Extended Life Battery


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 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.

If you do not own a PowerShell, you can purchase one here and it will ship with a new Extended Life Battery and will not need an upgrade.

The Powershell’s Extend Life  Battery is covered by a 6 month warranty.
