Wet cell facts for kids
A wet cell is a type of battery that uses a liquid called an electrolyte. Most batteries you use every day, like those in remote controls, have a paste-like electrolyte. But wet cells, like the ones in cars, contain a liquid.
These batteries were among the first types ever made. Even though the liquid electrolyte can spill, people still use wet cells when they need a lot of power, such as to start a car engine.

What is a Wet Cell Battery?
A wet cell is a battery that has a liquid inside it. This liquid is called an electrolyte. The electrolyte helps electricity flow through the battery. Think of it like a special juice that makes the battery work!
Most batteries you see, like the ones for your TV remote or toys, are called dry cells. They use a paste instead of a liquid. Wet cells are different because their electrolyte is a liquid.
Why Do Cars Use Wet Cells?
Cars need a lot of power to start their engines. Wet cells are great at providing this strong burst of energy. This is why you'll find a wet cell battery under the hood of most cars.
A Look Back at Wet Cells
Many of the very first batteries ever invented were wet cells. Over time, people developed dry cells, which are more convenient because they don't spill. However, wet cells are still important for jobs that need a lot of power.
Keeping Wet Cells Safe
Because wet cells have a liquid inside, there's a chance the liquid could spill. This is why they need to be handled carefully. Modern wet cells are designed to be much safer and less likely to leak than older ones.
