Lithium manganese battery generally has a nominal voltage above 3.0 volts, more suitable for integrated circuit power, widely used in computers, calculators, watches.
Nowadays, lithium-ion batteries are widely used in mobile phones, laptops, power tools, electric cars, street lamp backup power, navigation lights and household appliances.
Lithium battery has Higher energy.With high storage energy density, it has reached 460-600wh /kg, about 6-7 times that of lead-acid batteries.
