The life of a solar led outdoor lights can reach 4 or 5 years, but the battery is relatively easy to lose. In general, the battery for solar led outdoor lights is buried underground, but do you know why the solar battery is buried underground? Today, solar led outdoor lights batteries generally use gel batteries. They are large in size and heavy in weight. They cannot be installed on the lamp head or on the pole, so they can only be buried underground. Of course, not only for this reason, but also the battery buried in the ground has many benefits:

       1.Anti-theft The battery is an important part of the best outdoor solar lights, and the price is relatively expensive, so it will naturally be targeted by some lawless elements. Therefore, the battery must be buried deep underground, and can not be buried too shallow, otherwise it will provide convenience for thieves.
