Check the exact brand and model name on your concentrator. Batteries that look similar may have different connectors, software requirements, or electrical specifications. Call us with the model name before ordering.

Yes, when a compatible external battery charger is available for your model. The charger lets you charge a removed battery separately while the concentrator remains available for use.

Operating time varies by concentrator model, battery size, oxygen setting, breathing rate, battery age, temperature, and operating conditions. Manufacturer estimates are typically based on specific test conditions.

Yes. Rechargeable lithium-ion batteries gradually hold less energy as they age and accumulate charge cycles. Replacing an older battery may restore operating time when the concentrator itself is working normally.

Use only manufacturer-approved batteries, chargers, and power supplies intended for your exact model. Incompatible accessories can cause poor performance, charging problems, equipment damage, or safety concerns.

Batteries and chargers are accessories rather than oxygen-delivery devices. Call us for current ordering requirements, pricing, and model compatibility.
