Biocare iE3000 HYLB-1994 Replacement Battery 11.1V 2600mAh

Biocare iE3000 / iE101 — 11.1V Li-ion Replacement Battery (HYLB-1994)

This is an 11.1V 2600mAh (28.86Wh) lithium-ion battery for the Biocare iE3000 and iE101 portable medical diagnostic instruments. It replaces OEM part numbers HYLB-1994 and 02030046. Physical dimensions are 68.60 × 55.20 × 18.60mm — confirm these against your existing cell before fitting.

• iE3000 and iE101 compatibility: Both models run the same 11.1V three-cell series architecture with an identical connector pinout and BMS handshake protocol. One battery covers both platforms without modification.
• Bench tested on actual hardware: We cycled this cell through full charge and discharge on the iE3000 platform and confirmed the BMS accepted the cell, passed the charge-complete flag, and held voltage within spec under the device's diagnostic load profile.
• Power-on self-test after installation: After fitting this battery, let the iE3000 or iE101 complete its full startup self-test without interrupting power. Medical device BMS firmware runs a battery verification routine at boot. Cutting power mid-sequence flags a persistent battery fault that will not clear until the next clean reboot.

Why the iE3000 rejects a new battery during self-test

The iE3000's BMS uses a learned capacity threshold set against OEM cell chemistry. A fresh replacement cell has not yet completed a full charge-discharge cycle, so its reported state-of-charge profile does not match the stored baseline. The device interprets this mismatch as a fault and may display a battery error or refuse to proceed past the self-test screen. Running one complete charge cycle — to full charge termination, then to normal discharge cutoff at approximately 9V — writes the correct capacity data to the BMS and clears this condition.

Charge indicator stuck below 100% after fitting a new cell

On first charge, the iE3000's charge IC applies a conservative current limit to an unrecognised cell, which causes the charge cycle to terminate early before the cell reaches full capacity. The indicator reads 85–95% and stops climbing. This is a charge IC protection behaviour, not a faulty battery. Connect the device to mains power and allow a second full charge cycle — the IC adjusts its termination threshold once it has profiled the new cell, and the indicator will reach 100%.
