Zhengzhou conley of electronic power co., LTD., founded in 2000, professional development, production, sales of 2 v, 4 v, 6 v, 12 v four series and maintenance-free lead-acid battery, gel battery and electronic charger, etc. Products are widely used in security alarm system, fire alarm system, building intercom system, elevator emergency evacuation system, emergency lights, antenna, power sprayers, electronic said, children, cartoon gas mould, washing machine, rotary table, parking lock, flashing lights, traffic lights, dc panel, solar energy, wind energy, UPS, EPS, etc for electrical system. Now let's talk about why the batteries in the solar street lamps are buried in the ground.

　　Said to solar street lamp, I believe everyone is familiar with, whether it is a rural roads, parks, community, city streets, large and small, public places, always see the figure of solar street light, it has become the main force of modern lighting, play an important role. Solar street lamp converts natural light source into electric energy for illumination, which has the advantages of energy-saving, safety, environmental protection and durability, low maintenance cost and no pollution, and is favored by all walks of life.

　　The failure rate of solar street lamp is very low and its service life is long. However, one component of solar street lamp is always easy to wear out, that is, battery. Generally speaking, the storage battery of the solar lamp is buried in the ground, but do you know why the storage battery is buried in the ground? What's the point of being buried underground?

　　1. Anti-theft: batteries are an important part of solar street lamps, and they are also quite expensive, so they will be targeted by criminals. Therefore, the battery must be buried in the deep underground, not too shallow, in case of the thieves to provide convenience.

　　2. To prevent the battery into the water: battery is very afraid of water, said although the battery outer made waterproof measures, but in order to better waterproof effect, need to be around with cement do cover processing, to further strengthen waterproof measures. In some construction, waterproof battery box is used for waterproof.

　　3. Prevent frozen: battery is general 30 ℃ to 60 ℃ below zero can be normal use, but in a cold environment, will reduce the life of battery, very few will stop working state, so, if in the colder north to install solar street light, it is necessary to put the battery is buried in the depths of more than 2 meters, so that we can maintain a certain temperature.

　　With the continuous development of science and technology, now also gradually lithium-ion batteries used in the solar street light, its large capacity, long life, light small, easy to install, replace the lead acid and gel batteries, to extend the service life of the solar street light has played a key role.
