ASUS Battery Health Charging technology
Leaving a laptop plugged in when the battery is already fully charged may degrade the battery, resulting in a shorter lifespan. It may also lead to battery swelling due to internal gas buildup caused by oxidation, potentially warping or damaging the laptop. ASUS Battery Health Charging technology allows you to set the state of charge to 60%, 80% or 100%, prolonging battery lifespan and reducing the chance of battery swelling.
