Can I use my car battery to power my machine?

This is not recommended. Find out why.

This is not recommended because car batteries are not designed to be discharged by more than 30%, and their operational life may be significantly reduced. Instead, consider obtaining a deep cycle battery or a marine battery if you are travelling in an area where there is no mains power. A deep cycle battery can discharge by as much as 80%, and a marine battery can discharge as much as 60%.

A car battery can be used in an emergency, preferably without a humidifier. Using a humidifier will drain the battery to a point where it may be unable to start the car.
