Somnetics Transcend P8 Multi-Night Battery System

This 8-cell Multi Night Battery for the Transcend II CPAP Machine can be worn on the arm with the included arm band or placed close by while sleeping. From the manufacturer's testing at a pressure of 14, when fully charged, the battery can run up to 14 to 16 hours. The actual battery life will depend on the users pressure setting, altitude, temperature and breathing habits.

Charging Voltages

Because the battery is charged using the Transcend machine's power supply, it can be charged from voltages between 100 and 240 volts.

Charge Using the Transcend Travel Machine's Power Supply

The battery can also be charged using the Transcend Travel machine's power supply. Simply plug the power supply into a wall outlet and into the Transcend CPAP battery.

Operating Temperature

The Transcend battery is for use in temperatures of 32 to 113ºF (0º to 45ºC). The Transcend battery is not waterproof and caution should be taken to keep it dry.

Battery Run Time

Environmental conditions and factors of your CPAP therapy can affect the run time of the battery including temperature and altitude, as well as pressure setting and leak rate. A leak rate that is very high causes the machine to stop running. The machine will work harder to compensate for a low leak rate which will reduce the actual battery performance.

Battery Storage

The Transcend Multi-Night CPAP Battery should be charged to a minimum of 40% before storage. The self-discharge rate of the battery will be much slower when stored in a temperature-controlled environment rather than a hot environment. Periodic recharging is recommended to maintain the life of the battery.

Colored Light Indicating Charge

When the battery is plugged in to receive a charge, the light will turn a bright orange color. This color will turn green after it is fully charged.

14 Hours of Portable Power for Uninterrupted Therapy

This device can generate approximately 14 hours of charging time when your Transcend device is on a pressure setting of 14. Certain factors like pressure setting, machine type, whether or not you're using the Transcend heated humidifier, altitude, and temperature can impact the longevity of the battery charge.

FAA-Approved for Use on Plane

Use your therapy while flying to your next vacation or business meeting since the Transcend Multi-Night Battery is FAA-compliant and approved for in-flight use.
