What are the advantages of a lead-acid accumulator over a dry leclanche cell?

A lead-acid accumulator, such as a car battery, has a higher energy density and can store more energy per unit weight compared to a dry Leclanché cell. Lead-acid accumulators also have a longer lifespan and can withstand deep discharges without significant damage, making them more durable for repeated use. Additionally, lead-acid accumulators are more cost-effective and have a lower self-discharge rate compared to dry Leclanché cells.
