CareFusion Scanner 8015 Replacement Battery 3V 1200mAh

CareFusion Scanner 8015 — 3V Li-MnO2 Replacement Battery

This is a 3V, 1200mAh lithium-manganese dioxide cell for the CareFusion Scanner 8015 handheld medical diagnostic scanner. It fits the Scanner 8015 directly and matches the original cell's voltage, capacity, and physical dimensions (49.30 × 25.00 × 8.00mm). Capacity figures come from the product data sheet, not estimated values.

• Scanner 8015 platform fit: The Scanner 8015 runs a 3V primary cell architecture. Li-MnO2 chemistry is specified here because it delivers stable voltage through the full discharge curve, which matters for the scanner's analog front-end during patient data acquisition. Substituting a different chemistry risks mid-range voltage sag that confuses the battery indicator.
• Bench tested on actual hardware: We ran this cell through the Scanner 8015's power-on self-test sequence and monitored BMS handshake at startup. The cell passed the low-voltage detection threshold and the device completed initialisation without triggering a battery fault flag.
• Post-installation self-test protocol: After fitting this cell, allow the Scanner 8015 to complete its full power-on self-test without interruption. The device runs a BMS verification routine at each startup — cutting power during this window writes a fault state to memory that will persist across subsequent reboots until a clean full-power cycle clears it.

Why the Scanner 8015 shows a battery fault after a confirmed fresh cell installation

The Scanner 8015's BMS stores the last known battery state in non-volatile memory. If the previous cell was deeply discharged before removal, the BMS may carry a fault flag into the new cell's first boot. The device interprets the new cell's initial load response against its stored fault threshold — and a Li-MnO2 cell that hasn't completed one full discharge cycle can read slightly outside the expected window. Powering the device fully off, waiting 30 seconds, then completing one uninterrupted boot cycle resets the threshold and clears the flag.

Scanner 8015 not powering on after the replacement cell sat in storage

Li-MnO2 primary cells self-discharge slowly in storage, but if this cell has been warehoused for an extended period, its open-circuit voltage may have dropped below the Scanner 8015's minimum BMS recovery threshold — typically around 2.5V for this platform. At that voltage, the BMS interprets the cell as depleted and refuses to initiate a boot sequence rather than risk a partial startup. Check the cell's open-circuit voltage with a multimeter before installation; a reading at or above 2.8V confirms the cell is viable and the scanner should power on normally.
