One major disadvantage of using lead-acid batteries in vehicles is their weight. Lead-acid batteries are heavy, which can impact fuel efficiency and handling. They also have a limited lifespan and require regular maintenance. Additionally, lead-acid batteries can be prone to sulfation, which can reduce their performance over time.

Lead-acid batteries have been applied in energy storage and are widely used in emergency lights, cars, navigation, aviation, military and other fields [1], [2], [3], [4] has a simple and reliable structure, low cost, high safety and good recycling, so it has an irreplaceable position and value in the field of internal combustion engine start-up, backup …
Electric cars are becoming increasingly popular as people seek more environmentally friendly travel methods. While lithium-ion batteries are often used in electric vehicles, lead-acid batteries have also been used in some models.
Therefore, the lifespan comparison is: lithium battery > graphene battery > lead-acid battery. If it is daily travel, then lead-acid battery is enough, but if you have a certain pursuit of performance, you can choose lithium battery. 4. Safety comparison of lead-acid batteries, graphene batteries, and lithium batteries
The greyed-out portion of the bar chart in Fig. 4 represents the whole cradle-to-gate process of the lead-acid batteries. Since the contribution tree for the lead-acid batteries'' cradle-to-gate phase is unavailable, a breakdown is impossible, and an aggregate value is shown. The LIB outperform the lead-acid batteries.

Lead acid batteries are cheaper - and also can be 100% recycled. They generally last 5-8 years and don''t require any safety precautions like lithium''s need. If you overcharge a lead acid battery it will just gas off electrolyte. Weight doesn''t matter all that much either, you wouldn''t notice a huge difference.
Lead-acid batteries have been around for over 150 years and are still widely used today due to their durability, reliability, and low cost.
