What Should I Consider When Buying a CPAP Battery?

When buying a CPAP battery, several factors must be considered to ensure it meets your needs and preferences. Here are some key considerations: 

  • •Compatibility: Ensure the CPAP battery is compatible with your specific CPAP machine model. Not all batteries work with every device, so check for compatibility information provided by the battery manufacturer.
  • •Power Capacity: Consider the battery's capacity, usually measured in watt-hours (Wh). Higher capacity batteries generally provide longer runtime.
  • •Portability: If you travel frequently or plan to use your CPAP machine on the go, choose a lightweight, portable battery and, if flying by air, ensure it is FAA-approved.
  • •Charging Options: Look for batteries that offer multiple charging options. Some batteries use AC or DC power (car adapter).
  • •Charging Time: Consider the charging time required for the battery. Faster charging options may be more convenient, especially if you have limited time between uses.
  • •Extra Features: Some CPAP batteries have extra features such as built-in flashlights, USB ports for charging other devices, or indicator lights displaying the battery's status. Evaluate these features based on your preferences and needs. 

How Long Will a CPAP Battery Last?

In general, a fully charged portable battery can power a CPAP machine for anywhere from 8 to 24 hours. The time a battery can power a CPAP machine depends on the battery's capacity, run time, and use of a CPAP humidifier.

Will Insurance Cover a CPAP Battery?

Most insurance providers don't cover CPAP batteries because they don't consider them necessary for CPAP therapy. However, some insurance plans may cover or partially cover CPAP batteries. Check with your insurance company and be ready to provide medical proof showing that you require a CPAP machine.

Summing Up

Beyond being a mere convenience, CPAP batteries are crucial and dependable additions to your CPAP toolkit. This is particularly true if you reside in regions prone to power outages or are a frequent traveler. Investing in a CPAP battery guarantees the uninterrupted continuity of your CPAP therapy, providing peace of mind and maintaining your commitment to consistent sleep apnea management.

Take your pick from the best portable CPAP batteries mentioned above, and you won't need to risk skipping your sleep therapy sessions due to power issues ever again!
