In supporting wind-solar energy storage systems, 2V100Ah lead-acid batteries serve as both daily energy storage units and emergency standby power supplies to improve power supply reliability. Wind-solar power systems may shut down due to weather and environmental factors, and the batteries switch operating modes quickly to supplement power seamlessly and ensure continuous operation of load equipment. Adopting colloid and AGM dual technologies, they have long cycle life and stable charge-discharge performance, meeting the high-frequency working demands of energy storage systems. With the advantages of high reliability, low cost and easy maintenance, they are widely used in civil and industrial wind-solar energy storage fields with broad market promotion prospects.
