Terrific battery to replace your Roomba battery
Roomba battery buyer (Chicago, IL) 7/14/2013 3:42 PM
This battery was easy to pop into the roomba 450 model. I charged it overnight and used it the first time today. The roomba ran for an hour and a half! I never got more than 75 minutes from the original battery. I had hoped that iRobot would come out with a new & improved battery, but after waiting over 2 years I now realize they are not developing new batteries for this series. Based on other people's positive experiences and my own I would recommend this battery as a reasonably priced and better (or on par) performing battery than the Roomba brand battery.
Excellent battery

I bought this battery with a little skepticism because of all the bad pub that non-OEM replacement batteries get. However, all the positive reviews convinced me to give it a shot, and $32 is a great price. I've used the battery for a couple of months now, and I can honestly say that it outperforms the original battery in my Roomba 400 series robot. It runs for close to an hour. I can strongly recommend this battery.
King of my Roomba fleet ;)

Got this and my 500 series battery. Both are working well for the first 2 weeks (how long I've had them). Energy storage seems to be sufficient to allow each Roomba to do two rooms. This is equal or better than the original battery. So far I'm happy with this purchase. The problem as I see it is Roomba needs to redesign their Roomba battery maintenance subsystem. It currently overcharges the battery which is why the battery only lasts 1 year or 300+ charge cycles instead of 1000-1500 charge cycles or 3-5 years for a battery that's properly maintained. Still $30/year/Roomba is a livable price to keep these units running/usable. And this behavior keeps All-Battery in business shipping replacements for burnt up batteries.

The shipping took over a week, and I was un-happy about that, but the battery performs very well. It seems to last longer than the original. I am happy with the purchase, but the shipping was slow.
Better than factory battery

I originally purchased the do it yourself kit. These packs run longer and charge faster than the factory units and are much cheaper. They are still only good for about a years worth of regular use, but that's still a good value.
better than the orignal

I purchased this battery to replace the orignal roomba battery. I am very happy with its performance, seems to last longer then the orignal did out of the box. The Roomba now does 2-3 mid size rooms before returning to home base for a charge.
Happy Home Owner

My daughter purchased this battery from you some time ago and is absolutely tickled with its performance and your service...so I am buying new battries for my wife for her Roomba for Mother's Day. She says the origingal battery ever performed anywhere as well and as long as her new one does. I'll be back for sure...you are now in my "Favorites"
