Frequently Asked Questions (FAQs)

How long does the battery last on one charge?

The battery provides up to 6 hours at lower levels. Levels 3-4 provide around 2-3 hours, while Level 5 provides about 1-1.5 hours. Runtime also depends on the selected mode and battery condition.

Can I charge the battery without the concentrator?

Yes. The battery has a built-in USB-C charging port. This lets you charge it separately while another battery remains connected to the concentrator. A complete charge takes approximately 3-4 hours.

Is this battery compatible with every concentrator?

No. This battery is made specifically for the 1-5L Portable Oxygen Concentrator sold on this website. Check your concentrator model before ordering because it may not fit devices from other brands or product ranges.

How quickly can I replace the battery?

A battery change usually takes around 5-10 seconds. Press the one-press release, slide out the current battery, and insert the charged replacement. Make sure the new battery sits securely before restarting the concentrator.

Should I carry a second battery?

A second battery is useful for longer outings or limited access to power. Two fully charged batteries can provide up to 12 hours when used one after another, based on the selected level and operating mode.

How should I care for the battery?

Keep the battery dry and away from strong heat, freezing temperatures, and direct sunlight. Recharge it before longer outings. Stop using the battery if its case becomes cracked, swollen, damaged, or unusually hot.
