Oxygen Concentrator Battery FAQ

What types of batteries are used in oxygen concentrators?

Most portable oxygen concentrators use rechargeable lithium-ion batteries due to their high energy density, long cycle life, and lightweight design. Compared with lead-acid or NiMH, lithium-ion batteries provide longer run times and faster charging, which are critical for medical applications.

How long can an oxygen concentrator run on a single battery?

Battery runtime depends on capacity and oxygen flow settings.

  • A standard 6–8 cell lithium-ion pack usually powers the device for 2–4 hours.

  • Extended battery packs can provide up to 8–10 hours of operation.
    As a factory, we can customize capacity (e.g., 4Ah, 6Ah, 9Ah, etc.) according to client requirements.

Can your factory customize batteries for different oxygen concentrator models?

Yes. We offer OEM & ODM battery solutions for oxygen concentrators, including:

  • Voltage & capacity customization (e.g., 14.8V/6.6Ah, 25.9V/9Ah)

  • Battery housing and connector design

  • Smart BMS (Battery Management System) with protections (overcharge, over-discharge, short circuit, temperature control)

How long does it take to charge a concentrator battery?

Charging time typically ranges from 2 to 4 hours, depending on charger specifications and battery capacity. We can provide fast-charging battery packs to reduce downtime, especially for patients requiring continuous therapy.

What safety features are included in your batteries?

All batteries are designed for medical-grade reliability, with:

  • Overcharge & over-discharge protection

  • Short-circuit protection

  • Over-temperature cutoff

  • Cell balancing for stable output

  • Compliance with UN38.3, CE, IEC, and RoHS certifications for international shipment and medical device standards
