Airline policies  regulations are constantly changing. Current regulations do allow CPAP/BiPAP Machines and Lithium Ion Batteries (like the one in this battery pack) to be carried onboard commercial flights; however it is always important to check with your airline prior to travel to determine exactly what requirements they have for carrying medical equipment on board. Many will require a letter of medical necessity from your doctor or a copy of your prescription.

      • Using a heated humidifier with your battery pack is not possible. Please disconnect the H5i Humidifier from your S9™ whilst using the CPAP battery
      • Always use the power supply provided to recharge your battery pack. Using a non-approved recharger may damage your battery.
      • Always use the proper DC cord for your CPAP/BiPAP machine. Consult your CPAP/BiPAP machine manual for specifications.
      • The C-100 can only be charged via DC using our DC Charger Cable which can be purchased from CPAP Batteries.

Q: Can the battery be charged from a ciagrette 12V socket like those in a car or caravan?

A: Yes, however you will need to purchase a DC charger which is not included in the package. The DC charger is an optional accessory and is $59. The package comes with included AC/DC charger only.

Q: Can i take the battery on an airplane?

A: Yes, the C-100 is 100 watt hours and is perfect for use on airplanes due to its small portable size.

Q:  Do i need to purchase any additional cables to run my CPAP?

A: No. The package comes complete with a DC Cable to connect your CPAP Machine to the battery and also the AC/DC Charger to charge the battery from the wall. If you wish to charge your battery via a 12V DC socket you will need to purchase an additional DC Charger from our store.

Q: How long will the battery run my CPAP for?

A: The exact time will vary from one customer to another. The lower the CPAP pressure requirements the longer the CPAP battery will last on a single charge. You can be guaranteed to get over 8 hours from a single charge however some customers get up to 11-12 hours.

Q: Can i use my humidifier?

A: No, the humidifier draws to much power and it will deplete the battery charge very quickly.

Q: How long is the warranty?

A: The warranty is 1 year. 

Q: How long does it take to be delivered?

A: Postage is normally between 3-5 business days. We use Australia Post EXPRESS parcels and we will provide you with a tracking number. If you require a battery urgently it is best to let us know so we can put a priority on your battery and get it out as fast as possible.

Q: Why should i buy the C-100 over the ResMed RPS2?

A: There are many reasons. The first is cost! Our batteries retail at around $200 less than the RPS2. The C-100 is also more powerful, smaller and can be chared and discharged simultaneously.

  1. Small and light yet powerful review by Gary on 4/7/2016

    I'm amazed at how such a small and portable battery can run my Resimed for over 10 hours! It has also saved me a few times of late with blackouts etc. Well worth the price.

  2. Good Quality. Small and light review by BOBBY on 10/21/2015

    The great thing about this battery is that it fits in the bag with your CPAP. It has also been a life saver when we have had a few blackouts. The battery is very sleek and comes in a nice bag with everything included. Thanks to Nick who explained everything to me as i was a bit lost!
