Well, Laptops with NiCad (Nickel / Cadmium) batteries were suffered and more prone to Memory Effect (i.e. if a battery is repeatedly only partially discharged before recharging, the battery "forgets" that it has the capacity to further discharge all the way down.) Now-a-days, NiCad batteries were become obsolete and Li-Ion (Lithium / Ion) battery is used in most laptop computers. Li-Ion batteries perform well and are reasonably priced. Moreover, Li-Ion batteries do not suffer from the memory effect, which means that it is not necessary to run the battery dry before recharging it. Anyways for Li-Ion batteries too, it's suggested to fully cycle (fully charge and then fully discharge) the battery at least once every two to three weeks to avoid the dreaded "memory effect" and for optimum battery performance. Batteries can be discharged by unplugging the device's AC adapter and letting the device run on the battery until it ceases to function. This will insure your battery remains healthy.
