Solar street lamps: Battery

Lead-acid battery, lithium battery and lithium iron phosphate battery are recognized as three kinds of batteries that can be used for integrated solar street lamps. Lead-acid batteries can be reused 300 to 500 times and have a lifespan of two years. Lithium battery can be charged more than 1200 times, the service life of 5-8 years, lithium iron phosphate battery can be charged more than 2000 times, the service life of more than 8 years. Therefore, it is also important to know the type of battery used in solar integrated street lamps when choosing lamps. Price is not the only consideration when choosing an integrated solar street lamp. Lithium iron phosphate battery is small in size, long in life, and has good environmental protection value. Although expensive, it has been the first choice for integrated solar street lamp batteries. Lead-acid batteries are the least recommended because they pollute the environment, and lithium iron phosphate batteries have the highest energy density per unit.
