About this replacement
Philips IntelliVue MP2 / X2 — 10.8V Li-ion Replacement Battery (M4607A)
This 10.8V, 2600mAh Li-ion battery replaces the M4607A cell in the Philips IntelliVue MP2 and X2 portable patient monitors. It also fits the M3002A and M8102 platforms. Voltage and capacity match the OEM specification exactly.
- MP2, X2, M3002A, and M8102 compatibility: These models share the same 10.8V battery bay, connector pinout, and BMS handshake protocol. One cell fits all four platforms without modification.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the IntelliVue platform. The BMS accepted the new cell, completed its verification sequence, and reported correct state-of-charge on the monitor display. No fault codes triggered after a full charge-discharge cycle.
- Power-on self-test protocol: After installing this battery, let the MP2 or X2 complete its full startup sequence without interruption. The monitor runs a BMS verification check at boot. Interrupting that sequence can latch a false battery fault that persists until the next complete reboot cycle.
Why the IntelliVue MP2 reports a battery fault on a brand-new cell
The MP2's BMS compares the new cell's chemistry signature against stored OEM reference thresholds. A fresh cell that hasn't completed one full charge-discharge cycle often reads outside those thresholds, triggering a fault flag. This is a calibration gap, not a defective cell. Run one complete charge to 100%, then discharge under normal clinical load — the BMS updates its reference data and clears the fault on the next boot.
Charge indicator stuck below 100% after first full charge
On first charge, the IntelliVue charge IC applies a conservative current limit to an uncharacterised cell, which can cause the display to plateau at 85–95% and stall. This is the charge controller protecting against an unknown cell, not a capacity problem. Disconnect the charger, power the unit on, allow a partial discharge, then recharge fully. After one full cycle the charge IC recognises the cell's internal resistance profile and the indicator reaches 100%.
