Replacement Battery for HeartStart MRx

This lithium-ion battery delivers 97 Wh at 14.4 V and is built to power the Philips HeartStart MRx defibrillator. It replaces original part numbers M3535A, M3536A and M3538A as well as cell reference 4ICR19/66-3. The pack ships new in white and includes a three-month parts guarantee.

Clinical Teams Needing a Direct Swap

Biomedical engineers and emergency-response crews who maintain HeartStart MRx units with ECG, SpO2 and blood-pressure monitoring will find this a like-for-like replacement. Facilities that use other defibrillator platforms or require a different voltage or chemistry should source a pack matched to their specific device.

Fits Into Existing Service Workflow

The battery slots into the MRx battery compartment without adapters or firmware updates, restoring full portable operation for patient transport and code response. No extra chargers or cabling are required beyond the standard MRx docking station already in use.

Questions about this item

Does my HeartStart MRx defibrillator need any special firmware before I install this 14.4V 97Wh battery?

No firmware update is required; the battery is a direct replacement for part numbers M3535A, M3536A and M3538A and works with the MRx defibrillator as supplied.

Will the battery still power ECG, SpO2 and BP monitoring if I keep an older M3535-60992 module in the same MRx unit?

Yes, the 97Wh lithium-ion pack supports all MRx functions — ECG, SpO2 and BP — alongside legacy modules such as the M3535-60992.

How can I confirm the new battery is recognised and holding a full charge after I fit it?

Insert the battery, power on the MRx and check the on-screen battery indicator; it should show a full charge and the ready light will illuminate when the self-test passes.
