We have a Roomba 500 series, purchased years ago. The battery finally gave up and wouldn't hold a charge anymore. Buying them from the manufacturer is very expensive so we looked for a more reasonable source. This battery came very quickly and has performed perfectly. It's been a while since we received it and it is still powering the Roomba for a full cleaning. It fits in the compartment just like the original battery, you won't go wrong with this unit.

Had this for a little over a week now and I was skeptical based on other reviews but it was hard to pass on the price. Charged the new battery overnight before I used it the first time and it ran for over an hour and a half before I stopped it. Have sinced used it 4 more times with the same results. It's been ages since we used our Roomba so I don't remember how long it used to last but I don't recall it being this long.

Every once in a while, the battery needs to be replaced and this works fine. Now my iRobot is fully charged and doing its job.

Battery life and longevity not the best

It is difficult to find a replacement battery for a Roomba vacuum cleaner. They can be found easily on Amazon at a reasonable price & quick shipping. You can also get a longer "life" battery, meaning less frequent recharging.

I thought my roomba was a goner but this battery brought it back to life. It has a pretty decent charge and battery life. Was an easy install after watching a short video.

Holds charge well and fits well. No issues. Seems like a cost effective replacement.

This battery only runs for maybe 20 minutes at a time before it has to charge for 4-6 hours. I have to charge it multiple times before it can finish cleaning a room. I've been pleased with the other aftermarket batteries I have purchased in the past, they all started out working well before their lifespan dwindled. This one has been terrible since the first day I installed it in my Roomba 650.

Muito bom

Lo use como sustituto para mi roomba

I am using it for iRobot Roomba 770. after one month, it is still working like new even though I am using it on a daily basis.

Compre una pila de mayor amperaje para mi roomba 980, fracaso total, supongo que la pila no se carga completo a pesar de que se indica llena. O se descarga más rápido, no lo se. En conclusión dura mucho menos tiempo que la original de Men amperes

Our little roomba had been in active for a few years due to difficulty in sending it in for servicing and spare parts. With this new battery, we were able to restore our roomba to new life and it is happily cleaning the house for one and a half hours on a single charge. Thank you very much!
