Lead acid batteries still play an irreplaceable role in many fields. With the advancement of technology, the performance of lead-acid batteries is also constantly improving. The design of some new lead-acid batteries has begun to attempt to address the issues of energy density and lifespan, in order to further improve their performance while maintaining their stability and reliability.

Although lead-acid batteries may not be as advanced in technology as some emerging energy storage technologies, such as lithium-ion batteries, they still have many significant advantages. Firstly, the manufacturing cost of lead-acid batteries is relatively low, which makes them the preferred energy storage solution in many application areas, especially those that are cost sensitive. Secondly, lead-acid batteries have good safety performance and are less prone to safety accidents such as thermal runaway or explosion. In addition, lead-acid batteries have stable charging and discharging efficiency and can operate over a wide temperature range, enabling them to perform well under various environmental conditions.
