Haier 7G-5H Replacement Battery 14.8V 2600mAh 91672232H

Haier 7G-5H Series — 14.8V Li-ion Replacement Battery (91672232H)

This is a 14.8V, 2600mAh (38.48Wh) lithium-ion battery for the Haier 7G-5H notebook series, including the 7G-5HI54200UG40500NDTS, 7G-5HI745G40500NDTS, and 7G-5HT variants. It replaces OEM part numbers including 91672232H, SQU-1309, SQU-1303, and CQB924 across the compatible range. If your original cell no longer holds a charge or the laptop won't run off battery at all, this is the direct cell swap.

• 7G-5H platform compatibility: All listed 7G-5H variants share the same 14.8V four-cell battery architecture, connector pinout, and BMS communication protocol — which is why a single cell covers the full lineup without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the 7G-5H platform. The BMS handshake completed without fault codes, charge current ramped correctly from CC to CV phase, and the protection circuit tripped at the expected low-voltage threshold with no anomalies.
• Post-install calibration on the 7G-5H: After fitting this cell, run one full discharge until the laptop hibernates on its own, then charge uninterrupted to 100% without interruption. This forces the Haier BIOS to complete its battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.

BIOS reporting battery health as poor immediately after fitting a new cell

The Haier 7G-5H reads health data from EEPROM registers on the battery's fuel gauge IC, not from real-time voltage measurements alone. When a new cell goes in, those registers still reflect the degraded state of the old unit until a calibration cycle overwrites them. The BIOS flags "poor health" or a reduced Wh rating because it hasn't yet mapped the new cell's actual charge curve. Run one full discharge to hibernate cutoff, then a full uninterrupted charge to 100% — after that cycle the BIOS figures update and the warning clears.

Laptop shuts down at 20–30% shown on the fuel gauge

This happens when the OS fuel gauge IC hasn't been calibrated against the new cell's voltage-to-capacity curve. The gauge thinks 20% remains but the cell voltage has already dropped below the BMS cutoff threshold under combined CPU and display load. The result is an abrupt shutdown rather than a graceful low-battery sequence. Complete two full discharge-to-hibernate then full-charge cycles — by the second cycle the gauge should track accurately down to the BMS cutoff at approximately 11.0V under load.
