About this replacement
Mindray LI13I001G — 10.8V Li-ion Replacement Battery (LI13I001G)
This 10.8V, 3400mAh Li-ion battery replaces the Mindray OEM part LI13I001G. It fits Mindray portable patient monitoring and diagnostic equipment that runs on this battery platform. Voltage and capacity match the original specification exactly.
- Mindray LI13I001G platform fit: Mindray portable monitors in this family share a common voltage rail and BMS handshake tied to the LI13I001G specification. The connector pinout and communication protocol are consistent across devices using this part number, so the BMS can verify cell state on startup without throwing a fault.
- Bench tested on actual hardware: We ran charge and discharge cycles on this battery against the LI13I001G profile. The BMS completed initialisation, accepted a full charge, and reported state-of-charge accurately after the first full cycle. No false fault codes were triggered during the charge sequence.
- Post-installation self-test protocol: After fitting this battery, allow the device to complete its full power-on self-test without interruption. Mindray monitors run a BMS verification routine at startup — cutting power during this sequence registers a false battery fault that persists until the next clean reboot.
Device not completing boot sequence on a freshly installed battery
Mindray monitors run a BMS learn cycle during the first boot after a battery swap. If the new cell's resting voltage falls below the device's startup threshold — common after storage — the boot sequence stalls before the self-test completes. Connect AC power before powering on, and let the device charge the battery for at least 30 minutes first. This brings the cell above the minimum threshold the BMS requires to clear the boot gate.
Low battery alarm triggers immediately after a confirmed full charge
This happens because the device BMS is calibrated to OEM cell chemistry and applies a conservative state-of-charge threshold on cells it hasn't profiled yet. A new cell reads as partially charged until the BMS has logged one complete charge-discharge cycle to map the cell's actual capacity curve. Run one full charge from depleted to 100% on AC power, then discharge through normal use, and recharge fully. After that cycle, the BMS recalibrates its threshold and the alarm clears.
