CPAP.com Battery Kit for S8 Machines

Small & Lightweight. The 1.25 lb CPAP.com Battery Pack is surprisingly small and lightweight. Add the carry bag and battery charger and it is still only 2.02 pounds. It features robust power that is rarely seen in battery packs twice its size and weight. The battery kit plus the included DC-12 Converter For S8™ Machines is just 3.5 pounds.

Lithium Ion Battery. This battery does not have typical "Battery Effect" issues, where you must discharge the battery before you can recharge. The lithium ion battery can be recharged at any discharge level without losing charge time due to battery memory loss. Using sophisticated circuitry, the battery pack is specially designed to limit the unit from under charging and over charging. The CPAP.com battery pack will take approximately 10 hours to fully charge.

Approved for Travel. This battery has been approved by the United Nations and Department of Transportation as tested safe for travel.

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. This battery kit comes with the CPAP.com battery and the DC12 Converter for S8 Machines. If you have any questions call our toll free number 800-356-5221 for assistance from a CPAP expert. The following machines are compatible for this kit:

• S8 AutoSet II CPAP Machine
• S8 Elite CPAP Machine
• S8 Elite II CPAP Machine
• S8 Escape Travel CPAP Machine
• S8 Escape II CPAP Machine
• S8 Vantage EPR Auto CPAP Machine
• S8 VPAP Auto BiLevel Machine

Word of Caution to RESmed S8 and S8 II Machine Users

YOU MUST USE THE DC12 Converter for S8 Machines in conjunction with any battery source, when using an S8 or S8 II machine. Failure to do so can result in damage to your CPAP.

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.

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

1. 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.
2. Plug the 12V power adapter (cigarette lighter adapter) of the charger into the 12V DC power port of the battery pack.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
