New Roomba batteries

For some reason I am the Roomba battery kiss of death. I’ve been through two batteries in about three years. Last time I just bought a new Roomba on special instead of replacing the battery. Its hard to justify three Roombas in the house though, so this time I’m trying something different — I’ve bought replacement cells for the batteries from ebay, and will install them in the yellow shell myself. This sounds like its pretty easy to do, and there are several supplies who sell these cells.

I’ll let you know how I go.
