The main difference between lead carbon batterie and lead-acid batterie lies in the difference in electrode materials. Lead carbon batteries add carbon materials to the positive electrode, which can improve the battery's cycle life, charging and discharging performance, and sulfur resistance, while lead-acid batteries do not include carbon materials. It is composed of lead negative electrode, lead oxide positive electrode, and sulfuric acid electrolyte, with mature technology and wide application fields, but its cycle life and sulfur resistance are relatively weak.

There are the following differences in application scenarios and prices:

1. Cycle life and charge discharge performance: Lead carbon batteries have better charge discharge performance and cycle life, suitable for scenarios with high cycle life requirements.

2. Sulfur resistance: The addition of carbon materials to lead carbon batteries can improve their sulfur resistance, making them suitable for application scenarios affected by sulfides.

3. Price: Due to the improvement of lead carbon batteries, their prices are usually slightly higher than traditional lead-acid batteries. But with the development of technology and the increase in production, the price of lead carbon batteries may gradually decrease.

Based on specific application requirements and budget, the choice between lead carbon batteries or lead-acid batteries depends on:

1. If there are high requirements for cycle life and charging and discharging performance, or for scenarios that require strong sulfur resistance, lead carbon batteries can be considered.

2. If the cost budget is tight or the requirement for cycle life is not high, traditional lead-acid batteries are also a reliable choice.
