Beisite REF R270-7652 4INR19/66-3 95Wh 14.4V ventilator battery

Replacement Battery for ResMed Astral Ventilators

This 95Wh 14.4V lithium-ion unit replaces part numbers REF R270-7652, 4INR19/66-3, REF R270-366/1 and REF R270-7417. It is built for the ResMed Astral 100 and 150 series ventilators that rely on the Ultralife form factor. Clinical teams and home-care providers use it as a direct swap when the original pack reaches end of life.

Sustained Runtime on Ventilator Load

The 95Wh capacity feeds the Astral 100 or 150 continuously through extended therapy sessions without the voltage sag seen in lower-rated packs. Internal cell balancing maintains stable output across the full discharge curve so the ventilator receives consistent power until the battery management system signals depletion. This behaviour supports overnight or transport use where a short-burst rating would be misleading.

Thermal and Power Characteristics

Lithium-ion chemistry keeps heat generation low during normal discharge at 14.4V, so the pack stays within safe temperature limits inside the ventilator’s battery bay. No active cooling is required and acoustic noise is absent because there are no moving parts. The black housing matches the original Ultralife aesthetic while meeting the electrical demands of the Astral 100 and 150 platforms.
