Biocare iE10 Medical Device Compatible Battery 3.7V 5600mAh

Biocare iE10 — 3.7V Li-Polymer Replacement Battery (PTC5576110)

This 3.7V 5600mAh Li-Polymer battery replaces the OEM cell in the Biocare iE10 portable medical diagnostic device. It matches the original PTC5576110 specification exactly — same voltage, same flat-pack form factor, same connector orientation. Capacity and chemistry are drawn from product data, not estimated.

• iE10 platform fit: The iE10 uses a single flat Li-Polymer cell on a 3.7V rail. The BMS on this device monitors cell voltage at startup and during operation — the replacement cell must match the OEM voltage curve to avoid false fault states during the power-on self-test sequence.
• Bench tested on actual hardware: We ran this cell through the iE10 charge cycle and monitored BMS handshake at startup. The protection circuit accepted the cell without triggering a battery fault flag, and the charge IC brought it to full capacity within the normal charge window.
• Post-install startup procedure: After fitting this cell, allow the iE10 to complete its full power-on self-test without interruption. The BMS runs a voltage verification check at boot — cutting power mid-sequence causes a false battery fault that persists until the next complete reboot cycle.

Why the iE10 alarms low battery immediately after a full charge

The iE10 BMS stores a charge profile calibrated to the OEM cell's internal resistance and discharge curve. A new replacement cell has a slightly different resistance signature in its first few cycles, which can cause the BMS to read state-of-charge conservatively. This triggers a low battery alarm even when the cell is physically full. One complete charge-discharge cycle recalibrates the BMS threshold against the actual cell. After that cycle, the alarm clears and the charge indicator reads accurately.

iE10 not powering on after battery was stored before installation

Li-Polymer cells self-discharge during storage at roughly 2–5% per month. If the cell voltage drops below approximately 3.0V, the iE10 BMS enters a locked state and refuses to initiate startup — this is a protective measure, not a dead cell. Connect the device to mains power and leave it on charge for at least 30 minutes before attempting to power on. The charge IC applies a low-current pre-charge recovery phase to bring the cell back above the BMS recovery threshold. Once voltage clears 3.0V, normal charging resumes and the device will boot.
