Solar energy storage battery with 12V 200AH

Lead-acid batteries have plates of lead and lead oxides, and electrolytes of sulfuric acid in water. The main advantages of lead-acid battery are relatively stable voltage and relatively cheap price. The disadvantage is that the specific energy is relatively low, so the volume is much larger than ordinary batteries. The service life of lead-acid batteries is relatively short, generally 300-500 times of deep cycle, and the maintenance is more frequent, but because of the price advantage, it is still widely used in the solar street lamp industry.

2.Intergrated Intelligent LED Power Supply,LED street lights,LED tunnel lights,LED Floodlights,LED Highbay lights,LED Commerical,
Home lightings rtc.Meanwhile,we optimize the combination of solar energy and LED lighting perfectly.
Over the last few years' practice,it proves that solar street lights manufactured by Coursertech has been able to reach 365days normal
lighting out of climate impact,light decline rate of LED lightings controlled within 8% after using 30000hours,conversion efficiency reach
more than 92%,power factor reach 0.97.LED street light refector designed by Coursertech,could increase efficiency 30% higher,has got national
invention patent!
