About this replacement
Philips Ultrasound CX30 / CX50 / EPIQ 5 — 14.8V Li-ion Replacement Battery (453561446191)
This 14.8V 6150mAh (91.02Wh) Li-ion battery replaces the original power pack in the Philips CX30, CX50, Echographe CX50, and EPIQ 5 portable ultrasound systems. It matches the OEM voltage rail and connector configuration those platforms require. Compatible part numbers include M6477, 453561446192, and 453561268715.
- CX30, CX50, and EPIQ 5 platform compatibility: These models share the same 14.8V four-cell battery architecture, BMS handshake protocol, and locking connector format. A single cell pack services all four variants without modification.
- Bench tested on actual hardware: We cycled this battery through full charge and discharge on the CX30 platform. The BMS completed its authentication handshake, accepted charge from the internal charge IC, and held voltage above the 13.5V cutoff threshold under continuous imaging load.
- Post-installation self-test cycle: After fitting this battery, let the ultrasound unit complete its full power-on self-test without interrupting or powering down mid-sequence. The CX30 and CX50 run a BMS verification routine at startup — cutting power during this sequence registers a battery fault that persists until the next clean reboot.
CX30 not completing boot sequence on a new battery
The CX30 runs a multi-stage self-test at startup that includes a BMS handshake and a minimum voltage check. A new cell that has partially self-discharged during storage may sit below the threshold the device expects at boot, causing the sequence to stall or abort. This is not a faulty battery — it is a state-of-charge issue. Connect the unit to mains power first, allow the battery to reach at least 80% charge, then attempt a cold boot.
Charge indicator stalls below 100% on first charge
On the first charge cycle, the CX50 and EPIQ 5 charge IC applies a conservative current limit to new cells it has not yet profiled. This is normal behaviour — the charge controller is running a capacity-learning pass, not reporting a fault. The indicator typically stalls between 85–95% for 20–40 minutes before completing. Run one full charge-to-discharge cycle before relying on the charge display for clinical scheduling.
