Lithium batteries provide better performance, last longer, and feature the highest energy density. 

Additionally, they require minimal maintenance, maintain their charge during long periods of storage and are lighter than traditional Lead/Acid Battery.  They also provide up to 3x the power of Lead/Acid Batteries, have more usable power available (which means smaller battery banks) and recharge faster with the same sized charger.
