Purpose-built replacement battery

This lithium-ion pack is engineered specifically for AirSep Freestyle 3 and Freestyle 5 portable oxygen concentrators. It replaces original part numbers BT015-1 and BT018-1S with 100 percent OEM compatibility. The 14.8 V, 3.6 Ah unit delivers 53.28 Wh of capacity in a black housing measuring 136.40 by 50.70 by 24.60 mm.

Steady output for continuous therapy

The cell chemistry maintains a stable 14.8 volt rail throughout the discharge curve, so the concentrator receives consistent power during extended daily use. Rated at 3600 mAh, the pack supports multi-hour sessions away from mains power without the voltage sag that can trigger device alarms. Li-ion construction also means low self-discharge between therapy days.

Upgrade from depleted or ageing originals

Users whose factory batteries no longer hold a full charge will regain the full rated runtime this 53.28 Wh pack provides. The jump is worth it when the concentrator shuts down prematurely or signals a battery fault, restoring the mobility the Freestyle 3 and 5 were designed for. Buyers needing higher capacity than 3.6 Ah or a different voltage platform cannot use this model.

What must I already own for this DS-CS-SPF300MD battery to work?

You need an AirSep Freestyle 3, Freestyle 5 or compatible Caire portable oxygen concentrator that accepts the original BT015-1 or BT018-1S battery.

Will this replacement battery fit and charge correctly in my older Freestyle 3 that still uses the original BT015-1 pack?
