Laptop lithium battery tips

e batteries to use up the battery power before giving them a full charge. Because the li-ion battery used by laptop has its own laziness and would lose its activeness when being idle for long time.

It is also suggested to shut down the laptop so that battery can be fully charged. Do not remove the AC power during charge. In addition, the power of battery can easily be used up and most laptops have only one battery. For this reason, some manufacturers have developed a fast charge feature that enables the battery to replenish its power at the fastest pace after power draining up. One hour charge can give the battery back over 90% of its power. Why is not 100%? Because frequent fast 100% charge will greatly shorten the battery life. In order to prolong battery life, fast charge will have to be switched to slow charge(namely Constant Voltage charging method) when battery reaches 90% charge.

5) Don't use battery if it is not necessary because every charge/discharge time may shorten batt
