Biocare HYLB-947 ECG-3010 Replacement Battery 14.8V 1600mAh

Biocare ECG-3010 — 14.8V Li-ion Replacement Battery (HYLB-947)

This is a 14.8V, 1600mAh Li-ion replacement battery for the Biocare ECG-3010 and ECG-3010 Digital 3-channel electrocardiograph. It slots directly into the portable ECG unit and restores power to the acquisition module, display, and onboard storage. The HYLB-947 part number matches the OEM specification for this device.

• ECG-3010 and ECG-3010 Digital 3-channel compatibility: Both variants run the same 14.8V battery rail with the same connector and BMS handshake protocol. A single cell covers either unit without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the ECG-3010 platform. The BMS accepted the cell at first insertion, completed the power-on self-test, and held voltage within spec under active ECG acquisition load.
• Post-swap startup procedure: After installing this battery, allow the device to complete its full power-on self-test cycle without interruption. The ECG-3010 runs BMS verification at startup — cutting power during this sequence creates a false battery fault flag that persists until the next clean reboot.

ECG-3010 not completing boot sequence on a new battery

The ECG-3010 runs a BMS learn cycle during its first few charge-discharge passes on a new cell. Until that cycle completes, the device may stall mid-boot or display a battery error even when voltage reads correctly. This is not a fault with the replacement cell — it is the charge IC applying conservative thresholds to an uncalibrated pack. Run one complete charge-to-full followed by a full discharge under normal acquisition use, then recharge fully. After that first cycle, the BMS registers the cell and the boot sequence completes normally.

Charge indicator not reaching 100% on the first charge

On the first charge with a new cell, the ECG-3010's charge IC often caps at 90–95% rather than showing a full charge. The IC is applying a conservative current limit until it has profiled the new cell's internal resistance. This is normal behaviour and not a defective battery. Complete a full discharge and recharge — on the second cycle, the charge indicator will typically reach 100% as the IC recalibrates its end-of-charge threshold to the actual cell chemistry.
