The NEW Extended Life Battery has double the battery capacity of the original Overnight Battery, so even at the highest settings (20 cmH2O, Z-Breathe 3) cpap therapy should last 8.9 hours.* With lower pressure settings you should get even longer therapy.
* Results were obtained via bench testing under simulated operating conditions. Actual run time may change due to machine settings, machine pressure, and personal breathing. Lower pressures will result in longer battery operating times.
Plan on traveling? The power supply auto adjusts from 100 to 240 volts. All you need to add is the proper plug adapter for the country you are visiting.
