ASUS provides battery warranty covering the below:.To protect the battery under such use, laptop users may extend battery life through the ASUS Battery Health Charging software.ĪSUS Battery Health Charging introduction Users may leave transformers connected to laptops, cell phones, or tablets during use, making the batteries remain under high charge, which may reduce battery life. If you will not use the computer for a long time, please charge the battery once a month. Because the laptops are using the embedded battery, it will have no power if the computer had not used or recharged, and then BIOS time and settings will return to default. Overheating the battery may cause it to explode or leak, leading to risk of fire.Ħ.
Do not place your computer, cell phone, or battery pack near radiators, fireplaces, furnaces, electric heaters, or other heat-producing equipment close by heat sources over 60℃ (140☏). Over-low temperatures will impair the battery’s internal chemicals, while batteries with over-high temperatures are under risk of explosion.ĥ. Avoid storing batteries in damp environments which may give increased battery discharge rates.
The best storage conditions for batteries are ambient temperatures between 10☌ - 35☌ (50☏ - 95☏), charge maintained at 50%, and battery life extended with ASUS Battery Health Charging software.Ĥ. Laptop users may extend battery life through the ASUS Battery Health Charging software.ģ. When AC power supply is used constantly for laptops, cell phones, or tablets, the user should discharge the battery to 50% at least once every two weeks to release the battery from persisting high voltage which may reduce battery life. Recharge the battery every three months to 50% to prevent battery damage by over-discharge due to long-term storage without using.Ģ. If a laptop, cell phone, or tablet will not be used for a long time, charge the battery to 50%, turn the device off, and remove the AC power supply (adapter). Contact your local ASUS customer service to dispose of batteries ( ).ġ. When replacing swollen batteries, do not discard the old swollen battery into common domestic waste.
Swollen batteries should be replaced and discarded properly, though they do not create safety issues. After using a battery for some time, under some conditions it will have a degree of swelling. Li-ion batteries, featuring continuous chemical reactions, will naturally decline over time and lose capacity. Batteries are essentially consumables. Even though the device has been turned off and the AC adapter is removed, the system still needs slight power consumption, so it's a normal scenario when the battery level still goes down. This is part of the system’s battery protection mechanisms. When the battery temperature is too high or becomes overheated, battery charging capacity will be limited or even stop. Batteries charged or stored under high ambient temperatures may have permanently damaged capacity and accelerated battery life decline. * A battery’s charge initiation capacity (%) is usually set between 90%-99%. To extend battery life, when a battery maintains 90%-100% power after being fully charged, the system may not recharge due to battery protection mechanisms. Frequently charging a battery under high voltage will quicken its aging. When a battery-charged laptop is externally connected to additional USB or Thunderbolt devices, the battery power will also discharge faster. For example, running computation-heavy programs, such as graphics software, gaming software, and video playing, consumes more power than running general word processing software. The battery’s discharge rate depends on the laptop’s or tablet’s software operations and power management settings. High/low operating temperatures and abnormal operations may result in 60% or more rapid decrease of the battery’s life cycle within a short time. Battery life decline varies with the system design, model, system power consumption, program and operating software consumption, and power management settings. Afterwards the battery capacity will drop to 80% of its initial capacity. Under normal usage conditions and in ambient temperatures (25℃), the Li-ion battery is expected to discharge and recharge normally for 300 cycles (or about one year). The life of a Li-ion battery is approximately between 300-500 cycles.
Due to the chemical properties of Lithium ions, battery capacity decreases gradually with use over time. More ASUS Battery Information Center Last Update : 9
