Multi-colored charging status lights. Charge Time.
The charge time is 10 hours on a completely drained battery. Less if there is a still power in the battery when charging begins. Shelf Life.
This battery can sit 6 - 9 months when not in use before needing to be recharged. Estimated Run Times.
Please see the "Machine Pressure and Battery Performance" feature below to estimate the battery run time for your machine at your pressure setting. Using a heated humidifier on a 12volt battery power source will significantly reduce the amount of power provided. In most cases, usage is reduced to less than half the estimated operational time. CPAPs or BiPAPs requiring inverters reduce the power time even more. Compatible Machines.
