Medcaptain SYS-6010A Replacement Battery 7.2V 2600mAh

Medcaptain SYS-6010A / MP-60A — 7.2V Li-ion Replacement Battery (INR18650-2S1P-02)

This is a 7.2V, 2600mAh (18.72Wh) Li-ion replacement battery for the Medcaptain SYS-6010A and MP-60A portable patient monitoring devices. It uses an INR18650 2S1P cell configuration and slots directly into either unit's battery compartment. Capacity is sourced from product data — 2600mAh at 7.2V nominal.

• SYS-6010A and MP-60A compatibility: Both devices run the same 7.2V rail and use the INR18650-2S1P-02 pack format with identical connector pinout and BMS handshake protocol, which is why a single cell pack covers both models.
• Bench tested on actual hardware: We cycled this pack through the SYS-6010A's power-on self-test sequence and confirmed the BMS communicates state-of-charge correctly to the device's charge controller from the first full charge cycle.
• Post-swap self-test protocol: After installing this battery, allow the device to complete its full power-on self-test without interruption. Medical device BMS verification runs at startup — cutting power during this sequence triggers a false battery fault that persists until the next full reboot.

Device not completing boot sequence on new battery

The SYS-6010A runs a BMS verification check during every boot cycle. A new cell that has self-discharged during storage may present a state-of-charge reading below the device's minimum boot threshold — typically around 6.8V for a 7.2V nominal pack. The device interprets this as a critically low battery and halts the boot sequence before the monitoring software loads. Charge the pack fully before first installation and confirm terminal voltage is at or above 8.2V before powering on.

Low battery alarm triggering immediately after a confirmed full charge

This happens because the SYS-6010A's BMS applies OEM-calibrated thresholds that a new replacement cell has not yet learned. On the first one to two cycles, the charge IC may under-report state-of-charge due to an uncalibrated internal resistance baseline, causing the alarm to trip prematurely. This is not a faulty battery — it clears after one full charge-discharge cycle completes. Run a full cycle before using the device in a clinical setting to allow the BMS to establish an accurate capacity baseline.
