Wind-solar hybrid LED street lights generally use valve-regulated sealed lead-acid battery, generally 12V and 24V. In small systems, these two types can also use nickel-hydrogen batteries, nickel-cadmium batteries or lithium batteries. Its function is to store the electric energy generated by solar cells and wind generators when there is light and wind, and then release it when needed.
The use of cost-effective gel valve-controlled sealed lead-acid batteries can be buried in the ground, which can greatly extend the life of the battery.
The self-discharge rate of gel valve-regulated sealed lead-acid batteries is low. At 25 ℃ room temperature, stand for 28 days, the self-discharge rate is less than 1.8%. Its use temperature range is wide, and it can be used in the temperature range of -40~+60℃.
The battery uses a unique alloy formula and lead paste formula, which still has excellent discharge performance at low temperatures, has strong corrosion resistance at high temperatures, and has good sealing performance, which can ensure the safety and tightness of the battery during its service life, without pollution.
The valve-regulated sealed lead-acid battery can regenerate the generated gas into water, and it does not require water replenishment and maintenance during use. The silver-plated copper terminal is used, which has excellent conductivity, and the valve-controlled sealed lead-acid battery can discharge at a large current. Strong charging acceptance, fast charging, time saving and power saving for capacity restoration, and high reliability. It has a safe and reliable explosion-proof exhaust system, which can eliminate the bulging of the battery shell due to excessive pressure when the battery is used abnormally.
