Adata XPG XENIA 15 Replacement Battery 11.4V 8000mAh

Adata XPG XENIA 15 / XENIA I7 — 11.4V Li-Polymer Replacement Battery (3ICP7/63/69-2)

This is an 11.4V, 8000mAh (91.2Wh) Li-Polymer battery for the Adata XPG XENIA 15 and XPG XENIA I7 gaming laptops. It replaces OEM part numbers 3ICP7/63/69-2 and GKIDT-00-13-3S2P-0. If your original cell has degraded or the laptop no longer holds a charge off the mains, this is the direct swap.

• XPG XENIA 15 and XENIA I7 fitment: Both models share the same 3S2P Li-Polymer pack configuration, voltage rail, and connector pinout. The BMS handshake protocol is identical across the two, so one part number covers both variants without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the XPG XENIA platform. The BMS communicated correctly with the EC, accepted a full charge without cutoff errors, and reported capacity data to the OS without triggering fault flags.
• First-cycle calibration on the XENIA: After fitting, run the battery down until the laptop hibernates, then charge uninterrupted to 100% without using the machine. This forces the BIOS battery learn cycle to reset against the new cell data and clears the inaccurate health warning that appears after every cell swap on the XPG platform.

BIOS reporting battery health as poor or unknown after replacement

The XPG XENIA BIOS reads health data from EEPROM embedded in the battery pack. When a new cell goes in, the EEPROM data does not match the charge history the BIOS expects, so it flags the battery as degraded or unknown. This is an EEPROM mismatch, not a fault with the replacement cell. Running one full discharge-to-hibernate followed by an uninterrupted charge to 100% resets the learn cycle and overwrites the stale EEPROM read. After two to three full cycles, the BIOS health indicator will update to reflect the actual cell state.

Laptop shutting down abruptly at 20–30% charge shown on screen

Under full CPU and display load, the XENIA draws sustained current that can expose a voltage cliff in a degraded or uncalibrated cell. The fuel gauge IC maps percentage to voltage curves from the old cell, so 25% displayed may actually be below the BMS cutoff threshold for the new chemistry. The laptop cuts power before the OS can write a proper hibernation state. Fix this by completing two full discharge-to-hibernate cycles — this allows the fuel gauge IC to recalibrate its voltage-to-percentage curve against the new cell, and shutdowns at false-high percentages will stop. Target a resting voltage of 11.1V at the point hibernation triggers during calibration.
