The most common type of battery for vehicles and heavy machinery is the lead-acid battery, but within this broad category are several specific types. The most commonly used type of lead-acid battery is the flooded, or wet-cell, battery. Other types of lead-acid batteries include the gel battery and the absorbed glass mat (AGM) battery. While gel and AGM batteries are always sealed, wet-cell batteries come in both sealed and unsealed versions. All three types of these sealed batteries have some important differences that can play a role in deciding which one to purchase.

Each battery is composed of several cells, and inside each cell are two metal plates. The positive plates are made of pure lead while the negative plates are lead oxide. These plates are submerged in a solution that is approximately 33.5% sulfuric acid. Electricity
