    Product Specifications

    Extended Life Battery with Shuttle Weight: 1.14 lbs

    Extended Life Battery with Shuttle Dimensions: 6 in. x 3.5 in. x .75 in.

    Estimated Runtime:Manufacturer testing shows that the Extended Life Battery will power a Z1 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.

    FAA Approved? Yes.

    Important Tips

    Charging The Battery

    1. With both the Z1 or Z2 and the battery fully inserted into the PowerShell, plug the power supply (AC to DC Adapter) into the wall outlet. The Z1 must be in standby mode (display reads 0.0) to charge the battery.
    2. The battery status indicator on the Z1 or Z2 will flash when the battery is charging. The number of solid bars indicates the current level of charge. The battery charging is complete when the 4th bar stops flashing.

    FAA Compliant

    Per the FAA, this product meets the requirements set by the FAA for air travel.

    FAA Regulations for Batteries

    PLEASE NOTE: If the PowerShell does not appear to be charging, disconnect the Z1 or Z2, battery, and power supply and reassemble. Make sure you hear the components click together and see that the DC plug (silver cylinder in the bottom of the PowerShell) goes into the hole in the CPAP and then reattempt to charge the PowerShell.
