Estry Standard Battery for Gateway Aero 14 K7 GAG-J40 6100mAh 15.2V

Compatible replacement for Gateway Aero 14 K7

This Estry battery replaces the original pack in Gateway Aero 14 K7 laptops. It matches the factory voltage of 15.2V and fits the same chassis footprint. The lithium cell assembly is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards. Buyers who need a different form factor or voltage should look elsewhere.

Protection circuitry and certified build

Integrated safeguards prevent overcharge, over-discharge, over-voltage and short-circuit conditions. These circuits extend usable cycle life and reduce the risk of damage to the notebook's power system. The pack carries RoHS, CE, ISO9001, UN38.3 and MSDS certifications. Users who require hot-swap capability or external charging docks will not find those features here.

Capacity choice decides runtime

The replacement delivers 6100mAh and 92.72Wh, which is higher than the 5000mAh reference capacity listed for the original part. This increase translates directly into longer unplugged operation between charges. Buyers who prioritise minimum weight over maximum runtime may prefer a lower-capacity alternative.
