Huawei MateBook D HB46K497ECW Compatible Battery 11.4V

Huawei MateBook D Series — 11.4V Li-Polymer Replacement Battery (HB46K497ECW)

This is an 11.4V, 3700mAh (42.18Wh) lithium-polymer replacement battery for the Huawei MateBook D, MateBook D 2018, MateBook D 53010BAJ, and MRC-W00 series notebooks. It replaces the original HB46K497ECW cell when the factory battery no longer holds a usable charge. Dimensions are 221.50 x 112.80 x 4.10mm — a direct physical match for these models.

• MateBook D compatibility across revisions: The MRC-W00 and 53010BAJ share the same battery bay dimensions, connector pinout, and BMS handshake protocol, which is why one cell covers both generations. The BMS communicates charge state over the same SMBus lines across these variants.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on MateBook D hardware. The BMS accepted the cell without fault flags, charge current stepped down correctly at 95%, and the protection circuit tripped cleanly at low-voltage cutoff.
• Post-install discharge cycle on MateBook D: After fitting this cell, run one full discharge until the laptop hibernates, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in Power Manager after every cell swap.

Why the MateBook D BIOS reports poor battery health immediately after a cell swap

The MateBook D stores battery health data in EEPROM on the original cell. When a new cell goes in, the BIOS reads stale EEPROM values that don't match the new chemistry and flags the battery as degraded or unknown. This is a firmware-side calibration issue, not a fault with the replacement cell. Running one complete discharge-to-hibernate then a full uninterrupted charge gives the fuel gauge IC enough data to overwrite those stale values. After two or three cycles, the health reading in Power Manager stabilises.

This happens when the cell voltage drops below the BMS cutoff threshold under combined CPU and display load, even though the OS fuel gauge still shows charge remaining. The fuel gauge IC is reading a stored capacity curve that no longer matches the cell's actual voltage-to-capacity relationship. On a freshly installed cell, this mismatch clears after two or three full calibration cycles. If it persists beyond three cycles, check that the BIOS is not applying a charge limit — navigate to Settings, then Power, and confirm the battery protection mode is set to standard rather than limited.
