Throughout the day, the sun replenishes the rechargeable batteries housed within the solar panels. As dusk falls, the stored electricity from these batteries illuminates the lamp. In the morning, the lights are automatically deactivated and subsequently recharged in preparation for another night of use. The solar spotlight operates fully autonomously, eliminating the need for manual activation each evening; however, manual operation is available should you prefer it. While it may be necessary to replace the battery approximately once a year, it's worth noting that some batteries can indeed last several years under optimal conditions. By properly maintaining your solar spotlight, you can ensure their longevity.
