The entire Instructions for the CPAP.com Battery Pack can be viewed:
HERE. Do read all instructions carefully prior to using the battery pack.
Word of Caution to RESmed S8 and S8 II Machine Users YOU MUST USE the
DC-12 Converter For S8 Machines when drawing power directly from a DC battery source (no inverter and no humidifier). Failure to do so can result in damage to your CPAP. ResMed S8 machines with a Humidaire heated humidifier (h3i and H4i) require a pure AC power source in order for the humidifier to work properly. The machine disables the humidifier when connected through DC Power. The machine and humidifier will both work properly only when connected to pure A/C power. You will need the
DC to AC Pure Sine Wave Power Inverter to operate both.
ResMed VPAP Auto 25 and VPAP ST The ResMed VPAP Auto 25 and VPAP ST use a different cord,
DC-24 Converter For ResMed. Refer to the
Respironics Battery Kit for ResMed VPAP Auto 25, VPAP Malibu & VPAP ST Machines for a battery kit for these machines.
DC to AC Pure Sine Wave Power Inverter for Resmed S8 Machines ResMed S8 machines are required to use a pure sine wave AC power source when connecting through an inverter; particularly, the ResMed S8 Compact is not DC compatible and must plug into a wall socket. The
DC to AC Pure Sine Wave Power Inverter provides clean AC power to any CPAP. You will need this product to operate the S8 Compact or any other S8 machine using the standard AC plug.
Charging Instructions: Use ONLY the included Charger to charge the CPAP.com Battery Pack - Plug the AC outlet adapter of the charger into a standard 110 volt household electrical outlet. If charging outside the United States using 240V current, an appropriate outlet adapter will be required. The battery cannot be charged from a solar or battery source unless an inverter is used to change DC to AC power.
- Plug the 12V power adapter (cigarette lighter adapter) of the charger into the 12V DC power port of the battery pack.
- Both lights on the charger turn red once connected to the wall outlet and battery. The light on the AC outlet adapter shows red when the battery is charging and turns green when the battery is fully charged. The light on the 12V power is always red and indicates the charger is plugged into a wall outlet.
- When the light on the AC outlet adapter turns green the battery pack is fully charged. The light on the 12V power adapter will continue to be red.
- Charge time takes up to 10 hours when starting with a fully discharged battery. Do not leave the battery connected to the charger for more than 12 hours.
- When the battery pack is fully charged, disconnect the battery pack from the charger and disconnect the AC outlet adapter from the wall outlet. Do not overcharge the battery. The light on the 12V power adapter will remain RED even when the battery is fully charged and the light on the AC outlet has turned GREEN.
- If not used, you can expect the battery to hold a charge for to 6 to 9 months. Recharge at that time.
REGARDING HEATED HUMIDIFIERS: 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. The later 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.
For optimum performance of your battery pack, plan to use your CPAP without the heated humidifier. You may also have the humidifier connected and filled with water, but without the power turned on. This changes a typical heated humidifier into a passive humidifier.
We suggest purchasing your battery pack far enough in advance so that the battery can be tested with the your CPAP machine. To determine the actual amount of power time you will receive and whether or not heated humidification is required for your comfort, test the battery at home before traveling.
