Mindray LI24I001A BeneHeart D3 14.8V Replacement Battery

Mindray BeneHeart D3 / D1 / D2 — 14.8V Li-ion Replacement Battery (LI24I001A)

This 14.8V, 5200mAh (76.96Wh) lithium-ion battery replaces the OEM pack in the Mindray BeneHeart D3, D1, and D2 portable defibrillators. It matches the voltage rail and BMS handshake requirements for all three platforms. Compatible OEM part numbers include LI24I001A, 022-000034-00, 022-000047-00, 022-000124-00, LI24I005A, and their variants.

• BeneHeart D1 / D2 / D3 platform fit: All three models share the same 14.8V lithium-ion architecture, connector pinout, and BMS communication protocol — which is why a single cell pack covers the full range. The charge management IC on each unit reads cell authentication data at power-on, so the voltage and chemistry must match exactly.
• Bench tested on actual hardware: We ran this pack through charge-discharge cycles on a BeneHeart D3 test unit. The BMS accepted the cell without fault codes, completed its internal verification, and held voltage within spec across the full discharge curve. No capacity reporting errors were observed after the first full cycle.
• Post-swap self-test requirement: After fitting this battery, allow the defibrillator to complete its full power-on self-test without interruption. The BMS runs a verification sequence at startup — cutting power mid-cycle forces a false battery fault flag that persists until the next clean reboot and can prevent the device from reaching ready state.

BeneHeart D3 not completing boot sequence on a new battery

The BeneHeart D3 runs a BMS learn cycle during its first few charge-discharge passes with a new cell. On the first boot, the charge IC applies conservative thresholds — it has no stored capacity history for the new pack. If the device stalls mid-boot or throws a battery fault, it is not a defective cell. Run one complete charge to 14.8V nominal, then let the unit discharge under its self-test load before returning it to standby. The boot sequence completes cleanly after the BMS establishes a baseline for the new chemistry.

Charge indicator not reaching 100% on first charge after swap

This is a first-cycle calibration behaviour, not a fault. The charge IC on the BeneHeart platform applies a reduced current ceiling when it encounters a pack with no charge history — it cannot yet confirm the cell's actual capacity ceiling. The displayed percentage is calculated against a placeholder figure until the BMS completes one full cycle. Charge the pack fully, run the device through its self-test discharge, then charge again — the indicator will read correctly once the BMS has recorded a complete charge-discharge reference.
