Heine X-02.99.314 Medical Diagnostic Replacement Battery 3.6V 750mAh

Heine X-02.99.314 / AccuScan-S / NicaTron-S — 3.6V Ni-Cd Replacement Battery (B10097)

This is a 3.6V, 750mAh Ni-Cd replacement cell for Heine diagnostic instruments carrying part number B10097. It fits the X-02.99.314, AccuScan-S, NicaTron-S, and AccuScan platforms. The physical dimensions match the OEM cell at 73.30 × 28.50 × 25.70mm, so it seats correctly in the battery compartment without modification.

• X-02.99.314 platform fit: The AccuScan-S, NicaTron-S, and AccuScan units share the same 3.6V single-cell bay and connector pinout as the X-02.99.314 handle, which is why one cell covers all four models. No adapter or wiring change is needed.
• Bench tested on actual hardware: We charged the cell through a full cycle on the Heine handle and monitored BMS response. The protection circuit accepted the new Ni-Cd chemistry without triggering a fault, and the charge indicator tracked normally through the full charge sequence.
• Power-on self-test behaviour: After installing this cell, let the device complete its full startup self-test without switching it off mid-cycle. Heine diagnostic handles run a BMS verification pass at power-on, and interrupting that sequence can latch a false battery fault that clears only after a full reboot.

Why Heine diagnostic handles run a BMS learn cycle on the first charge

Heine's charge management circuit is calibrated to the OEM cell's charge acceptance curve. A new replacement cell hasn't yet established that reference, so the first charge cycle is effectively a calibration pass. The BMS logs the cell's internal resistance and charge acceptance rate, then uses that data to set cutoff thresholds for subsequent cycles. Skipping a full first charge — or pulling the cell out partway — leaves the BMS without a complete baseline, which causes conservative cutoff behaviour on every charge after that.

Charge indicator not reaching 100% on the first charge after swap

This is a known first-cycle behaviour with Ni-Cd cells in medically regulated chargers. The charge IC applies a reduced current limit on an unrecognised cell until it completes one full charge-discharge pass. On the second charge, the indicator will track normally to 100%. Run a complete charge, use the instrument until the low-battery alert triggers, then charge fully again — after that cycle, the charge display will reflect actual cell state accurately.
