Philips 989803174131 Lithium‑ion Module Battery Replacement for IntelliVue MX40 Wearable Patient Monitor

Genuine Philips 989803174131 Battery for IntelliVue MX40 – Reliable Power for Wearable Patient Monitoring

Exact replacement for Philips part number: 989803174131. Compatible with IntelliVue MX40 wearable patient monitor (ambulatory/telemetry).

The Philips IntelliVue MX40 offers ongoing ECG, SpO₂, and vital signs monitoring. You can use it in a general ward, a step-down unit, or during early mobility. This keeps the patient free from tying to a bedside monitor. It’s lightweight, wearable, and designed for freedom. But when the battery starts to fail, that freedom disappears. You get “low battery” warnings after only a few hours, the device shuts down mid-shift, or it won’t hold a charge at all.

The 989803174131 is the factory-spec lithium-ion module battery for the MX40. New, it offers 8–12 hours of continuous monitoring. This depends on parameters, transmission frequency, and usage. After a couple of years of daily charging, capacity drops. You may see runtime cut in half, or the monitor powers off with 30% remaining.

You don’t need to pay Philips’ premium price ($350+). You cannot trust a $50 generic. It might swell, cause error codes, or fail when the patient moves. This new genuine battery provides the same medical-grade reliability as the original. It does this without the extra cost.

Quick Specs – What You’re Getting

A healthy 989803174131 battery restores your MX40 to its original runtime – enough for a full day shift or overnight monitoring without recharging.

OEM vs. Genuine Replacement vs. Cheap Generic – What’s the Real Difference?

Not every battery that fits your MX40 is safe for patient use. Here’s how the three options compare.

 Critical for telemetry units and biomed departments
The MX40 is worn by ambulatory patients. A cheap generic battery can cause sudden shutdowns, leaving a patient unmonitored. It may also swell, damaging the device’s battery compartment. Our genuine replacement meets the same safety and performance standards as Philips’ original.

3 Signs Your IntelliVue MX40 Needs a New 989803174131 Battery

1. Shortened runtime – The monitor used to last a full 12‑hour shift. Now you get “low battery” after 4–6 hours, or it dies mid‑shift.

2. Error messages – The MX40 displays “battery error,” “replace battery,” or fails to power on without being docked.

3. Physical swelling – The module battery looks puffy, doesn’t slide in smoothly, or the case bulges. Replace immediately – a swollen lithium‑ion battery is a fire risk and can damage the monitor.

If your MX40 battery is more than 2–3 years old or showing any of these signs, replace it now. Your patients’ safety depends on uninterrupted monitoring.
