SCIENCE: Dry cell vs wet cell batteries

Did you know there are two kinds of batteries, and they are both powered in very different ways? These different kinds of batteries are called wet cell batteries and dry cell batteries. The main difference between these batteries is that dry cell batteries get their power from an electrolyte paste, whereas wet cell batteries get their power from a liquid electrolyte.

What are electrolytes?
Electrolytes are substances that have the ability to conduct and generate energy and power, so they're used in batteries. They're also found in the human bodies, animal bodies, and atoms.

Although both really good at their job, wet and dry cell batteries are used for different things. Wet cell batteries obviously contain liquid, so they usually stick to powering things that remain upright such as buses, airplanes, cars, motorcycles, and those sorts of things.
Whereas dry cell batteries are a bit more versatile and can be flipped and moved around easily. That's why we find dry cell batteries in things such as mobile phones. Furthermore, dry cell batteries can last for around 5 years, unlike wet cell batteries which don't exceed a life of over around 2 years.
