Even rechargeable batteries wear out. After repeated use and recharging, batteries simply lose their ability to store power. Under normal use, a Lithium ion battery can keep your notebook running longer on a single charge, but they may last an average of only 400 use and recharge cycles, or about a year of normal use.
