That strikes me to write something about the commonly misunderstandings of laptop battery. Last time we mentioned three points. Today we are going to continue this topic, just take this 42T4504 Laptop Battery for example.

If you use the battery too often, then you should discharge to about 10 ~ 15%, and then recharge. But if the battery can not boot, the lithium battery will have damaged by the discharge. So generally it should be done once every 2 months. For those who use battery too frequently, take this as long as once every 3 months.

As this 42T4504 Laptop Battery, my friend has it at home for entertainment use. So he can discharge once half a year.

As the capacity demonstrated increases or decreases is the state of the battery itself. Its not determined by your calibration.
