Overview of the Lithium-Ion Battery
The Lithium-Ion Battery for the ResMed Power Station (or RPS) II by ResMed is an expertly engineered, top notch device designed to supply power via the RPS II system. This battery is a standalone piece and functions great as a replacement or back-up item. The lithium-ion battery contains both visual and audible signals which alert users when the battery needs to be recharged; what's more, at under 2 pounds, the battery is very lightweight and exceptionally easy to transport and carry.
The lithium-ion battery can be connected with another battery for the purpose of providing double run time. In order to connect your battery with another battery unit in this manner you'll need to purchase a battery coupler. The battery coupler automatically switches to the second battery when the first is fully drained. Just by itself, this battery is capable of supplying power for at least 24 hours, which makes it ideal for travelers who are constantly on the move.
The lithium-ion battery for the ResMed Power Station II is not designed for any specific machine, but instead is intended to be paired with the RPS II and then used to supply power to corresponding CPAP and VPAP machines. The RPS II and battery coupler kit are sold separately.
