and this with all of the default settings. In regards to the torn tape handle, it really is not an issue, just a quality thing. Melasta reached out very concerned with it offering to send me replacement tape plus sent instructions on how to replace it. Definitely giving Melasta an "A" for their proactive support!!!Original Review: After 2 weeks of using this battery, the performance is right where I would expect it to be. I have a Roomba 980 and when I replaced my old battery, it was not lasting more than 10 minutes even with the most eco friendly options. In order to make sure I was getting the most out of the new battery, I performed a full reset on the Roomba and configured as a new device leaving all of the settings at default (Power Boost, Auto Cleaning Passes, Edge Clean...). I have a mix of about 60/40 carpet/hardwood floors and after 2 weeks, the Roomba will run for 60 mins and return to the base for a charge. Seems like maybe a limit on the Roomba to run for 60 mins and then return to base to charge, but that is just a guess.The battery fit is much like the oem and if I had one thing to complain about is the tabs to pull the battery out. They are like a piece of thin duct tape folded over. Works fine but mine came with a little cut in one of them at the battery edge which didn't change anything, but hope it doesn't become a future issue. I will monitor this battery for another month and update this review.

I’m one to admit, when it comes to my Roombas, I usually always go with OEM parts because they seem to just work better. However, I took a chance as I was hoping to find a battery that would last longer to clean a larger area. This battery was exactly what I needed! First, based on many of the previous reviews that explained how to replace the battery, I was able to get my 960 up and running in about 5 minutes. I would say my 960 now cleans about 10-20% faster! Additionally, the battery was over 50% after completing its job that was 1 hour and 11 minutes. I would estimate the battery will likely last a little over 2 hours in total.To be clear, like other reviews, factory reset your Roomba BEFORE you remove the old battery. Replace the battery, I added a small piece of cardboard between the battery and the battery door cover, then perform a hard reset again. Set up your Roomba and you should be good to go!The value for the money is fantastic. I cannot comment on longevity of the battery and keeping battery capacity as I just got the battery but I will try and report back.6 months update:Still doing great, no errors. No decline in performance or run time!

I bought another brand and it died after three cleanings, I mean completely dead, zero volts after charging for hours. This one works pretty good!

This is a much bigger capacity battery than the original battery on my 960. The original battery started running out and thebroomba would be dead on the floor before it could reach the charger and recharge.This battery dropped in and was an easy replacement. The problem comes up with charging. I believe it’s because the capacity on this batttery is so much greater than the original battery, the charger would run for a while and then give up because the battery was taking too long to recharge. I’d then get a battery error and would have to take it off the dock and put it back on to get the charger going again.This also happened the first 5-6 cleaning cycles, where I would get a battery error that cancelled that days schedule.It’s been about a week and a half, I factory reset the roomba, had the battery error appear once more, and it’s gone now. Everything works as it should so far, and it definitely has a much better cleaning capacity.Given the issues with it at the beginning, and the work it took to fix them, I can’t give it full stars, but it definitely appears to work as advertised now, so it’s a good price for a little initial headache.We will see how well it survives the rest of time.... well that was quick. The battery continues to come up with a charging error despite multiple attempts to reset it. This was a good idea, but it failed badly. Time to return the product. My guess is poor quality control or they need to do a better job of testing compatibility with different models of roomba

So this is the 2nd replacement battery iv bought for my Roomba 969. Iv had it for over 6 years and still runs strong. my first upgraded battery i bought a couple of years ago and it finally died. I bought this one because it is an upgrade to my upgrade. I was hopping for even longer battery life. Well it worked as advertised right off the bat, and then about the 4th cleaning I started to get the "Charging errors, and low battery life". I thought it was my charging base, but after readings reviews there is a smart guy that says the battery is "short" and its slides down away from the contacts in the compartment. which once i added about a 1/4 inch of cardboard, it works like a champ now. i get about 2.4 hours of cleaning before it returns home to charge again. This is a good buy but do not forget to add some type of shim inside the battery compartment.
