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. Take it on the plane for overseas travel, in your backpack for overnight camping or in your saddle bag for motorcycle road trips.

The Extended Life Battery is a rechargeable, lithium-ion battery that integrates with the Z1 PowerShell to be the only fully integrated CPAP battery option in the US market.
