What are the best CPAP batteries you should get for your machine? Finding the right product is so essential since you probably depend on this machine to help with your obstructive sleep apnea and get quality sleep. Below we reviewed five excellent batteries that will charge your device and keep it running.

Types of CPAP Batteries

There are two common types of these batteries, and below, you can find out why they’re different, the pros, cons, and how you can use them.

Deep Cycle

Deep cycle batteries are usually found in auto repair shops and are more complicated to use. If you want to charge these batteries, you need a machine called an inverter, and they take longer until they’re fully charged. One of the advantages of deep cycle batteries is that they’re more powerful but are heavier. These batteries are common in mobility scooters, boats, etc.


Lithium-ion batteries are the ones most people use for modern electronic devices. They are great for air travel since they’re much lighter and straightforward to use. They’re also suitable to take with you anywhere you go. Lithium-ion batteries charge faster but are less powerful than deep cycle. In addition, these batteries are more affordable, and you can use them for many charges.

What to Consider When Purchasing A CPAP Battery

When shopping for your new portable battery, there are a few factors to remember. Below you can find an in-depth shopping guide to help you choose the best product.

Battery Capacity

Your battery's capacity is measured in milliamps per hour or watts per hour, and the bigger the capacity, the longer the battery will run after charging. Most people opt for a battery with a higher capacity since they don’t want to charge it as often and want it to last longer.


Most batteries include a 1-year warranty, and it’s very rare that you find a product with a 2-year warranty. Generally, this warranty refers to a faulty battery but won’t cover damage from use. If you find a product with a long warranty covering more than this, you should also review its other features and consider if it’s a good fit for your machine. In addition, most insurance companies don’t cover the cost of these batteries, so you should focus on getting a high-quality product with a decent warranty.


Most of these batteries are compact, and you can carry them with you; however, some are smaller and lighter than others. So before you decide which one to buy, you should check its weight and dimensions. For example, if you plan on taking it with you on a camping trip, you should pick a lightweight version.

Charging Time and Run Time

The battery runtime depends on various factors, including the pressure setting, altitude level, your machine, the use of a humidifier, and more. Most of these products will last for one to two nights per single charge.


Not all batteries are compatible with every machine type. Therefore, you should see the type of battery compatible with your CPAP device before even looking at reviews. Most manufacturers produce batteries that work for the medical devices from the same brand; therefore, you have to do your research first. If you buy a battery that’s not suitable for your device, it can damage the machine, and it might not power it at all.

Are you ready to pick your next battery? We hope that this guide helped you understand the features of these devices and how to find the best for your CPAP machine.
