Wet cell



A wet cell is a galvanic secondary cells (rechargeable).

While a dry cell's electrolyte is not truly completely free of moisture and must contain some moisture to function, when it was first developed it had the advantage of containing no sloshing liquid that might leak or drip out when inverted or handled roughtly, making it highly suitable for small portable electric devices. By comparison, the first wet cells were typically fragile glass containers with lead rods hanging from the open top, and needed careful handling to avoid spillage. An inverted wet cell would almost certainly leak, while a dry cell would not. Wet-cell Gel Battery.

Primary wet cells

Daniell cell

The most famous wet cell is the Daniell cell, which is sometimes referred to as a crowfoot or gravity cell. The Daniell cell was developed in 1836 by the British chemist (and meteorologist) John Daniell as a source of steady electrical current

Secondary wet cells

A redox reaction that occurs is readily reversible allowing it to have a long, reliable, and useful life. In a car battery, the cell is recharged by the car's alternator.
