Important Notes
5
Use as a Power Backup
The Battery Pack is equipped with a standard smart charger keeping the
battery topped off and ready to go as an emergency power backup during
power outages.
You may keep the Battery Pack plugged into a wall outlet and your
CPAP/BiLevel machine and in the event of a power outage the Battery
Pack will automatically begin powering your device.
Battery Pack Run Times
Multiple factors will affect usage times including, but not limited to,
device type, whether a power inverter or converter is used in conjunction
with the battery, pressure setting, and altitude. The use of heated
humidification or tubing will significantly reduce expected run times.
Older model CPAP and BiLevel machines, which were designed to operate
on a higher voltage, will produce lower average run times than newer
models which are designed to operate at lower voltages.
Average run times are based on Respironics System One and ResMed S-9
devices with no heated humidification or tubing.
