Solar street lights are a sustainable and eco-friendly solution to providing illumination in outdoor areas. They are designed to harness energy from the sun during the day and use it to power LED lights at night. However, one of the questions that many people ask is: do solar street lights have a battery? The answer to this question is yes.

The battery used in solar street lights is typically a deep-cycle battery. This type of battery is designed to discharge a large amount of its stored energy over an extended period. Deep-cycle batteries are also able to withstand frequent charge and discharge cycles, making them ideal for solar applications where charging and discharging occur daily.

In conclusion, solar street lights do have a battery that is a significant component of the system. The battery stores the energy generated by the solar panel during the day, which is used to power the LED lights at night. A deep-cycle battery is typically used, and it is connected to the solar panel through a charge controller. The size of the battery required depends on the location and the amount of illumination required.
