Description
Quick answer: This is the genuine ResMed external lithium-ion battery for the Astral 100 and Astral 150 ventilators (part 27919, Americas version) — it adds up to 8 hours of run-time per battery for hospital, home, and mobile use. You can connect two external batteries, and combined with the Astral’s internal battery that gives up to 24 hours of continuous power (one external + internal ≈ 16 hours). It’s a life-support backup/mobility power component — used under the patient’s clinical care plan, with appropriate charging and backup arrangements. Because it’s a lithium-ion battery, shipping is regulated — contact us to confirm delivery.
Important — life-support backup power
This battery provides backup and mobility power for a life-support ventilator. For ventilator-dependent patients, uninterrupted power is critical: the external battery is part of the backup-power plan set by the clinical team, alongside mains power, the internal battery, and alarms. Always follow the External Battery and Astral user guides, keep batteries charged, and maintain the backup arrangements your clinical team specifies.

What’s included
- 1 × Astral external battery (Americas, part 27919) — with integrated DC output cable and DC input port
Ventilator, charger/adapter, and mobility bag not included.
About this part
The Astral ventilators run on AC mains, an internal battery, or external batteries — and this external lithium-ion battery extends how long the device can run away from mains power, for hospital, home, and mobile use:
- Up to 8 hours of typical run-time per external battery.
- Stackable — connect a second external battery (its DC output cable into the first battery’s DC input) for more autonomy. The Astral supports up to two external batteries.
- Up to ~16 hours with one external + the internal battery; up to ~24 hours with two external + internal.
- Integrated DC output cable and DC input port — plugs into the Astral’s DC input; the input port lets you charge it or daisy-chain a second battery.
- Charged via the Astral AC adapter or the DC adapter (27925).
It’s designed to pair with the Astral Mobility bag (which holds one external battery) for transport and out-of-home use, giving ventilator patients greater freedom while staying powered.
