How long will it last? There are many variables that affect how long it will last. A few of them are: elevation, room temperature, inconsistent breathing, CPAP device pressure settings, how many times you got up that night, How many times you stopped breathing that night, and the different power levels required of various PAP devices. The battery runtimes will be different for each person. Using a low-med setting helps the battery last much longer.
