100Ah Lead Acid Battery 12V Zero Maintenance

A 1998 report released by the Advanced Lead-Acid Battery Consortium stated that through research and improvements, the specific energy of valve-regulated lead-acid batteries could be doubled, their lifespan potentially increased tenfold, and their charging time shortened by an order of magnitude. Currently, the Advanced Lead-Acid Battery Consortium is actively supporting research and improvement efforts by all relevant parties. During my country's Eighth Five-Year Plan period, the State Science and Technology Commission and the State Planning Commission designated the research and development of lead-acid power batteries for electric vehicles as a key project and provided support. my country's research and development goals for sealed lead-acid power batteries for electric vehicles are divided into two phases. The first phase requires a nominal voltage of 12V, a nominal capacity of 150Ah, a water loss (g/Ah) ≤5, a high-rate discharge capability ≥2C, a cycle life ≥750 cycles (75% DOD), and a specific energy of 30-40Wh/kg. During this first phase, overall battery performance is required to be improved. In the second period, the battery's cycle life (at 80% DOD) is required to reach 600 to 800 times, and the specific energy is required to be appropriately increased by about 40-50Wh/kg.
