Generally speaking, the service life of lithium-ion batteries for solar street lights is about 5-8 years, and even shorter ones can reach more than 5 years. Compared to lead-acid batteries with a service life of about 3 years, using lithium-ion batteries for solar street lights is very cost-effective. Usually, after five years of use, the decline in capacity of solar energy batteries can cause the daily turning off time of solar street lights to be earlier and the lighting time to be reduced on cloudy and rainy days, which are normal phenomena. For solar street lights, the most important components are the battery panel and battery, so the service life of lithium-ion batteries directly affects the overall service life of the street lights.

When purchasing solar street lights, it is recommended to have a reasonable configuration of lithium-ion batteries, and not to pull the cart too quickly. The lifespan of lithium-ion batteries is their cyclic discharge lifespan. Assuming that the capacity of a lithium-ion battery is only sufficient for daily discharge, the battery is easily damaged. If the capacity of a lithium-ion battery is several times the daily discharge, it means that there is a cycle in a few days, which greatly extends the service life of the lithium-ion battery and can ensure longer illumination time on cloudy and rainy days.

Daily maintenance can also affect the service life of solar street lights. In the initial installation stage, it is necessary to strictly follow the construction standards, reasonably match the configuration of lithium-ion batteries, and increase the capacity of lithium-ion batteries; Pay attention to waterproofing to prevent lithium-ion batteries from being soaked in water for a long time; Prevent lithium-ion batteries from hanging on solar street lamp poles, as high direct sunlight temperatures in summer and low temperatures in winter can shorten the service life of lithium-ion batteries for solar street lamps.
