They are one of the most widely used battery types because they offer great advantages over other models of solar batteries. It is a device made up of several cells capable of storing electrical energy for later use.
They consist of a gelled electrolyte (hence its name) so there can never be any kind of spill if the battery is accidentally tipped over. Thanks to this, they can be placed in any position and orientation, which is practical for installations where there is limited space to place the solar batteries. They come in a sealed container that does not require maintenance since the gas inside it recombines, avoiding the loss of water.
