Medtronic Ovidien Pillcam DR3 Compatible Battery 3.7V 10000mAh

Medtronic Ovidien Endoscope Pillcam DR3 — 3.7V Li-ion Replacement Battery (BAT-0023-SP)

This 3.7V Li-ion battery replaces the BAT-0023-SP cell in the Medtronic Ovidien Endoscope Pillcam DR3 capsule endoscopy system. It fits the DR3 recorder unit that powers camera capture and wireless transmission during gastrointestinal imaging procedures. Capacity is 10000mAh (37Wh), matching the original cell specification.

• Pillcam DR3 recorder compatibility: The DR3 recorder uses a single-cell 3.7V Li-ion configuration with a BMS that verifies cell chemistry and voltage signature at startup. This replacement matches that voltage rail and connector pinout so the recorder's charge management circuit recognises the cell correctly.
• Bench tested on actual hardware: We cycled this battery through the DR3 recorder's full charge and discharge sequence. The BMS accepted the cell without fault codes, completed charge handshake normally, and held stable voltage under the recorder's wireless transmission load.
• First-use self-test protocol: After installation, let the DR3 recorder complete its full power-on self-test without interrupting or removing power. The recorder's BMS runs a cell verification routine at startup — cutting power mid-sequence logs a battery fault flag that persists until the next clean reboot.

Why the DR3 recorder trips a low-battery alarm with a fully charged replacement

The DR3's BMS stores a learned capacity model from the previous cell. On first installation of a new battery, the recorder compares the new cell's discharge curve against that stored profile. Until one complete charge-discharge cycle recalibrates the BMS, the recorder may read state-of-charge inaccurately and trigger a low-battery warning even at full charge. Run one full cycle — charge to 100%, allow normal discharge, then recharge — before clinical use. After that cycle, the BMS updates its model and alarm behaviour normalises.

DR3 recorder fails to power on after the replacement battery sat in storage

Li-ion cells self-discharge slowly during storage. If the replacement battery rested in a warehouse long enough, its resting voltage may have dropped below the DR3 recorder's BMS recovery threshold — typically around 2.5V per cell — at which point the BMS blocks power-on as a protection measure. Connect the recorder to its charger and leave it for a minimum of 30 minutes before attempting to power on. This allows the charge IC to push the cell above the recovery threshold and re-enable the BMS output. If the recorder still does not respond after 30 minutes on charge, check charger output voltage at the connector.
