What to Look For Before Buying
Choosing a battery depends on your machine and where you are going. Think about the capacity you need for your pressure settings. Always check TSA rules if you plan to fly.
Check Verify Compatibility
Check that the battery comes with the right cable for your machine. Not all units use the same DC input.
Value Assess Capacity Needs
Calculate your nightly power consumption by looking at your machine’s specs. If you use a humidifier, you will need significantly more capacity. Most batteries indicate runtime based on having humidification disabled. Always plan for extra capacity to be safe.
Rating Check TSA Compliance
Airlines limit lithium batteries to 100Wh for carry-on luggage. Some may allow up to 160Wh with airline approval. Always verify the capacity before booking a flight. Do not risk bringing an oversized battery to the airport.
Verify Look for Safety Features
Ensure the unit has a built-in Battery Management System. This protects against overcharging, short circuits, and overheating. A high-quality BMS is non-negotiable for medical device backup. Safety should always be your top priority.
