ya, unplug the sump pump, fill the sump with water and see if the battery
powered pump works. OR take the battery to your local auto shop and have it
load tested.

The calendar says it has been three years since I had the back-up
pump installed and thus, according to the instruction manual the battery
should be replaced. Is this automatic or can I do some test to see if
really needed.
