As far as I am aware, NiCd (nickel cadmium) batteries have a "memory effect" where over time as you charge and discharge the battery without completely discharging/charging them, the battery will "remember" and the available amount of charge will decrease.
Li+ (Lithium ion) batteries do not suffer from memory effect, but they do have a shelf life starting from when they were manufactured; as Lithium ion batteries age, they simply do not hold as much charge. However, I'm not sure what the standard shelf life of a Li-ion battery is.
