I often wonder why people don't call the manufacturer first. Is it that
difficult?

I would contact iRobot and ask them what the recommended procedure is.

Thanks for that everyone: I will try it.

Obviously no one calls iRobot for this question. they just want to
sell their expensive batteries. The last thing hhey want is to advise
on how to take the battery compartment apart. They even go to the
length of putting special screws on it to prevent anyone taking it
apart (using a triangular headed screwdriver: Has ANYONE ever come
across that on any other unit of any type whatsoever?)
