• I don't have a run-time calculator but: It's a really long time... A= W/V .4mw/120V = .000000333333333 A Watts = .4 Volts = 120 AMPS = .000000333333333 What only draws .4 mw that you want to protect on UPS? Just curious... hope this helps a bit, sorry, I don't have formula for runtime extraction.

• This unit is designed to support much more than 4 mA use, so it really should last a long while.
