Which type of wet cell is commonly used as a starter battery for diesel trucks?

The flooded battery is commonly used as a starter battery for diesel trucks due to its ability to provide high cranking power necessary for starting large engines. These batteries are designed to handle the high demands of diesel engines, especially in colder climates where more power is required to turn over the engine.

Flooded batteries, also known as wet cell batteries, have liquid electrolyte and allow for good current flow, making them ideal for high-starting applications. They are also generally more cost-effective and can be serviced easily by adding water to maintain the electrolyte levels.

In contrast, gel cell batteries and sealed lead-acid batteries, while useful in certain applications, do not provide the same level of performance and power output needed for starting heavy-duty diesel engines. Lead-acid batteries refer broadly to a type of battery that encompasses several subtypes, including both flooded and sealed variants, but the specific configuration that is most effective in this scenario is the flooded type.
