We use a specialized "room temperature," mechanical separation process to recycle alkaline batteries. The alkaline battery components are separated into three end products. These items are a zinc and manganese concentrate, steel, and paper, plastic and brass fractions.Battery (electricity) | Engineering | FandomCell vs. battery Edit. Strictly, an electrical "battery" is an interconnected array of one or more similar "cells". That distinction, however, is considered pedantic in most contexts (other than the expression dry cell), and in current English usage it is more common to call a single cell used on its own a battery than a cell. For example, a ...Batteries - Oakton Community CollegeZinc Chloride Cells This cell is also referred to as a "heavy-duty" type battery. It is a modified zinc-carbon cell. It has little chance of liquid leakage because the cell consumes water along with the chemically active materials. The cell is usually dry at the end of its useful life.
