Lead-acid batteries are widely used in emergency lighting equipment, vehicle starting, electric vehicles and other fields because of their large electromotive force, wide working temperature, simple structure, mature technology and reliable performance. However, this does not mean that lithium batteries are inferior. In this paper, lithium battery and lead-acid battery will be compared to help readers understand the advantages and disadvantages of the two batteries, so as to choose the appropriate battery according to specific needs and application scenarios.

High energy density

Lithium batteries have high energy density, light weight and small volume. It also has a high voltage, and the working voltage of a single lithium-ion battery is equivalent to three nickel-cadmium or nickel-hydrogen batteries connected in series, which provides powerful power for the equipment.

Environmental protection and pollution-free

Lithium batteries are environmentally friendly and pollution-free, and do not contain harmful metal substances such as cadmium, lead and mercury. Moreover, it does not contain metallic lithium, so it is not restricted by the air transport regulations prohibiting the carrying of lithium batteries.

Long charge and discharge time

Lithium batteries can be charged and discharged more than 500 times, which means a longer life. And it has no memory effect, that is to say, it can get the best performance every time it is charged.

Mature technology

Lead-acid batteries have mature technology and reliable performance, and are widely used in emergency lighting equipment, vehicle starting, electric vehicles and other fields.

Fast charging speed

With the right charger, the lithium battery can be fully charged in one or two hours, making your equipment ready at any time.
