China Factory Storage Battery 12V 300ah Battery for Solar/UPS/Power Battery

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 are not technologically advanced, their stability and reliability are unparalleled. Compared with some new battery technologies, lead-acid batteries have lower maintenance costs and higher safety. Meanwhile, due to its mature manufacturing and abundant raw material sources, the price of lead-acid batteries is relatively low, making it the preferred energy storage solution in many applications.

The working principle of lead-acid batteries is based on the chemical reaction of lead and lead oxide in sulfuric acid electrolyte. During the charging process, lead and lead oxide are respectively converted into lead sulfate, while releasing electrical energy. During the discharge process, lead sulfate is converted into lead and lead oxide, thereby consuming electrical energy. This process is reversible, so lead-acid batteries can be repeatedly charged and discharged, thereby achieving energy storage and release.

Lead acid batteries, an energy storage device widely used in various application scenarios, have been widely recognized by global users due to their reliable, stable, and cost-effective characteristics. Lead acid batteries play a crucial role in automotive starting systems, backup power sources, and even large-scale power systems.
