Explanation:

Advantages of lithium-ion batteries over lead acid batteries Weight: Lithium-ion batteries are one-third the weight of lead acid batteries. Efficiency: Lithium-ion batteries are nearly 100% efficient in both charge and discharge while the lead batteries have the 70% efficiency. Discharge: Lithium-ion batteries are discharged 100% versus less than 80% for lead acid. Cycle Life: Rechargeable lithium-ion batteries cycle 5000 times or more compared to just 400-500 cycles in lead acid. Voltage: Lithium-ion batteries maintain their voltage throughout the entire discharge cycle. Lead acid voltage drops consistently throughout the discharge cycle. Cost: Despite the higher upfront cost of lithium-ion batteries, the true cost of ownership is far less than lead acid when considering life span and performance.
