A fully charged Z1 and Z2 Extended Life Battery will last 8.9 hours at a treatment pressure of 20 cm H2O and Z-Breathe setting at 3. These results were obtained via bench testing under simulated operating conditions at the highest machine settings.  Many individuals are able to get two full nights use from one battery charge.


Actual run time may vary due to machine settings, machine pressure and personal breathing. Lower pressures will result in longer battery operating times.
