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.
