Critikon Dinamap Plus 8710 EPP-100C Replacement Battery 14.4V

Critikon Systems Dinamap Plus 8710 Series — 14.4V Li-ion Replacement Battery (EPP-100C)

This is a 14.4V, 4400mAh lithium-ion battery built to OEM part number EPP-100C. It fits the Critikon Systems Dinamap Plus 8710, 8720, and 8725 non-invasive blood pressure monitors used in clinical and hospital settings. Voltage and capacity match the original specification exactly.

• 8710, 8720, and 8725 compatibility: All three Dinamap Plus models share the same 14.4V power rail, connector pinout, and BMS handshake protocol, which is why a single cell covers the full range. The charge IC on each monitor expects the same chemistry signature and cutoff thresholds.
• Bench tested on actual hardware: We cycled this cell on a Dinamap Plus 8720 under a simulated clinical load profile. The BMS accepted the new cell without fault flags, completed the charge cycle cleanly, and held voltage within the expected band across repeated measurement sequences.
• Post-installation self-test protocol: After fitting this battery, allow the monitor to complete its full power-on self-test without interruption. The Dinamap Plus runs a BMS verification sequence at startup — cutting power mid-cycle triggers a false battery fault that persists until a clean reboot is performed.

Why the Dinamap Plus reports a battery fault after a confirmed full charge

The Dinamap Plus BMS stores calibration thresholds tuned to the aged chemistry profile of the original cell. A new cell presents a slightly different internal resistance and charge curve, which the BMS can misread as an out-of-spec pack on the first cycle. This does not mean the battery is faulty. Run one complete charge-discharge cycle through the device, then recharge to 100% — the BMS recalibrates its thresholds and the fault clears. If the fault persists beyond the second full cycle, check the connector seating and confirm terminal voltage reads 14.4V at the pack.

Charge indicator stops below 100% on first charge

On the first charge of a new Li-ion cell, the Dinamap Plus charge IC applies a conservative current limit while it profiles the pack's internal resistance. This causes the indicator to plateau short of 100% and stall for an extended period before completing. The cell is still charging — this is normal first-cycle behaviour, not a fault. Leave the monitor on charge until the indicator clears; subsequent charges complete to full capacity without this delay.
