Direct replacement for Gigabyte Aero

This 15.2 V lithium-ion battery replaces part numbers GAG-J40, 4ICP4/77/128 and 541387460002, 541387460003, 541387460005. It fits Aero 14, 15, 17 and Aorus X5, X7, X9 models listed by the supplier. The pack is supplied new in black.

94.24 Wh capacity for full-day mobility

At 94.24 Wh the cell delivers extended runtime for typical productivity, media playback and light creative workloads on compatible Aero 14, 15 and 17 chassis. Heavy GPU loads such as GTX 1050 TI or RTX 20 series discrete graphics will draw the pack down faster, so plan for a charger during sustained gaming or rendering sessions.

Black lithium-ion pack with 12-month coverage

The lithium-ion chemistry operates at 15.2 V and slots into the original battery bay without adapters or cable changes. A 12-month warranty backs the replacement. Buyers needing higher-wattage configurations or non-listed chassis should verify compatibility before ordering.

Questions about this item

Will the 15.2V 94.24Wh battery fit my Aero 14-K7 alongside the original GTX 965M graphics card?

Yes, the GAG-J40 is listed as compatible with the Aero 14 (GTX 965M) and Aero 14-K7 models, so it will work with your existing graphics card.

How can I confirm the 15.2V 94.24Wh battery is working correctly after installation?

Check that the laptop powers on without the AC adapter and that the operating system reports a charge capacity close to 94.24Wh and a voltage near 15.2V.

Does the package include screws or tools for the Aero 15-X9, or must I buy them separately?

The package includes only the battery; mounting screws and any opening tools are not supplied and must be sourced separately.
