About this replacement
Acer G752VS Series — 14.4V Li-ion Replacement Battery (0B110-00380000)
This is a 14.4V, 5800mAh (83.52Wh) Li-ion replacement battery for the Acer G752VS gaming laptop and its variants, including the BA184T, BA185T, and BA191T. It fits the full G752VS line sharing the 0B110-00380000, 0B110-00380200, and A42N1520 part numbers. Install it when the original cell no longer holds charge or fails to register in the system.
- G752VS platform fit: Every model in the G752VS line runs the same 14.4V four-cell battery rail with identical connector pinout and BMS handshake. That shared architecture is why one cell fits all 55+ variants without firmware changes.
- Bench tested on actual hardware: We cycled this cell through full charge and discharge on a G752VS unit. The BMS communicated correctly with the EC, reported accurate state-of-charge, and held voltage under a sustained CPU plus display load without triggering a low-voltage cutoff prematurely.
- First-cycle calibration on the G752VS: After installation, run the laptop on battery until it reaches hibernate-cutoff, then charge it uninterrupted to 100%. This forces the G752VS EC to relearn the cell's capacity curve and clears the inaccurate health warning that appears after every cell swap.
Why the G752VS BIOS reports poor battery health immediately after a cell swap
The G752VS stores battery health data in EEPROM on the embedded controller. When a new cell goes in, the EC compares current readings against the stored profile from the old, degraded cell. The mismatch triggers a "poor health" or "replace battery" warning even though the new cell is fully functional. One full discharge-to-hibernate followed by an uninterrupted charge to 100% resets the learn cycle and clears the warning.
G752VS shutting down at 20–30% charge shown on the fuel gauge
This happens when the fuel gauge IC has not yet calibrated against the new cell's actual voltage curve. The displayed percentage is still mapped to the old, depleted cell's profile, so the EC hits a voltage floor the gauge doesn't show accurately and cuts power. It is not a fault with the replacement cell. Run two to three full discharge-and-charge cycles and the fuel gauge IC will recalibrate — shutdowns at false percentages stop once the reading tracks actual cell voltage, which should hold above 13.6V at the 20% mark after calibration.
