R270-7652 / R270-7417 Battery for ResMed Astral 150 Ventilator Ultralife

Genuine Ultralife R270-7652 / R270-7417 Internal Battery for ResMed Astral 100 & 150 Ventilators

Keep your respiratory support system powered with this genuine R270-7652 / R270-7417 replacement battery for the ResMed Astral 150 ventilator. Designed for dependable performance in critical care environments, this high-quality rechargeable battery provides stable power output, consistent runtime, and reliable operation for compatible ResMed ventilator systems.

Built with premium Grade A lithium-ion cells (Ultralife-grade quality), this ventilator battery is engineered to meet strict OEM performance and safety standards. It ensures steady energy delivery for continuous ventilation support, making it suitable for both clinical use and portable patient care scenarios.

Whether used as a replacement or backup battery, the R270-7652 / R270-7417 delivers long-lasting durability, efficient charging performance, and trusted compatibility for professional medical environments.

The Clinical Mandate for Authentic OEM Ventilator Power

In respiratory care, utilizing unverified aftermarket batteries introduces catastrophic risks. A ventilator's Battery Management System (BMS) must calculate remaining runtime down to the precise minute. Substituting authentic medical cells with third-party alternatives can lead to sudden voltage drops, failure to trigger "Critically Low" alarms, and sudden cessation of ventilatory support.

By outfitting your clinical fleet or homecare equipment with this genuine replacement from accessories-mall.com, you guarantee:

• Flawless Alarm Synchronization: Engineered to communicate perfectly with the Astral's internal motherboard, ensuring the “Low Battery” (20 minutes remaining) and “Critically Low Battery” (10 minutes remaining) alarms trigger with absolute accuracy.

• Uncompromised Patient Mobility: Restores the factory-original 8 hours of internal backup power, allowing for safe, extended patient transport and wheelchair mobility without the immediate need for the external RPSII battery system.

• Thermal Stability & Safety: Manufactured by Ultralife to exacting medical standards, these Li-ion cells are chemically stabilized to prevent thermal runaway and overheating during continuous high-pressure ventilation cycles.

• Regulatory & Liability Compliance: Ensures your respiratory equipment remains compliant with strict medical device maintenance protocols (such as ISO 80601-2-12) and preserves the manufacturer’s liability parameters.

Biomedical Engineering Maintenance & Installation Guidelines

To maximize the operational lifecycle of this internal battery and ensure immediate emergency readiness, clinical engineering technicians and homecare providers should implement the following protocols:

1. Initial Hardware Synchronization: Upon physically installing the new R270-7652 battery into the Astral's internal chassis, connect the ventilator to an active AC wall outlet. Allow the device to charge continuously until the on-screen battery icon registers a 100% full capacity. This synchronizes the new battery's microchip with the ventilator's firmware.

2. Continuous AC Connection for Standby Units: When an Astral ventilator is kept as a backup in a clinical equipment room and not actively ventilating a patient, it must remain continuously plugged into a red "emergency" AC outlet.

3. Proactive Replacement Scheduling: Internal ventilator batteries undergo chemical degradation over time, even when primarily running on AC power. To prevent unexpected impedance failures, this internal lithium-ion battery must be proactively replaced according to the timeline dictated by the ResMed Astral clinical service manual (typically every 2 years, or earlier if the device indicates degraded cell capacity).

(Note: Internal battery replacement on life-support ventilators should only be performed by certified biomedical technicians or authorized respiratory equipment providers. Ensure all patient connections are removed and the device is powered down prior to chassis opening.)
