Default Engine run time to keep battery charged

If you turn over an engine periodically to keep it charged, how long do
you run it to make up for the charge lost in starting?

In this case it's my neighbor's 87 Buick Regal while he's in the
hospital.

A real test at idle, turn on lights. If revving the engine makes them
brighter, you have little reserve power to charge battery. For a fast
charge you need 14 or more volts.
