If you’re looking for CPAP battery tips, we have you covered. CPAP batteries are vital to ensuring your therapy runs smooth and sound when you’re on-the-go or if you experience a power outage.
Are you looking to learn how to stop any potential power disturbances in their tracks by having backup CPAP battery options on hand? Are you planning a vacation or a business trip that requires air travel? Many CPAP machines are approved for in-flight use, which means your therapy can be used in the air.
If you’re looking to go camping or spend a weekend in the wilderness, don’t leave your CPAP therapy at home. Many CPAP machines have battery options that you can use to power your machine when you’re nowhere near an AC power outlet. Even solar panels can be used to power your machine when you’re enjoying your time in the great outdoors. Yes, you read that right!
From going off-the-grid to traveling via air, we have the CPAP battery tips and tricks for ensuring your therapy has no interruptions!
Tip 1: CPAP Battery Backups Are Recommended
Even if you’re not into hiking, camping, or going off-the-grid, it is still recommended to have a backup CPAP battery. Some CPAP batteries can be used as a backup that will kick in whenever there’s a sudden loss of power—ideal if you notice a storm on the forecast. In fact, the battery backup feature is why many people purchase additional or alternative batteries in the first place because you shouldn’t have to be without your therapy.
Backup batteries integrate seamlessly with most CPAP machines, meaning that the battery knows if the device is getting AC power or not. 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. It’s automatic!
Tip 2: Many CPAP Batteries Are FAA Approved for In-Flight Use
Flying across the country or around the world can cause worry among CPAP users who don’t want to miss out on the benefits of CPAP therapy while traveling the globe. For frequent travelers, we have great news! Many CPAP batteries are approved for in-flight use and can be used to safely power your CPAP machine while you travel to your next destination.
Many of the batteries are lightweight and ultra-portable so fitting them inside your carry-on bag will be a breeze. You can finally sleep on even your longest flights and get to your destination feeling refreshed and awake. If you fly often, a travel CPAP machine may also be useful for your adventures.
Tip 3: CPAP Batteries Can Adapt to Harsh Conditions
Many batteries are designed to work in even the harshest conditions, including a trek through the Himalayas! In an article published by the medical journal, High Altitude Medicine and Biology, researchers wanted to test whether or not a CPAP machine could be used to treat altitude sickness.
Researchers sent a group of mountain climbers on a trek through the Himalayas with a CPAP machine and a battery system. They ran tests to see if CPAP machines could treat altitude sickness. The study found that CPAP machines helped reduce the symptoms of altitude sickness amongst the climbers, which means if you’re taking on the challenge of hiking in high altitudes, take your therapy with you.
This means the benefits of your therapy can be experienced while you’re on-the-go. All you need is the necessary tools to adjust to your weather conditions. When you’re away from the comforts of your own home, have confidence that your battery is as rugged as you need it to be and be confident as you take it with you off-the-grid.
Tip 4: Machine Type and Pressure Settings Can Impact Battery Run Time
The biggest question people ask about CPAP batteries is how long their machine will run with a specific model of battery. Unfortunately, battery runtimes vary widely from one machine to another. Things like your pressure settings and whether or not you’re using humidification can all play a role in battery run times. As a basic rule, run times are generally reduced at higher pressure settings and altitudes, when using humidification, and if you’re using an inverter.
Now, are you asking how can you get longer battery run times?
First of all, you could forego humidification when you’re using a CPAP battery. Second, you may find that using an APAP machine can be beneficial in helping increase battery run times since APAPs are programmed to deliver exactly the pressure you need at all times.
If you need your machine to run for longer periods of time, adjusting the machine you use or the pressure settings can increase your battery run time.
Let’s dive into some CPAP battery facts to help you pick the right one for your machine or your therapy needs.
There Are Two Main Types of CPAP Batteries
There are two main types of batteries: Lithium-ion batteries and deep cycle batteries. Lithium-ion batteries are the most common CPAP batteries available today. These batteries are typically found within most electronics, including CPAP machines. While on the other hand, deep cycle batteries are found in cars and boats.
Lithium-ion batteries are designed to provide a decent runtime by powering a CPAP machine for one night or more depending on the battery. These batteries also usually charge quickly, getting up to full power in four to six hours.
In order to connect to the deep cycle batteries, you can use an inverter. You’ll use alligator clips to connect to the positive and negative terminals, and then plug in your machine like you normally would.
It’s also possible to make a connection to the terminals with a normal cigarette-style outlet for machines that don’t need an inverter. You would then charge the battery using a DC cable.
If you’re looking for a light and simple option for a battery backup, we recommend a lithium-ion battery.
Some Machines Require an Inverter to Connect to the Battery
Some machines can connect directly to a compatible battery for power, while other machines will require the use of an inverter. An inverter is a device that’s used to convert the DC current found in batteries to the same AC current that comes out of the wall. You would plug your CPAP machine into the inverter using the same plug you use for the wall. Inverters come in handy while on a road or camping trip using a vehicle.
Certain machines specifically call for a Sine Wave inverter. A Sine Wave inverter is a special type of inverter that purifies the power output from the battery so that it’s almost an exact match to the power supplied by a wall socket. If your machine calls for a Sine Wave inverter, then it’s important you use one. Using a regular inverter when a machine calls for a Sine Wave inverter can cause damage to your CPAP machine so be sure you have the right equipment!
Overall, whether you’re traveling by foot, air, car, boat, or RV, there are options to ensure you can stick to your therapy while you’re on-the-go.
