New Genuine 989803190371 4ICR19/66-2 5000mAh Battery Replacement for Philips Efficia DFM100 Monitor Defibrillator

Genuine Efficia DFM100 Battery – 989803190371, 4ICR19/66‑2, 5000mAh

Exact replacement for Philips part number 989803190371 (cell type 4ICR19/66-2). The Philips Efficia DFM100 defibrillator/monitor may use this battery. With a large 5000 mAh capacity, it provides longer operating time.

In critical care transport, the emergency department, or during a code blue, your team relies on the Philips Efficia DFM100. It’s essential for defibrillation and monitoring vital signs. But this confidence could start to fade as the battery starts to run low on power. Early "low battery" alarms can happen. The device might turn off suddenly while moving. It may also not hold a charge at all.

The original lithium-ion battery created for the Efficia DFM100 is the 989803190371. Made with top-quality 4ICR19/66-2 cells, it provides 5000mAh of dependable power. This ensures hours of continuous monitoring and multiple defibrillation shocks. With constant use over time, battery capacity drops. Therefore, getting a new, real replacement is absolutely necessary.

It is unnecessary to spend over $450 on Philips' exorbitant pricing. Avoid cheaper options priced around $60. They might expand, show error messages, or fail during an emergency. This new real battery matches the original's medical-grade reliability, but it costs less.

3 Signs Your Efficia DFM100 Needs a New Battery

1. Shortened runtime – The device used to last a full shift or multiple transports. Now you get “low battery” warnings after only 1–2 hours of monitoring.

2. Error messages – The DFM100 displays “battery error,” “replace battery,” or fails to complete self‑test.

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

If your battery is more than 2–3 years old or showing any of these signs, replace it now. Your patients’ lives depend on a ready defibrillator.
