What to Look For Before Buying

Choosing a battery requires looking at your machine type and travel style. Watt-hour capacity and FAA compliance are the two most important factors.

Check Verify Machine Compatibility

Check your machine voltage first. Most new units are 24V, but older ones might be 12V. Using the wrong power can cause damage.

Value Assess Your Runtime Needs

Calculate the total hours you need your machine to run. Remember that heated humidifiers and heated tubing consume significantly more power. If you plan to use these features, you will need a battery with a higher watt-hour rating. For multi-night trips, look for linkable batteries.

Rating Confirm FAA Compliance

If you travel by plane, your battery must be under 100Wh to meet most airline regulations. Always carry your battery in your carry-on luggage, as lithium-ion batteries are prohibited in checked bags. Verify the specific requirements of your airline before booking your flight.

Verify Consider Build and Portability

Consider the build. Aluminum cases hold up better on the road. Balance the need for power with how much weight you can carry.
