Twice the Capacity of the Original Battery
The Extended Life Battery is a rechargeable, lithium ion battery that integrates with the PowerShell to be the only fully integrated CPAP battery option in the US market.
With twice the capacity of the original battery, the Extended Life Battery give you more CPAP therapy for 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.
If you already own a PowerShell, HDM will upgrade the firmware in order to charge this new battery.
