Lithium Battery Advantages

 Wide variety of shapes and sizes efficiently fitting the devices they power.Much lighter than other energy-equivalent batteries (75% lighter than lead-acid battery)High open circuit voltage in comparison to aqueous batteries (such as lead acid, nickel-metal hydride and nickel-cadmium).This is beneficial because it increases the amount of power that can be transferred at a lower current.No memory effect.(you can charge the battery whenever you want)Self-discharge is very small, the rate of approximately 5-10% per month.  (compared to over 30% per month in common nickel metal hydride batteries, approximately 1.25% per month for Low Self-Discharge NiMH batteries and 10% per month in nickel-cadmium batteries). Components are environmentally safe as there is no free lithium metal.
