Power Consumption - Cobra CPI 150 Operating Instructions Manual

For each piece of equipment
you will be powering with
your CPI 150, you must
determine the battery's
capacity (how long the
battery can deliver a specific
amount of current). For
example, automotive
batteries usually provide
25 amperes of current. A
battery with a reserve
capacity of 180 minutes
can deliver 25 amperes for
180 minutes before it is
completely discharged.

POWER CONSUMPTION

Calculate the total watt-hours
of energy consumption
(power X operating time),
then divide the watt-hours
by 10 to determine how may
12 volt ampere hours will be
consumed.
