Oxygen Concentrator Battery FAQ
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.
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.
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)
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.
All batteries are designed for medical-grade reliability, with:
-
Overcharge & over-discharge protection
