    User Manual: To view the Respironics Battery Pack manual, click HERE. This document holds a print date of 08/28/2009. It may provide information meant for older machines, please read through this important tips tab for current warnings and specifications.

    Instructions for Charging the Respironics Battery Pack:

    1. Remove the charger from the front zippered pouch of the carry case.
    2. Plug the 12V power adapter (cigarette lighter adapter) of the charger into the 12V DC power port attached the battery pack.
    3. Plug the power cord into the adapter.
    4. Plug the power cord of the adapter into a wall outlet.
    5. WATCH the light on the charger when it is plugged into the wall outlet to ensure it turns RED, even if it is RED only briefly. The RED light indicates the charger is correctly connected to the battery. The light may be RED for only a short time before it changes to orange.
    6. ORANGE: During the normal charge operation, the LED light turns ORANGE when the battery charge is 80-95% charged.
    7. GREEN: The LED light turns GREEN when the battery is fully charged.
    8. Disconnect the battery from the wall outlet and charger when the LED light turns Green.
    9. Store the charger and cord in the front zippered pouch.
    10. It is recommended to maintain a minimum charge 20% to 25%. Fully charge the battery prior to storage.
    11. Partially charging the battery occasionally will not cause harm to this lead acid battery.

    Replaceable AC Charger

    If the AC charger should be lost or fail, a new one can be purchased. Visit the Battery Charger for Respironics Battery Pack page to view and order this item.

    400 Watt Minimum DC to AC Inverters: The Respironics battery must be charged from an AC source. Charging the battery pack from a direct DC source is NOT recommended. An inverter converts DC power to AC power. The AC power can be used to charge the Respironics Battery Pack. The inverter must be a minimum of 400 Watt. Consider the 400 Watt DC to AC Power Inverter.

    Air Travel: The Respironics Battery Pack uses a sealed, lead-acid battery, which are allowed as carry-on luggage by the FAA and TSA. In-flight use will be determined by the airline and should be contacted on an airline-by-airline basis.

    Preparing For Travel: We suggest purchasing the battery pack far enough in advance so the battery can be tested with the your CPAP machine. This allows you to determine the actual run time using the machine at your pressure setting. Additionally you can test whether or not heated humidification is required for your comfort.

    Regarding Heated Humidifiers:

    For optimum performance of the battery pack, plan to use the CPAP without a heated humidifier. Alternately, connect the humidifier but do not turn on the power. Add water to the chamber as usual and the humidifier will act as a passover, non-heated humidifier.

    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.

    Please note that some heated humidifiers are not capable of being operated on 12volt battery power sources. PR System One and PR System One 60 Series heated humidifiers will heat and will draw significant battery power. The M Series heated humidifiers with the 6'' 'pigtail' connectors are capable of running on 12volt DC power sources. Earlier model M Series heated humidifiers without the pigtail are not 12Volt capable, nor are the Legacy model REMstar and stand-alone H2 humidifiers. The older non-DC capable humidifiers will act as cool passover humidifiers and will not heat.


    • DO NOT store the battery in a very hot environment such as a vehicle in hot weather, in direct sunlight or near a heat source such as camp fire or stove. The battery may corrode, ignite or create an electrical shock hazard. The optimal storage temperature is 77°F.
    • The battery MUST be in an upright position during charging and use.
    • Remove the charger from the carrying case BEFORE charging the battery.
    • DO NOT drop the battery or strike with heavy objects. Damage or deterioration may result from dropping or striking.
    • If the battery leaks and the gel spills on the skin or clothing, IMMEDIATELY wash it off with plenty of water. If the gel comes in contact with your eyes, immediately flush your eyes with plenty of clean water and seek medical attention.
    • Use the battery in a well ventilated area.
    • Replace the battery if it fails to charge or you notice a decrease in capacity.
    • Inspect the power cord for signs of damage. Discontinue use and replace the charger (enclosure of cord) if it is damaged.
    • Do not underestimate the weight of the battery.
    • Battery Fuse: To ensure proper operation of your battery, use a 15A fuse only.
    • Some older heated humidifiers will not heat when using DC power. They will instead act as a cool passover humidifier.

    CPAP Video & FAQ

    Frequently Asked Questions (FAQs)

    What type of power does my CPAP need?
    Most CPAP, APAP and BiLevel machines today are designed to operate on both AC and DC voltage. In the United States, the AC current from a wall outlet is 110 volts. Overseas, the AC current is usually 220 or 240 volt. Most batteries produce 12 volt DC current.

    We include information about the power needs and capacities on the pages our products. Please see the "POWER" tab on any machine product page for this information. You can also see a summary of the voltage range and whether it is DC capable on our Compare Charts.

    Here is a video explaining differences in power cords and power supplies of various CPAP machines:

    Will my CPAP operate on DC / battery power?
    All CPAPs will operate on DC power with the use of an Inverter to change the current from DC to AC before it reaches the machine. However, many will operate on DC power without the need for an inverter, just a power cord that plugs into the CPAP and ends in a cigarette lighter plug.

    Inverters do require a lot of power. If you need to use an inverter to run your machine on battery power, the inverter will probably take about half the life off the battery.

    To determine if your CPAP will operate without an inverter, look for a DC outlet on the machine, either at the back or on the side, with a single opening directly in the center. It should be labeled "DC POWER" or similar term. You can also review our Compare Charts to see if your machine has a optional DC cable option.

    Here is a video describing different DC cable and battery options for various machines:

    Will my CPAP operate overseas?
    An adapter may be required to plug a US power cord into a wall outlet in a foreign country. sells an assortment pack of World Traveler Power Adapter Plugs, which allow CPAP machines to plug into different types of wall sockets found in different countries.
    All the models sell contain power converters that enable the machine to operate on any AC current from 100 to 240 volts without any adjustment.
    How do I use a battery to operate my CPAP?

    All machines can connect to DC power. Some machines are configured to operate on DC Power and have a DC power outlet. Other machines require AC power and will need an Inverter that turns DC power to AC power.

    Having the proper equipment is the biggest key to successfully operating the machine from a battery. For example, if your machine does have a DC outlet and you want to run your machine from a marine battery, be sure to get the correct DC cable for the machine, as well as an adapter cable with alligator clips that fits over the cigarette lighter plug. sells complete battery kits with everything you need for many machines including the correct cables for those machines and batteries. If you have questions about the specific power needs of your machine, review the 'Power' tab found on the machine's product page, or give us a call at 1-800-356-5221.

    What type of battery should I use?
    For longer battery use, we suggest using a deep-cycle marine battery to power the machine. A deep-cycle marine battery is heavier than the ordinary battery, but it has many advantages. The battery is easily found at auto shops and it provides power to the machine for an extended period of time. For example, a CPAP machine set at 10 cm H20 and charged on a deep-cycle marine battery will usually last three nights before it needs to be recharged.

    There are small, portable battery packs that will operate a CPAP set at 10cm for at least one night, or about eight hours. sells full Battery Kits that come with everything needed to run your machine off battery power including the correct cables needed for your machine and a battery. You can find the battery kit for your machine Here. On each battery kit page, you can input your machine and pressure setting to see an estimate battery life for your machine.

    Some machines have batteries created to be used specifically with them only. Here are some of the machines we carry with integrated or specialized battery options:

    Transcend EZEX miniCPAP™ Machine
    Z1 Travel CPAP Machine
    Transcend Auto miniCPAP™ Machine with EZEX
    Z1 Auto Travel CPAP Machine
    How do I prepare for power outages with CPAP?
    There are a lot of back up battery choices out there that can give you peace of mind in case of a power outage. The Transcend Travel CPAP Machine has Battery Options available that can set up as a fail-over, back up battery. Review the 'POWER' Tab on the machine page. sells Battery Packs to accompany your machine if an integrated battery is not available.
