Lead-acid batteries and lithium batteries have essential differences in principle, performance and applicable scenarios.

1. Energy density and weight: The core advantage of lithium batteries is their extremely high energy density. Under the same amount of electricity, their volume and weight are only about one-third of those of lead-acid batteries, making them very lightweight and suitable for applications that are sensitive to weight and space (such as drones and high-end electric vehicles). Lead-acid batteries are very bulky.

2. Lifespan and cycle life: Lithium batteries have a longer lifespan and can typically be fully charged and discharged over 1,500 times. Lead-acid batteries have a relatively short lifespan, and their capacity usually drops significantly after 300 to 500 deep cycles.

3. Efficiency and charging speed: Lithium batteries have a high charging efficiency (up to over 95%), a high energy conversion rate, and support fast charging. Lead-acid batteries have a relatively low charging efficiency (about 70-85%) and a slow charging speed.

4. Environmental Protection and Cost: The main advantages of lead-acid batteries lie in their mature technology and low cost. However, the lead and sulfuric acid inside them are heavy metals and strong acids. If not recycled properly, they can cause serious pollution. Lithium batteries do not contain heavy metals and are more environmentally friendly, but their manufacturing costs are high.

5. Memory Effect and Maintenance: Lithium batteries have no memory effect and can be charged at any time. Traditional lead-acid batteries require regular maintenance (adding distilled water) and have a tendency to have a memory effect.

Summary: Lead-acid batteries dominate markets such as car starting, low-speed electric vehicles, and backup power supplies due to their low cost and high reliability. Lithium batteries, with their high performance, long lifespan and lightweight, have become the mainstream choice for high-end electric vehicles, digital products and energy storage systems. The choice depends on a trade-off between budget, performance and weight.
