Generally speaking, the service life of lithium-ion batteries for solar street lights is about 5-8 years, and even shorter ones can reach over 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 batteries can lead to an earlier turn off time for solar street lights and a decrease in lighting time on rainy and cloudy days, which are normal phenomena. For solar street lights, the most important components are battery panels and batteries, so the lifespan of lithium-ion batteries directly affects the overall lifespan of the street lights.

When purchasing solar streetlights, it is recommended to have a reasonable configuration of lithium-ion batteries, which should not be taken lightly. The lifespan of lithium-ion batteries is determined by 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 ensures longer lighting time on rainy and cloudy days.

Daily maintenance can also affect the service life of solar street lights. In the early stages of installation, 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 immersed 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.
