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: A1 if you can do it
Summary: 5 Stars
There is nothing wrong with the battery pack. I've yet to see how much better they are then original as I just got it working. One just needs to know that getting the lid off that battery case is a bit of a battle it is screwed and glued. Pry it firmly. You will also need to solder and shrink tube the connections. Worth the effort for the money saved I think.Customer Review: The battery works great, however...
Summary: 5 Stars
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.Customer Review: Tenergy NiCD Battery Pack for iRobot Roomba
Summary: 4 Stars
I ordered three of these batteries and they were shipped very quickly. Each came with a triangular screw-driver necessary to open the Roomba battery pack housing. A minor amount of soldering was required and now my Roombas are working like new. So far so good, but the true test will be how long these batteries last. The literature says 1000 charges.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!Customer Review: Not bad, but some documentation would have helped.
Summary: 3 Stars
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.
