Batteries are portable energy supplies, which are capable of producing electric current from a chemical substance called an electrolyte. Cars are best to use dry battery, as battery fail problem in cars can only be solved through battery boost and service company. Whereas wet cell batteries get their power from a liquid electrolyte, dry cell batteries generate power from a slightly moist paste. Battery manufacturers classify battery types as either primary (single-use disposables) or secondary (rechargeable).
Key Difference: The primary difference between wet cell and dry cell battery is that the wet cell battery uses a liquid electrolyte, whereas a dry cell uses a paste electrolyte. The electrolyte is what allows the battery to transfer a charge between nodes. Due to the usage of a liquid electrolyte, the wet cell battery must be used in a specific orientation, i.e. the right side up, using the battery in any other way will result in the fall out of the liquid electrolyte. The dry cell does not have this problem and can typically be used in any direction.
Comparison between Wet & Dry Cell Batteries:
Wet Cell Batteries
- Wet Cell Batteries are usually larger in capacity and carry a larger charge. Hence, they are commonly used for larger items such as in automobiles, aviation, electric utilities, Cell phone towers and for energy storage.
- Wet cell batteries are typically larger in size they cannot easily be moved around. Some of the larger batteries may be even more difficult to move
- Challenge of moving the wet cell battery is that the liquid electrolyte might fall out and the electrolytes are typically a highly corrosive liquid substance such as sulfuric acid which will cause damage to anything it comes into contact with. Hence, one has to be extra careful while transporting or moving a wet cell battery
- A well cell battery generates power from a pair of electrodes and a liquid electrolyte solution. Early wet batteries consisted of solution-filled glass jars and with electrodes dropped into each one
- Wet cell batteries are typically used as rechargeable secondary batteries. This makes them ideal for use in motor vehicles, where the car’s alternator recharges the battery after starting
- If properly maintained, wet cell batteries also have a high number of charge-discharge cycles. They are also less likely than other batteries to suffer damage from overcharging.
Dry Cell Batteries
- Dry Cell Batteries are usually smaller and carry a lesser charge. Hence, they are typically used for smaller devices such as clocks, toys, cell phone, laptops, and other such portable devices.
- The dry cell battery is typically smaller in size and can be moved around easily. Hence, it can be said that the dry cell batteries have a more range of motion than wet cell batteries. It is also because of this that devices that use dry cell battery are often portable, whereas those using wet cell batteries usually aren’t.
- The dry cell batteries are more common and popular today than the wet cell batteries. They are surely and quickly replacing wet cell batteries are they provide certain benefits over the wet cell batteries, such as they are safer and easier to use, while also being highly portable
- Dry cells are typically used as primary cells and these batteries can handle long periods of storage because they lose their charge more slowly than secondary batteries
- Lithium ion batteries represent a type of dry cell battery well-suited for use in cell phones, due to its high energy density or its power stored versus weight. This means a small compact, durable battery can deliver a large amount of power
