My Roomba i7 is 5 years old and was still on the original battery. The scheduled cleaning was taking around 4 hours and 20 minutes to complete with 2:20 being cleaning and 2:10 for recharge and the battery would be nearly drained at the time it docked the second time. This battery is almost 2x the original's size so I had hopes that it might do the whole job without docking between. While it did not achieve that, it did charge almost an hour faster than the old battery did and reduced the overall time by just over an hour. The installation was a piece of cake - pop 6 screws out, slide out, slide in and put the screws back in. Good opp to clean those brushes too while in there. It would have been nice to have instructions on the replacement but easy to find a youtube video. Absolutely loving that the whole cycle time is shorter!

Installation was easy and I was able to swap this battery in my Roomba I2 in about 5 minutes. Removing the bottom plate also gave me an opportunity to clean the area underneath that does not get touched very often! In my pictures I use a screwdriver to point to the tab that needs to be pulled away from the battery to release it. The new battery was a perfect fit and added about 40 minutes to my run time when compared to my 5 year old battery. At one third the cost of the original Roomba battery it is an excellent choice.

Unfortunately seems to be an issue with the charging circuit in my i4+ EVO 'bot, so I can't say much of durability or length of charge. It did obviously have a charge when it arrived. If my 'bot comes to life, I will further amend this review.

I got this replacement battery for my Roomba i2, and it works perfectly! It lasts way longer than the original battery, so I can clean more of my house in one go. Installation was super easy, and I feel better knowing it has safety features. Highly recommend if you need a new battery for your Roomba!

My i7 was running on the original battery and was starting to have problems making it back to the dock. I replaced the old battery with this one and now it is running like new. The battery was very easy to install and dropped right in. I will update this review if there are issues in the future.

Replaced my original 5 year old battery in my iRobot j7+ vacuum with this model. The original battery used to last around 3 hours before needing charged. I have a large house so this was enough to do the main areas but if I cleaned the whole house it would need to charge in the middle. The old baterry got to the point it would last about 20 minutes. New battery fit perfectly but only lasts about 35 minutes before needing charged. It has almost twice the amp hours of the original (supposedly), so should last much longer. Not much of an upgrade over the old worn out battery.

We have a Roomba i3 that was really starting to underperform. I wasn't sure if the battery was getting old or if the computer was starting to malfunction. It would vacuum for a short while, in slightly apathetic manner and then return to its dock. The new battery not only gets this Roomba to last longer, it also has a renewed vitality! It's performing like a new irobot! If you have a sluggish Roomba that is a couple years old - new batter (as well as a good cleaning and new brushes etc) really breath life back into it.

The battery on my i3 has been getting worse and worse, and the brand name replacement cost is so high you might as well buy a new vacuum. When I found the TenHutt replacement I was excited, but skeptical, about how much of a charge it would hold. It was easy to swap out the old one and install the new one, it took a couple of minutes for my vacuum to reconnect, and voila, it worked wonderfully!!! The battery charge lasts long enough to do my main floor in one charge, and it feels like my roomba isn't chugging along anymore, but like it's a brand new unit. I'm super happy with my purchase and hope it lasts as long as the oem.
