Covidien PillCam DR3 Replacement Battery 3.7V 10000mAh

Covidien Pillcam DR3 — 3.7V Li-ion Replacement Battery

This 3.7V, 10000mAh Li-ion battery is a direct replacement for the Covidien Pillcam DR3 capsule endoscopy data recorder. The DR3 is the bedside receiving unit that captures and stores imaging data transmitted by the ingested capsule during small intestine transit. Keeping a charged, cycle-ready battery on hand means procedures are not delayed by a failed or depleted cell.

• Pillcam DR3 recorder platform: The DR3 runs a continuous RF-receive and data-write load for the full capsule transit window. This battery's 37Wh capacity matches the original cell's energy budget for that sustained draw profile, and the connector and BMS communication lines are matched to the DR3's charge management circuitry.
• Bench tested on actual hardware: We cycled this cell through charge, BMS handshake verification, and a sustained low-current draw test replicating the DR3's data-logging load. The protection circuit held cutoff voltage correctly and the charge IC accepted a full charge without fault flags.
• Post-installation self-test requirement: After fitting this battery, allow the DR3 to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at every boot — cutting power mid-sequence stores a false battery fault that persists until the next clean reboot cycle.

Why the DR3 flags a battery fault after a confirmed full charge

The DR3's BMS compares cell impedance and open-circuit voltage against learned thresholds calibrated to the original OEM cell chemistry. A new replacement cell has not yet completed a conditioning cycle, so its impedance profile sits outside the learned window. This triggers a battery-health warning even when state of charge is at 100%. Running one full charge-discharge cycle before clinical use allows the BMS to update its reference values and clear the fault flag.

DR3 will not power on after the battery has been in storage

Li-ion cells self-discharge during storage, and the DR3's BMS has a minimum recovery voltage — typically around 2.5V per cell — below which it will not initiate a boot sequence. If the recorder shows no response when powered on, the battery has likely dropped below that threshold. Place it on charge for at least 30 minutes before attempting to power on the device; the charge IC will apply a low-rate pre-charge trickle until the cell climbs back above the BMS recovery floor. Once the cell exceeds approximately 3.0V, the device will boot normally.
