About this replacement
Honor MagicBook 14 i7-1165G7 — 7.64V Li-Polymer Replacement Battery (HB4792Z9ECW-22A)
This is a 7.64V, 7330mAh (56Wh) lithium-polymer replacement battery for the Honor MagicBook 14 i7-1165G7 laptop. It also fits the MagicBook X14 and models NDR-WFH9HN and NMH-WFQ9HN. Install it when the original cell no longer holds charge, reports degraded health, or fails to power the machine away from mains.
- MagicBook 14 and X14 platform fit: These models share the same battery bay dimensions, 7.64V two-cell configuration, and HB4792Z9ECW-22A connector pinout. The BMS handshake uses the same EEPROM protocol across this platform, so the BIOS reads the replacement cell without adapter modification.
- Bench tested on actual hardware: We cycled this cell through charge, full discharge, and BMS cutoff on MagicBook 14 hardware. The protection circuit tripped correctly at low-voltage cutoff and resumed charge acceptance without manual reset.
- Post-install calibration — MagicBook battery learn cycle: After fitting, discharge the laptop to hibernate cutoff under normal use, then charge uninterrupted to 100% without waking the machine. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on this platform.
BIOS reporting poor battery health immediately after fitting a new cell
The MagicBook BIOS caches health data from the previous cell's EEPROM. When a new cell goes in, the stored cycle count and capacity figures no longer match the live readings, triggering a false poor-health flag. This is not a fault with the replacement cell. Run one full discharge-to-hibernate then a continuous charge to 100% — the learn cycle overwrites the cached data and the health indicator resets to normal.
Laptop shuts down at 20–30% battery shown on screen
This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The OS reads a percentage based on the old cell's discharge profile, so the reported figure is ahead of real voltage. Under combined CPU and display load, the cell hits its minimum voltage floor before the gauge reaches 0%, and the system cuts out. Two or three full discharge-and-charge cycles recalibrate the fuel gauge IC. After calibration, shutdown should not occur above 5% indicated charge.
