Modern ASUS laptops primarily utilize lithium-ion (Li-ion) or lithium-polymer (Li-Po) batteries. These batteries are known for their high energy density, lightweight design, and relatively long lifespan compared to older battery technologies. Lithium-ion batteries don’t suffer from the “memory effect” that plagued older nickel-cadmium batteries, meaning you don’t need to fully discharge them before recharging.
These battery types are controlled by sophisticated power management systems. These systems regulate the flow of electricity to and from the battery, preventing overcharging, overheating, and deep discharging. The power adapter supplies power to the laptop’s components, and any excess power is used to charge the battery. Once the battery reaches 100%, the power adapter typically bypasses the battery and directly powers the laptop.
Battery Charging Cycles
A battery charging cycle refers to one complete discharge and recharge of the battery. Battery lifespan is often measured in the number of charging cycles it can endure before its capacity significantly degrades. Exposing your battery to extreme temperatures, either hot or cold, can also shorten its lifespan.
ASUS Battery Health Charging Feature
ASUS laptops often come equipped with a feature called “Battery Health Charging.” This feature allows you to customize how the battery is charged, offering different modes designed to extend battery lifespan. For example, a “Maximum Lifespan Mode” might limit the battery charge to 60% or 80% to reduce the stress on the battery. The “Balanced Mode” usually charges the battery to 80%, while the “Full Capacity Mode” charges to 100%. The ideal mode depends on your usage habits. If you primarily use your laptop plugged in, limiting the charge to 60% or 80% can significantly prolong the battery’s overall health.
