About this replacement
Acer GL702VI Series — 14.8V Li-Polymer Replacement Battery (0B110-00490000)
This is a 14.8V 5800mAh (85.84Wh) lithium-polymer battery for the Acer GL702VI gaming laptop. It fits the GL702VI, GL702VI-1A, ROG STRIX GL702VI-BA012T, ROG STRIX GL702VI-BA014T, and more than a dozen additional variants in the GL702VI family. It replaces OEM part numbers 0B110-00490000, A42LM5H, and A42N1710.
- GL702VI family fit: Every GL702VI variant in this lineup runs the same 14.8V four-cell battery rail with the same connector and BMS handshake. Voltage, pin-out, and physical dimensions match across all listed SKUs — the BIOS will recognise the pack without a firmware workaround.
- Bench tested on actual hardware: We cycled this pack through charge and full-draw discharge on a GL702VI with the GTX 1080 active. The BMS held the charge curve correctly and did not trigger an early cutoff under GPU and CPU simultaneous load.
- First-cycle calibration on the GL702VI: After installing, run one full discharge down to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that commonly appears after a cell swap on this platform.
Why the GL702VI shuts down at 20–30% battery remaining
The GL702VI pairs a GTX 1080 with a high-TDP CPU, and under combined load the draw spikes sharply. An aged or uncalibrated cell hits a voltage cliff — the actual cell voltage collapses faster than the fuel gauge IC reports. The BIOS sees the rail drop below the safe threshold and triggers an emergency shutdown even though the displayed percentage still reads 20–30%. Installing a fresh cell reduces this sharply, but calibration is still needed so the fuel gauge IC maps correctly to the new cell's discharge curve.
BIOS reporting "poor battery health" or unknown Wh rating after swap
The GL702VI BIOS reads battery health data from EEPROM embedded in the pack. When a new cell is installed, the EEPROM data does not match the previous cycle history, and the BIOS flags it as degraded or displays an incorrect Wh figure. This is a data mismatch, not a faulty battery. Run one full discharge-to-hibernate then a complete uninterrupted charge to 100% — this completes the BIOS learn cycle and resolves the false warning.
