What type of battery is used in a Solar Light? How often does the battery need to be replaced?
Solar Light utilizes AA/AAA, NiCad (Nickel Cadmium) rechargeable battery or NiMh battery. These 1.2V rechargeable batteries are available at most of home centers and electronic stores. The rechargeable batteries are designed to have a life expectancy of about sixteen to thirty-two months (like mobile phone battery) under normal condition, and their output power would diminish gradually though. If the brightness of the Solar Light after a sufficient sun exposure is still fading, or the duration of lighting becomes much shorter than usual, then there is a need to replace the battery. To be reminded, the battery replaced has to be a rechargeable one rather than a non-rechargeable.
