I ordered this replacement battery since I can solder some wires and am mechanically inclined to some degree. The iRobot people wanted too much money for their replacement to fit my old Roomba; this battery met my needs. Like I said, if you enjoy tearing your old Roomba down to tune it up etc, you'll prolly be fine twisting 3 wires together and soldering them. The company who shipped my battery forgot to ship along the funky triangle tip shaped screwdriver. They did mail one out a week or so later, which was nice of them! I got excited though, and couldn't wait for the special screwdriver, so I simply drilled out the old screws that hold the battery case together and just used black electrical tape to hold it together and that worked great! The new battery is holding up well and charges up fast! I'm happy I ordered this replacement.

Got this item from amazon. The seller upgraded the order to 3400mAH for free. Like the others mentioned, you have to be carefull opening the battery as it is glued. Once it is opened then it is simple procedure of soldering the 3 connection. Write down how the layout is or better take a close up picture. SO you don't connect the black wire where the red one is supposed to go.

After the first charge (about 3-4 hours), the roomba just kept going and going for a long time. I wanted to discharge it totally before recharging it.

Great deal for 29.95

I got this battery pack after my second Roomba battery started running short. I was pleasantly surprised to receive a free upgrade to the 3800 mAh pack instead of the 2400 mAh I ordered. A bonus in the package was the special triangular screwdriver to get the battery case apart. The order was received one week after ordering, another plus.

Installation was a little tricky, some fiddling with a pair of flat-tip screwdrivers to get the case apart. You'll need a soldering iron to re-attach the connections and a bit of patience to get the case back together, but it sure beats $70 for an out-of-stock battery from IRobot. There are some rough instructions on www.all-battery.com website.

Excellent replacement item. Super easy to solder and get the Roomba back up and running. Got the 2400 mAh battery and lasted a good 1 hour and 20 min. Now that I know how easy it is, I will spend a little more for the 3600 mAh battery. I am so impressed with how easy it was. If you can solder poorly, you can do this!

Batteries were somewhat easy to replace once the plastic case opened. It seems that some of the cases are glued shut.

The replacement batteries do not have the same running time as the originals. On a full charge the Roomba runs for about 35 minutes. The unit periodically shuts down and then restarts, which was not normal with the original battery pack.

Not sure if this is due to the new batteries or another problem.

The replacement battery arrived fast, but the installation was harder than it needed to be due to a lack of documentation. i found some generic instructions online, but it would have been better to have some installation guidelines in the box. The battery was working well once it was installed and charged.

The product was as advertised and the addition of rubber jackets and the ends of the leads was a nice addition so that soldering wasn't necessary. The 2400mAh is only sufficient for about 1 hour's worth of operation compared to nearly 2 hours for the manufacturer's battery (which I'm guessing is 3000mAh although it's not advertised).

Although it's not the fault of this battery manufacturer, opening the Roomba battery pack can be very difficult. The plastic case is glued shut and requires extensive effort to open without damaging it. I used a Dremel to cut it open.

The cover of my original battery was superglued so it was very difficult to get it opened to replace the battery with the new one. I had to do some serious cosmetic damage (using chisel, hammer and hot metal) to be able to open it. Most likely it has void the warranty, he he. People should be aware of this difficulty before just buying a replacement.

works well

some skill to install

would buy again

good service from company and Amazon

The battery pack came in fast and it works great. It charges up in 2 to 3 hours. My original one needed 8+ hours to charge.
