LITHIUM ION BATTERY

Perfect Choice to Replace Lead Acid Battery

Lithium-ion battery is by far the battery of choice today. Advancements in lithium-ion battery technology make them affordable, light-weight and able to meet the punishing power needs of today's hi-tech, ranging fro electric power trains in auto and marine vehicles to alternative energy sotrage requirements of solar and wind power generation. With advancing demands in the electric automobile and marine vehicles markest, military defense needs, consumer elecronics, lithium ion battery is expected to significantly and rapidly expand over the next decade, there is no other battery that threatens the dominance of lithium technology.
