About this replacement
Asus GL752JW / GL752VL Series — 15V Li-ion Replacement Battery (A41N1501)
This is a 15V, 2600mAh (39Wh) Li-ion replacement battery for the Asus GL752JW, GL752VL, GL752VL-1A, GL752VL-2B, and over 230 additional GL752 variants. It replaces OEM part numbers A41N1501, L41LK2H, L41LK9H, 0B110-00360000, 0B110-00360100, and A41Lk9H. Cross-reference your existing part number before ordering.
- GL752 platform compatibility: The GL752 line shares a common 15V four-cell battery architecture across its sub-variants. The connector pinout, BMS handshake protocol, and voltage rail are identical across the GL752JW, GL752VL, and related models — which is why one part number covers the range.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on GL752-series hardware. The BMS negotiated charge termination correctly at full capacity, and the protection circuit tripped as expected under over-discharge conditions. No false low-voltage cutoffs were observed.
- Post-install recalibration on GL752: After fitting this cell, run one full discharge until the laptop hibernates at cutoff, then charge uninterrupted to 100% without using the laptop. This gives the BIOS battery learn cycle a clean data set from the new cell and clears the inaccurate health warning that appears after every cell swap on this platform.
BIOS reporting poor battery health immediately after fitting the GL752 replacement
The GL752 BIOS reads health data stored in the old cell's EEPROM and compares it against what the new cell reports. A fresh cell has no charge history, so the BIOS flags it as unknown or degraded on first boot — this is a firmware read issue, not a fault with the replacement. Running the battery learn cycle (full discharge to hibernate cutoff, then uninterrupted charge to 100%) writes fresh calibration data. After one or two complete cycles, the BIOS health reading normalises and the warning clears.
GL752 shutting down at 20–30% charge remaining
This happens when the fuel gauge IC has not yet calibrated against the new cell's actual charge curve. The gauge estimates remaining charge using data from the old cell, so it reports 25% while the real cell voltage is already near the BMS cutoff floor. Under full CPU and display load, the voltage drops fast and the BMS trips before the gauge catches up. Run two full discharge-to-hibernate then charge-to-100% cycles — the fuel gauge IC recalibrates against the new cell and the shutdowns stop. If the problem continues beyond three cycles, check the cell voltage at shutdown with a multimeter; it should read no lower than 12.0V at the battery terminals.
