Query: Runs a bit warm

This replaced a ADP UPS which had given up after many years. It seems to do the right thing in that it supplies power without interruption when there is a power glitch. The only thing I am surprised at is how warm it runs. This implies a constant power drain. It seems this is well in excess of the power needed just to keep the batteries charged.We are not using the automatic shutdown feature so no comment can be made about that function.
