I would expect the battery current to be a lot closer to 10uA, but only with the power supply AC cord unplugged or hard-switched off if your power supply has a master switch on the back of it. With the computer running the battery current should be ~zero, and the battery lasts whatever its shelf life is, probably ten years.
