    CPAP Battery

    Power Solutions

    Battery backups in CPAP therapy are used to travel or to run your machine in case of power outages. There are two main options for batteries: integrated battery backs and stand alone batteries. Integrated battery packs attached to your machine, power it for more than 8 hours and travel very well. Stand alone battery packs vary in size depending on the life of the battery. Many are travel friendly. Some machines require unique or custom power configurations. Check with us first!

      How do I use a battery to operate my CPAP?

      How do I prepare for power outages with CPAP?



      How do I dispose of an old or damaged battery?

    Lithium-ion (Li-Ion) and small sealed lead-acid (SSLA/Pb) batteries should be recycled and/or disposed of in accordance with local regulations. These batteries should not enter the solid waste system since they may have a negative impact on the environment and waste management process.

    Please contact organizations committed to responsible recycling of batteries. Lead-acid batteries may also be taken to a location where automotive starter batteries are accepted.

    Lead-acid batteries include:

    • Respironics Lead Acid Battery

    Lithium-ion batteries include:

    • ResMed Power Station II Battery
    • Transcend Multi-Night Battery
    • Z1 Battery
    • C-100

      How Can I Power a CPAP While Camping?

    Powering a CPAP while camping or off the grid can be done by using a battery specifically designed for CPAP machines, or by using a deep cycle car or marine battery and necessary cables and converters. Let's go over these two options in greater detail:

    Option 1: CPAP Batteries

    There has been a big increase in interest over the years for having a special battery designed to handle the power needs of a CPAP machine. Manufacturers have responded, by creating some great products designed to power a CPAP machine, even off-the-grid. Lithium-ion batteries get their charge from a power outlet; and when fully charged, can power a CPAP machine for a modest amount of time, perhaps even as long as 2 nights. How long a battery lasts depends on the type of machine, if humidification is used, altitude, and pressure setting. It's also important to note that using an AC power inverter will greatly reduce battery run times as well.

    Higher elevations will result in the machine needing to work harder to get to therapeutic pressure, and as a result the battery drains faster. Humidification is not recommended for campers, as humidification creates a substantial drain on the battery, and can greatly reduce battery run times.

    Option 2: Deep Cycle Car and Marine Batteries

    What's a deep cycle battery? A deep cycle battery can be purchased from an auto parts store, and is the same kind of battery found in a car. A deep cycle battery uses a chemical reaction to generate electricity, and are heavy and bulky; but they have the advantage of being able to deliver a charge for longer than a Lithium-ion battery. In order to connect a CPAP machine to a deep cycle battery, one should look into using a AC power inverter or a DC cable with a cigarette lighter attachment (if a cigarette lighter plug is built into the battery). Keep in mind, an AC power inverter is going to consume a lot of power while powering the machine and the use of an AC power inverter will greatly impact battery run times.

    Option 3: Pick a Campsite with Electricity

    Many campsites around the country offer electricity as an option for campers. In most cases, a person can set up a tent and find a plug nearby and power the CPAP machine with an extension cord. For most campers, this is the easiest and cheapest option to power a CPAP machine during a camping trip.

    Not all batteries will work with all machines. Each machine has different power needs, which is why it's important to verify compatibility with a particular brand of battery before purchasing. Some machines require using an inverter (a device used to convert DC power to AC current); some batteries have the correct connector to hook into a specific machine; with others, the right connector is sold separately. It just depends on the machine and the battery.

    Did You Know?, Power Solutions

    • Portable CPAP batteries can power a machine for about eight hours before it must be recharged.
    • If your machine does not have the ability to directly hook up to a battery or dc power source, you can use an inverter or converter depending on your machine.
    • A typical rechargeable CPAP battery can power a CPAP machine for eight hours on average.
    • If your battery isn't holding the charge it should, it may be time to change the cell.
