This battery is ideal for travel, but it also provides back-up power in case of an unexpected mains power failure. 

A long lasting lithium-ion battery powers this device. It can be used with the S9 and S10 series CPAP machines.

Battery running time estimates are hard to provide as consumption is dependent on device model, settings, leaks, battery quality and age, unique breathing patterns of the patient, environmental conditions and external accessories such as a humidifier and heated tubing. 

A good estimate of battery life would be to set the CPAP device to running at 10cm pressure without humidifier or heated tubing. In this case, the battery will have an approximate charge good for 11 hours working time. If extra load is place (for example, 20 cm H2O, with medium heated humidifier and heated tubing settings) the battery life estimate is only 2 hours. If you will be highly dependent on the battery, we recommend that your purchase additional batteries for convenience and peace of mind. 

The battery charge display indicates the charge level and has a visual and audio alert for when the charge is low.

Another feature is the Battery Coupler (sold separetly) which connects two RPS II batteries in a series.  It will automatically switch to the other battery when required. 

Please Note: If you are using an S9 series CPAP device you will also need a DC cable, and if you are going to use this battery with an AirSense 10 model, you will also need to order the AirSense10 battery adapter and the AirSense10 DC cable.
