1, has a higher energy than the weight, volume energy ratio; 
 2, high voltage, single-cell lithium battery voltage is 3.6V, equal to three nickel-cadmium or nickel metal hydride rechargeable batteries in series voltage; 
 3, the self-discharge Hsiao Ke long term storage, this is the most prominent advantages of the battery; 
 4, no memory effect. Lithium does not exist the so-called nickel-cadmium battery memory effect, so no need to discharge before charging, lithium batteries; 
 5, long life. Normal working conditions, the lithium battery charge / discharge cycles greater than 500; 
 6, can be quickly charged. Lithium batteries can usually 0.5 to 1 times the capacity of the current charge, the charge time reduced to 1 to 2 hours; 
 7, can be freely used in parallel; 
 8, the battery does not contain cadmium, lead, mercury and other heavy metals, environmental pollution, is the most advanced green battery; 
 9, the high cost. Compared to other rechargeable batteries, lithium batteries expensive
