Uniwill A32-H24 Laptop Replacement Battery 11.1V 4400mAh

Uniwill T410IU-T300AQ / T410TU — 11.1V Li-ion Replacement Battery (A32-H24)

This 11.1V, 4400mAh (48.84Wh) Li-ion battery replaces the original cell in the Uniwill T410IU-T300AQ and T410TU notebooks. It matches the OEM voltage rail and connector footprint, so the BIOS recognises it without adapter hardware. Use the Capacity figure above — 4400mAh — as the authoritative spec for this listing.

• T410IU-T300AQ and T410TU compatibility: Both models share the same 11.1V three-cell architecture, connector pinout, and BMS handshake protocol, which is why a single cell covers the pair. The BIOS battery management interface on each uses the same EEPROM data structure, so the replacement communicates state-of-charge correctly once calibration cycles are complete.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the T410 platform. The BMS reported charge current within spec, protection cutoffs triggered at expected low-cell voltage thresholds, and the OS fuel gauge stabilised after two full calibration cycles.
• Post-install discharge cycle on the T410 platform: After fitting this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on the T410 series.

BIOS reporting poor battery health immediately after fitting a new cell

The T410 BIOS reads health data from EEPROM registers that were written by the original cell over its service life. A new cell arrives with factory EEPROM values that do not match the degraded baseline the BIOS expects. This mismatch causes the system to flag the battery as poor or unknown before any real capacity measurement has occurred. Run two full discharge-to-hibernate and charge-to-100% cycles — the BIOS rewrites its baseline from the new cell's EEPROM data and the health warning clears.

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

This happens when the fuel gauge IC is still calibrated against the old, degraded cell's voltage curve. The new cell hits a steeper voltage drop under combined CPU and display load than the IC anticipates, so it reads 20–30% on screen when the actual cell voltage has already crossed the low-voltage cutoff threshold. It is not a fault in the replacement cell. Force a full discharge to hibernate — do not interrupt it — then charge to 100% without unplugging; the fuel gauge IC re-maps its curve against the new cell and reported percentage aligns with actual remaining capacity. After two such cycles, the shutdown-at-20% behaviour stops.
