A Battery is a portable source of energy

Technically, a cell is the basic electrochemical unit that generates or stores electrical energy. Simply put, a Cell is a single unit. When two or more electrochemical cells are electrically interconnected in an appropriate series/parallel arrangement to provide the required operating voltage and current levels it becomes a battery. Again simply put, when two or more cells are connected, they form a Battery. Under common usage, the term "battery" is often also applied to a single cell.

A cell with immobilized electrolyte. The term "dry cell" is often used to describe the Leclanche cell

The electrode in an electrochemical cell where oxidation takes place. During discharge, the negative electrode of the cell is the anode. During charge, the situation reverses and the positive electrode of the cell is the anode.

Batteries can be classified into PRIMARY (Non-rechargeable) SECONDARY (Rechargeable) & PHYSICAL
PRIMARY - Zinc-carbon, Alkaline and Silver Oxide
SECONDARY - Lead acid and Nickel Cadmium varieties
PHYSICAL - Solar Powered Cells

NIPPO manufactures Zinc-carbon variety.

NIPPO batteries are popularly used in Torch Lights, Transistors, Radio, Tape Recorders, Cameras and Camera Flashes, Personal Stereos, Quartz Wall Clock, Calculators, Remote Controls of TV, Battery Powered Toys, Hearing Aids, etc.,

Nominal voltage of a battery is 1.5V. All Nippo batteries role out of the factory with more than the nominal voltage of 1.5 Volts

The duration of storage under specified conditions at the end of which a cell or battery still retains the ability to give a specified performance.
