The Extended Life Battery has twice 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.
This product works with both the Z1 and Z2 portable travel CPAPs.
* Results were obtained via bench testing under simulated operating conditions. Actual run time may vary due to machine settings, machine pressure, and personal breathing. Lower pressures will result in longer battery operating times.
Warranty is one year.
