If the battery in Lithium mines Ontario your computer is a nickel metal hydride or a nickel cadmium then it will experience memory degradation over time. To lessen the effects of this, make sure that you run the battery down to empty every time. Also ensure that you fully recharge the battery every time you recharge it.
