OEM-Grade Battery for Apex Concentrators

5-Gear Flow Control Integration

The battery syncs with the concentrator's 1-5 LPM settings through five adjustable power gears. This integration supports personalised oxygen delivery across the device's full flow range. Compatibility is limited to Apex portable models only; users must verify their specific model in the manual before purchase.

Questions about this item

Should I choose the 16-cell 95.5Wh version or a smaller capacity for my Apex concentrator?

The BT035-1 is the single 16-cell 95.5Wh model rated at 14.4V and 6.6Ah. It replaces the exact OEM part number BT035-1 and fits all Apex portable models, so no smaller capacity variant is offered for this unit.

What does the 95.5Wh rating actually deliver when the battery is powering my Apex device?

At a 2 LPM flow setting the 95.5Wh pack provides 8 to 10 hours of runtime, which the manufacturer notes is roughly 20% longer than standard batteries used with Apex concentrators.

Does the 14.4V lithium-ion interface limit the flow rates I can select on the concentrator?

The battery syncs with the Apex unit’s 5-gear flow control covering 1 to 5 LPM settings, so the 14.4V interface supports the full range of adjustable oxygen delivery.
