How to Choose the Best CPAP Battery for Your CPAP Setup

Planning ahead for your next adventure or preparing for a future power outage starts with a CPAP battery. CPAP batteries give you the ability to take your therapy on-the-go, in the wilderness, on a flight, or simply at home! However, the main reasoning behind having a CPAP battery on hand is you now have the flexibility to always bring your CPAP therapy with you whenever life takes you.

Whether you’re ready to roam the trails or want a CPAP battery backup on hand, now’s the time to ensure your therapy never misses a beat!

Different Types of CPAP Batteries

There are two main types of CPAP battery options: deep cycle batteries (car and boat) and lithium-ion batteries (found in electronics including CPAP machines.

Deep cycle batteries are typically found in auto part stores, are much heavier than lithium-ion batteries, and can be difficult to recharge.

Lithium-ion batteries are the most common CPAP batteries available today and are designed to provide a decent runtime—sometimes powering a CPAP machine for more than one night! They also typically charge quickly, getting up to full power in four to six hours.

Here’s a quick breakdown of the two different types of CPAP batteries:

Deep Cycle:

Lithium-Ion:

  • Not Portable
  • Great for Camping
  • Longer Battery Life
  • Great Portability
  • Use In-Flight
  • Quick Charge

Battery Cost

The cost of CPAP batteries can vary and can depend on what battery works best with your machine. Many CPAP batteries are budget-friendly, costing a few hundred dollars—while others can be close to $900. For a cost-effective option, keep reading to find a universal battery that works with your machine.

Battery Run Time

Most lithium-ion CPAP batteries are designed to last one or two nights under normal operating conditions. However, the run time can vary depending on:

  • Machine Type
  • Higher Pressure Settings
  • Humidification Use
  • Altitude Level
  • Inverter Use

How to Achieve Longer Battery Run Times

To Help Improve Battery Life Try To:

  • Forego Humidification 
  • Avoid Using an Inverter
  • Use an APAP Machine (Can Increase Battery Run Times Since They Are Programmed to Deliver the Pressure You Need at All Times) 

Also, try a travel machine that is made to accompany you on your adventures. It may also help to use a machine-specific battery. For example, the DreamStation Go has the specifically designed, DreamStation Go Overnight Battery. The DreamStation Go is designed to run for 13 hours using the Overnight Battery!

The Best Universal CPAP Batteries

Medistrom Pilot-24 Lite

medistrom pilot-24 lite

The Medistrom Pilot-24 is a top-ranked CPAP battery thanks to its light weight and small size. It’s FAA compliant, meaning you can carry it on and use it during your flight. You’ll also like that it doesn’t require you to be a tech whiz to get it to work with your machine.

You can leave the inverter or companion device at home! Just get the appropriate cord and connect your machine!

The Medistrom Pilot-24 is a long time favorite, but it’s also gained popularity points because of its compatibility with the ResMed AirMini and the ResMed AirSense 10, which are two of the most popular CPAP machines on the market today. It’s also compatible with the:

  • Philips Respironics DreamStation Go
  • ResMed S9
  • 3B Medical Luna
  • Apex Medical iCH

Drawbacks: As a lithium-ion battery, the Pilot-24 can’t tolerate extreme outdoor environments like extremely hot temperatures for extended periods of time. As temperatures rise above 104, the battery will begin to overheat. That’s why it’s a good idea to keep it out of the sun. It also doesn’t come with its own power supply, which means if you want to charge it, you’ll need to use the one that came with your compatible machine. This won’t be a problem if you don’t need the cord for anything else in the process.

CPAP Battery Backup Uses

Campers and hikers unite—your CPAP therapy can travel with you on-the-go!

However, even if you’re not into hiking or camping, having a battery backup on hand that can kick in whenever there’s a sudden loss of power is always a good idea! A major reason behind purchasing CPAP batteries is for the unknown situations—like storm season.

Battery backups integrate seamlessly with most CPAP machines, meaning that the battery knows if the device is or is not receiving AC power. If AC power stops for any reason, the backup kicks on automatically. In most cases, you won’t wake up or notice your machine has switched since it’s automatic.

What’s the Best Battery Backup?

The Freedom V2 Travel CPAP Battery is ideal for a CPAP battery backup. If power is lost, it will automatically kick in, and your therapy won’t miss a beat.

Which CPAP Batteries Are FAA Approved for In-Flight Use?

One of the most popular FAA-approved lithium-ion batteries is the Medistrom Pilot-24 Lite. It’s one of the lightest CPAP batteries around and is compatible with many popular CPAP machines. Lithium-ion batteries are the go-to when it comes to in-flight use! The Freedom V2 and the EXP48 Pro are also approved for in-flight use.

We hope you’re now ready to take your CPAP battery for your machine on your next adventure! Whether you’re hitting the trail or opting for a battery backup, you can’t go wrong by having a battery on hand and ready to go!
