GEL Sealed Lead-Acid Battery

Gel batteries are composed of lead plates and a gelified sulfuric acid electrolyte. The gel is formed by the addition of silica to the electrolyte, thus forming a semi-solid substance that holds the acid in place. Unlike normal flooded lead-acid batteries, the gel technology immobilizes the sulfuric acid electrolyte. Hence spilling or maintenance is not required. The construction is sealed, meaning that it is safe while allowing battery operation in any direction without spills of acids.
