ASUS Battery Information Center
The battery pack's service life will depend on the environment temperature, humidity, and notebook PC usage.
- Battery charge capacity tends to decrease over time and use.
- Lithium-ion batteries typically have a lifespan of between 300 to 500 charge cycles. They are expected to retain around 80% of their original battery capacity after 300 charge cycles, or after about one year of use.
- High or low ambient temperatures may negatively affect battery performance, resulting in a loss of up to 70% of charge capacity.
- Other factors that may affect battery service life include system design, model type, and operating system power management settings.
- Apps can affect battery life as well: Processor-intensive apps for photo editing, gaming of video playback consumer more power than general desktop applications
|1. Batteries will lose charge over time, even if not in use. It is always best to disconnect the power adapter from a notebook if you will not be using it for more than two weeks
||2. The battery should be stored at a temperature between 10° to 30° C. Under these conditions, a typical notebook battery will have a lifespan of between 300 to 500 charge cycles.
|3. There is no need to fully discharge a battery prior to charging. A full charge cycle is when you fully use all of the battery’s charge. For example: If you use 60% of the battery charge on Monday and the remaining 40% on Tuesday, you completed one full charge cycle. The charge capacity of a battery decreases after numerous charge cycles. ASUS batteries are designed to hold at least 80% of their original charge, even after hundreds of charge cycles.
||4. Do not store the battery pack in a damp or cold environment! Moisture or a cold environment might speed up the discharge rate. The chemical ingredients inside the battery might degrade when exposed to low temperatures. On the other hand, there's risk of explosion when exposed to extremely high temperatures.
|5. To ensure optimum battery lifespan, the battery charge should be between 40 to 60%. If the battery charge falls below 20%, the notebook should be plugged in immediately to prevent possible damage to the battery.
||6. Do not place the notebook or battery near a radiator, fireplace, stove or any heat source.
Useful tips for how to extend battery charge
- Dim the brightness of your display.
- Reduce CPU performance to lower its power consumption.
- Shut down the device when not in use.
- Enable auto power-save settings.
- Turn off wireless features such as the wireless network adapter, Bluetooth or 3G cards to reduce power consumption when you’re working on tasks that don’t require network access. Closing apps and disconnecting accessories is a good idea, too.
- Terms and Conditions: ASUS battery warranty
- If a battery is within the warranty period (one year from the purchase date) and it causes the system to suddenly switch ON/OFF, shut down, or not power up, ASUS will replace the defective battery with a new one
- ASUS will replace a new battery under the following conditions: (a) The battery does not charge; (b) The notebook is not able to detect the battery; (c) The system repeatedly prompts or warns the user to replace the battery; (d) Battery Charge Indicator blinks abnormally.
- Exclusions from the Limited Warranty Service
- Normal drop in battery capacity over time due to usage.
- The product has been tampered, repaired, and/or modified by non- authorized personnel.
- Failure to provide laptop proof of purchase or the warranty seal of the laptop has been broken or altered. To avail of the limited warranty, please keep your proof of purchase and do not remove the warranty seal on the product.
- Electronic components display rust or signs of oxidation due to exposure to moisture or internal leakage.
- The laptop shows signs of damage due to misuse or negligence.
- Lithium-Ion batteries
Lithium-ion batteries are used in mobile phones and laptops and feature lithium or lithium alloy anode and a non-aqueous electrolyte solution. They provide a high voltage, a long life cycle, and a rapid charge rate. They are lightweight, non-polluting, and do not suffer the memory effect of an incomplete discharge. They can be recharged quickly and used with a smart battery charger while still maintaining a high- density power capacity.
- The lithium polymer battery
Lithium polymer batteries are the most commonly used batteries in mobile phones, tablets and laptops. They feature a higher energy density – providing up to twice the power capacity of a lithium-ion battery of the same size. They are also lightweight may be as thin as 0.5mm.
The exclusive SuperBatt technology uses the ASUS Smart Charging Algorithm to extend notebook battery potency. While standard batteries deteriorate with time and recharge to lower levels the more cycles they endure, SuperBatt enables up to 70% charge-up even after 1000 cycles – three times more than normal-cell batteries.
