Haier S530 Laptop Compatible Battery 14.4V 2200mAh

Haier S530 Series — 14.4V Li-ion Replacement Battery

This 14.4V, 2200mAh (31.68Wh) lithium-ion battery replaces the original cell in the Haier S530 and related notebook models. It fits the S500-I54200G40T01NDTS, S510, S520-N2940G40500RDTW, and additional S-series variants that share the same connector and voltage rail. Use product data capacity figures — 2200mAh — as the authoritative spec for this cell.

• S-series notebook compatibility: These models share a common 14.4V four-cell Li-ion architecture, the same physical connector, and a BMS handshake that the host BIOS reads during POST. That shared platform is why a single cell works across the S500, S510, S520, and S530 variants.
• Bench tested on actual hardware: We ran charge and discharge cycles on this cell and confirmed the BMS communicates state-of-charge correctly to the system. Charge acceptance was consistent across cycles, and the protection circuit triggered at the expected cutoff voltage under load.
• Post-install calibration cycle: After fitting this cell, run the laptop down to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the false health warning that appears after most cell swaps on this platform.

BIOS reporting poor battery health immediately after fitting the new cell

The Haier S530 BIOS reads EEPROM data embedded in the old battery and caches it. When a new cell goes in, the firmware compares live readings against stale stored values and flags a mismatch as poor health. This is not a fault in the replacement cell. Run one full discharge-to-hibernate then a full uninterrupted charge to 100% — the BIOS learn cycle overwrites the cached EEPROM data and the health warning clears.

Laptop shuts down at 20–30% charge shown on screen

This happens because the fuel gauge IC is still calibrated to the old, degraded cell. The percentage shown is based on voltage curves from that worn cell, not the new one. Under full CPU plus display load, the new cell hits a voltage point the IC misreads as near-empty, triggering shutdown early. Complete two to three full discharge and charge cycles — the fuel gauge IC re-maps its curve to the new cell and the cutoff point corrects to below 5%.
