Cell and battery?

Question

Cell and battery?
Is there a difference between a cell and a battery?
What ia a primary wet and dry cell?

Answer 1

A 9V battery uses 6 cells at 1.5 volts to get 9 volts. A "AA" is a cell and not a battery in a technical sence. However in common usage even manufactures say "batteries not included" when they should say "cells not included".

Primary batteries are not rechargable. Secondary batteries are rechargable.

Wet cells have liquid electrolytes that can spill. Dry cells have a paste for an electrolyte that does not spill.

So we have
9V........... primary dry battery
AA........... primary dry cell
12V car... secondary wet battery
AA NiCad.secondary dry cell

Answer 2

A cell is the single unit of an electrolytic cell which produces electricity from a chemical reaction between two dissimilar electrodes. A battery is a group of cells, some of which may be in series and some in parallel, to provide electricity at a higher voltage (say 6V or 12V) and heavier current.

A wet cell has sulphuric acid where as a dry cell has a paste of electrolyte (off-hand can't remember its composition).

Answer 3

Cell is a single unit and battery is nothing but more than one cells are connected together. Dry cell is the one normally we use in the battery light.Usually not rechargeable. The wet cell will have water and H2SO4 acid mixed together. Old types of wet batteries need to check the level of acid and water frequently. Now non maintenance batteries have come to the market . No need to check the water and acid level. It is kept in paste form.

Answer 4

a battery is a collection of cells connected together
