GE Dash Mini 11.1V Replacement Battery 1850mAh Li-ion

GE Dash Mini / B650 / Carescape PDM — 11.1V Li-ion Replacement Battery (2016989-002)

This 11.1V 1850mAh lithium-ion battery replaces the internal power cell in the GE Dash Mini portable patient monitor and compatible GE monitoring platforms including the B650, B850, and Carescape PDM. It matches the OEM voltage rail and connector spec for these units. Cross-references include part numbers 2016989-002, 2016989-003, M2820, DR203, AMED3709, 6291-A, and 2031069-003.

• Dash Mini / B650 / B850 / Carescape PDM platform fit: These GE monitoring units share a common 11.1V three-cell Li-ion architecture and use the same BMS handshake protocol. A single cell pack revision covers all listed models without modification to the connector or mounting bracket.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a GE-compatible monitor test rig. The BMS initialised correctly, protection thresholds engaged at expected cutoff voltages, and the pack completed a full charge-discharge cycle without fault flags.
• Post-swap power-on self-test: After installing this battery, allow the monitor to complete its full power-on self-test without interruption. GE monitors run a BMS verification sequence at startup — cutting power mid-sequence causes a persistent false battery fault that won't clear until the next full reboot cycle.

Device not completing boot sequence on a freshly installed battery

GE portable monitors run a staged boot that includes a BMS handshake before the main OS loads. A new cell that has partially self-discharged during warehouse storage can sit below the monitor's boot-enable voltage threshold — typically around 10.5V for an 11.1V pack. The device stalls partway through the startup screen and either freezes or powers off. Connect the monitor to mains AC before attempting to power on, let the battery charge for at least 30 minutes, then boot from AC power still connected.

Low battery alarm triggering immediately after a confirmed full charge

This happens because the GE monitor's charge IC compares reported cell capacity against an internal OEM baseline. On a new cell, the BMS hasn't yet built a capacity history, so the state-of-charge estimate runs conservative and the monitor flags a low threshold alarm even at near-full charge. The fix is one complete charge-discharge cycle run outside clinical use — charge to full, allow the monitor to run on battery until it self-terminates, then charge again to 100%. After that cycle, the BMS recalibrates its state-of-charge model and the alarm behaviour normalises.
