All battery have a finite life span no matter what device it powers. Rechargeable batteries are no different from normal batteries with the exception that they can be recharged a finite number of times. Under normal use rechargeable batteries have a usable life of between 3000-550 recharge cycles (depending on the modle used).

Battery Type: Li-ion
Capacity: 57Wh / 8Cell
Color: Black or Silver
Heat, Loading and Battery LifeHeat is a killer of all batteries and high temperatures cannot always be avoided. This is the case with a battery inside a laptop, a starter battery under the hood of a car and stationary batteries in a tin shelter under the hot sun. As a guideline, each 8°C (15°F) rise in temperature cuts the life of a sealed lead acid battery in half.

Batteries, given their chemical nature, are prone to wear, corrosion, leakage and outright failure due to events like short circuits and lightning strikes. Given their propensity to fail and to have decreased performance over time, it is important to be able to identify and monitor their performance. With BatteryMon, monitoring the state of your laptop battery or UPS has never been easier. BatteryMon has the following feature
A VRLA batteryfor stationary applications that would last 10 years at 25°C (77°F) would only live for five years if operated at 33°C (95°F). Once the battery is damaged by heat, the capacity cannot be restored. The life of a battery also depends on the activity and is shortened if the battery is stressed with frequent discharge.
Lithium-ion must be stored in a charged state, ideally 45 percent. This assures that the battery will not drop below 2.50V/cell with self-discharge and fall asleep.

High capacity has limited use if the battery is unable to deliver the stored energy effectively. To bring the power out, the battery needs low internal resistance. Measured in milliohms (mW), resistance is the gatekeeper of the battery; the lower the value, the less restriction the pack encounters. This is especially important with heavy loads and high current pulses, as elevated resistance causes the voltage to collapse and trigger an earlyshutdown. The device turns off and valuable energy is left behind. Figure 2 illustrates batteries with low and high internal resistance as free-flowing and restricted taps.
When long time without using laptop, Keep it in standby or sleep mode. It can both save the power and extend the ASUS G53SW battery life.
Finding the 40 percent SoC level is difficult because the open circuit voltage (OCV) of batteries does not lend itself well to state-of-charge estimations. For lack of better methods, voltage is nevertheless used as a rough fuel gauge indicator. The SoC of Li-ion is roughly 50 percent at 3.80V/cell and 40 percent at 3.75V/cell. Allow Li-ion to rest 90 minutes after charge or discharge before taking the voltage reading to get equilibrium.
