A wet battery is a type of battery that uses a liquid electrolyte as a conductor between its electrodes. There are a variety of synonyms for the term "wet battery." Some common alternatives include flooded battery, vented battery, cell battery, lead-acid battery, and acid battery. These batteries are commonly used in vehicles such as cars, trucks, and boats, as well as in generators, uninterruptible power supply systems, and solar power systems. Additionally, they are widely used in the industrial sector, particularly in applications such as backup power for telephone, sump pumps, and lighting systems. Whatever the name, wet batteries remain an essential component in many modern technologies.
