dry cell
"An early name for the non-rechargeable battery that is still used occasionally. The early non-rechargeable batteries were laboratory devices (see, e.g. the Daniell cell). To produce a practical device, the electrolyte solution was ""immobilized"" by some gelling agent, and the whole cell was sealed to permit its use in any position. Hence the name: ""dry cell."" See also Leclanche cell. And an Encyclopedia Article. "

dry cell (Leclanché cell)
A electrolytic cell that uses a moist paste rather than a liquid as an electrolyte . Flashlight batteries are dry cells with a zinc cup for an anode , a carbon rod for a cathode , and a paste made of powdered carbon, NH4Cl, ZnCl2, and MnO2 for an electrolyte.

Dry cell
A dry cell is a galvanic electrochemical cell with a pasty low-moisture electrolyte. A wet cell, on the other hand, is a cell with a liquid electrolyte, such as the lead-acid batteries in most cars.
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. Lead-acid batteries would not achieve the safety and portability of the dry cell, until the development of the Gel Battery.
