Li - Ion or Lithium Ion

Lithium cell phone batteries are more efficient and lighter in weight than other batteries listed here. Though more expensive, they develop no memory effect, and are the least toxic of current cell phone battery technologies. Charging requires a constant voltage, but the life of a Lithium Ion battery can be reduced by over 50 percent if overcharged. Use only chargers that are recommended or designed for Li - Ion batteries. Chargers made only for the nickel - based batteries should never be used to charge lithium batteries, because the levels of monitored voltage sent to the cell phone battery is different.
