About this replacement
Huawei MateBook X Pro 2021 — 7.64V Li-Polymer Replacement Battery (HB4593R1ECW-22A)
This is a 7.64V, 7300mAh (55.77Wh) Li-Polymer replacement battery for the Huawei MateBook X Pro 2021. It also fits the MateBook 14 KelvinL-WFH9B, MateBook 14 2020 Intel, and MateBook X Pro MACHD-WFE9. OEM part numbers covered: HB4593R1ECW-22A, HB4593R1ECW-22B, and HB4593R1ECW-22C.
- MateBook X Pro and MateBook 14 compatibility: These models share the same 7.64V two-cell Li-Polymer architecture, connector pinout, and BMS handshake protocol. All three OEM part variants use the same physical form factor and EEPROM chemistry data, so the BIOS accepts them without driver changes.
- Bench tested on actual hardware: We ran this cell through charge, discharge, and load cycles on a MateBook X Pro 2021 unit. The BMS negotiated correctly, charge termination triggered at the expected voltage ceiling, and the EC reported a valid battery status throughout.
- MateBook battery learn cycle after installation: After fitting this cell, let the laptop discharge fully until it hibernates, then charge uninterrupted to 100% without unplugging mid-cycle. This resets the BIOS battery learn cycle and clears the inaccurate health warning that commonly appears after a cell swap on MateBook hardware.
Why the MateBook X Pro shuts down at 20–30% after a battery swap
The fuel gauge IC in the MateBook X Pro calibrates its state-of-charge curve against the old cell's discharge profile. When a new cell goes in, the IC's learned voltage-to-capacity map no longer matches the new chemistry, so it misreads the remaining charge. Under full CPU and display load, the actual cell voltage drops faster than the IC predicts, triggering an emergency shutdown before the gauge reaches zero. Running two to three full discharge-to-hibernate and charge-to-100% cycles forces the IC to rebuild its curve against the new cell and resolves the early shutdown behaviour.
BIOS reporting battery Wh rating as incorrect after cell replacement
The Wh figure the BIOS displays comes from EEPROM data embedded in the battery's protection circuit, not from a live capacity measurement. If your system info shows a Wh value that does not match 55.77Wh, the EC is reading a cached value from the previous cell or from a default EEPROM register on the new one. This is a reporting artefact, not a fault with the cell itself. To refresh it, perform a full discharge to hibernate cutoff followed by an uninterrupted charge to 100%, then reboot and check the BIOS battery page again.
