Kitchen and Housewares Reviews of Generic iRobot Roomba Replacement Internal Battery Pack for Battery 4905. Fits Discovery, Sage, Red, and Dirt Dog Models
Customer Review: Definitely works
Summary: 4 Stars
I have to spend another $28 to get solder iron, solder and solder vaccum, so after all I didn't save much money, but it definitely works.
It is a little hard to open because after removing all the screws, the top is actually glued on. I tried to remove cover by force but nearly broke it. Once the top is removed, the rest is easy, just match the colors and solder the wires to the metal plate. Then put the cover back and that's it.
Customer Review: Does require a bit of skill
Summary: 4 Stars
As others have mentioned, the battery case is hermetically sealed. A couple of regular screwdrivers will get it open with a few minutes of careful prying. The replacement pack comes with short leads. It's probably easier to connect the old leads to the new ones and use the heat shrink tubing on the connections. I chose to desolder the old contacts and solder the new leads to the contacts. It's tight working quarters in there and in hindsight wished I had just spliced the wires together.
I give it 4 stars, not for the effort level, but for the lack of documentation.
Customer Review: Good replacement - skill needed to install
Summary: 5 Stars
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.
Customer Review: Helped me save some money!
Summary: 5 Stars
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.Customer Review: I am terrible at soldering and I did it!
Summary: 5 Stars
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!
