    Important Tips

    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: The length of run time of the battery is dependent on environmental factors such as temperature and altitude, as well as the user of the CPAP machine. The pressure setting will effect the run time as will the leak rate. A very high leak rate will cause the machine to shut down and a low leak rate will cause the machine to work harder to compensate for the leak thereby reducing the run time. Check the compliance report for incidents of apneas as an indicator of leaks.
