BU-201b: Gel Lead Acid Battery

The early gelled lead acid battery developed in the 1950s by Sonnenschein (Germany) became popular in the 1970s. Mixing sulfuric acid with a silica-gelling agent converts liquid electrolyte into a semi-stiff paste to make the gel maintenance free.

What are the Different Types of Lead-Acid Batteries?

The most common type of lead-acid battery is the flooded battery, also known as a wet-cell battery. These batteries have a liquid electrolyte that is free to move around the battery cells. Another type of lead-acid battery is the sealed battery, which is also known as a valve-regulated lead-acid (VRLA) battery.

Past, present, and future of lead–acid batteries
