The Extended Life Battery from HDM is a rechargeable battery that integrates with the Z1 and Z2 PowerShell to be the smallest integrated CPAP battery option on the market. The Extended Life Battery has twice the capacity of the original battery. With twice the capacity of the original battery, the Extended Life Battery gives you more cpap therapy even when you can’t plug in your Z1 / Z2. Take it on the plane for overseas travel, in your backpack for overnight camping or in your saddle bag for motorcycle road trips.
Estimated run time: Manufacturer testing shows that the Extended Life Battery will power a Z1/Z2 CPAP at the highest settings (20 cmH2O, Z-Breathe 3) for 8.9 hours. These results were obtained via bench testing under simulated operating conditions. Lower pressures will result in longer battery operating time. Actual run time may vary due to machine settings, machine pressure, and personal breathing.
Shelf life: Batteries are shipped with between 30% and 50% of rated capacity, providing a minimum of 6 months shelf life when stored at 25°C. If storage temperature exceeds 25°C over a 6-month period then shelf life will be reduced and the battery should be recharged periodically
