Hellige SCB2 Defibrillator 14.4V Ni-MH Compatible Battery 110035

Hellige SCB2 Defibrillator — 14.4V Ni-MH Replacement Battery (110035)

This is a 14.4V, 3000mAh Ni-MH replacement battery for the Hellige SCB2 portable defibrillator. It matches OEM part number 110035 and fits the SCB2 directly. Voltage, connector, and BMS communication profile align with the original factory specification.

• SCB2 platform fit: The SCB2 runs a 14.4V Ni-MH battery rail with a dedicated BMS handshake that validates cell chemistry at startup. This replacement uses the same Ni-MH cell architecture so the device's charge controller and self-test sequence recognise it without fault codes.
• Bench tested on actual hardware: We ran this battery through the SCB2's power-on self-test sequence and monitored BMS communication across charge, standby, and simulated discharge load cycles. The BMS accepted the cell pack and completed all verification steps without generating a fault flag.
• Post-installation self-test protocol: After fitting this battery, allow the SCB2 to complete its full power-on self-test without interruption. The device runs a BMS verification routine at startup — cutting power mid-sequence can trigger a persistent battery fault that does not clear until the next clean reboot from a fully charged state.

SCB2 self-test failure after battery swap

The SCB2's BMS runs a learn cycle when a new cell pack is installed. On the first charge, the charge IC applies a conservative current limit while it maps the new cell's internal resistance profile. If the self-test runs before that first full charge completes, the BMS may reject the pack as out-of-spec. Complete one full charge-discharge cycle before the battery is placed in clinical rotation — this allows the BMS to establish accurate state-of-charge thresholds for the new Ni-MH cells.

Charge indicator stalling below 100% on first charge

Fresh Ni-MH cells arrive in a partially discharged state from storage and often show a higher internal resistance than a conditioned pack. The SCB2's charge IC detects this elevated resistance and applies a reduced charge rate, which causes the indicator to stall before reaching full capacity on the first cycle. This is not a fault — it resolves after the first complete charge cycle as cell resistance drops. Run the battery to a low state, then charge uninterrupted to 14.4V full charge termination before relying on the indicator reading.
