Asus GL553VD Replacement Battery 14.4V 2600mAh A41N1611

Asus GL553VD Series — 14.4V Li-ion Replacement Battery (A41N1611)

This is a 14.4V 2600mAh (37.44Wh) Li-ion replacement battery for the Asus GL553VD gaming laptop series. It fits the GL553VD, GL553VD-1A, GL553VD-1B, GL553VD-2B, and related variants. OEM part numbers covered include A41N1611, A41LK5H, A41LP4Q, and OB110-00470000.

• GL553VD series compatibility: All listed GL553VD variants share the same battery bay format, connector pinout, and BMS communication protocol. The 14.4V rail and four-cell Li-ion configuration are consistent across the 1A, 1B, and 2B sub-models, so one cell swap covers the full range without modification.
• Bench tested on actual hardware: We ran charge and discharge cycles on the GL553VD platform and confirmed the BMS handshake completes correctly. The protection circuit trips at the expected low-voltage cutoff, and charge termination occurs cleanly at full cell capacity without overrun.
• First-cycle conditioning on the GL553VD: After installation, 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 replacement on this platform.

BIOS reporting poor battery health immediately after replacement

The GL553VD BIOS reads health data stored in the battery's EEPROM. When a new cell goes in, the EEPROM contains factory default values that do not match the laptop's charge history, so the BIOS flags the battery as degraded or unknown. This is a data mismatch, not a fault with the cell. Run a full discharge to hibernate cutoff followed by a full uninterrupted charge to 100% — the BIOS learn cycle re-calibrates against the new cell and clears the warning.

GL553VD shutting down abruptly at 20–30% charge shown

The fuel gauge IC estimates state of charge based on learned discharge curves from the previous cell. With a new cell installed, those curves are wrong, and the gauge misreads remaining capacity under load. Under full CPU and display draw, the cell voltage drops faster than the gauge predicts, and the system hits the low-voltage trip point while the OS still shows 20–30%. Two to three full discharge-to-charge calibration cycles bring the fuel gauge IC back into alignment with the actual cell chemistry. After calibration, the cutoff should not occur above 5–8% remaining.
