WHAT IS AN ALKALINE BETTERY?
• An alkaline battery is a type of
primary battery that derives its
energy from the reaction between
zinc metal and manganese dioxide.

Advantages of Alkaline Battery
Disadvantage of Alkaline Battery
• This has high energy density.
• This battery performs equally well
in both continuous and
intermittent applications.
• This performs equally well in low
and as well as high rate of
discharge.
• This also performs equally well at
ambient temperature as well as at
low temperature.
• Alkaline battery has also low
internal resistance.
• It has enough longer self life.
• Leakage is low in this battery.
• It has better dimensional stability.
• Alkaline batteries also have a high
internal resistance. This reduces
the power output of a battery. In
addition, while they are not as
prone to leaking as some other
types of cells and batteries, alkaline
batteries will leak if left in devices
unused for too long.

USES OF ALKALINE
BATTERIES
• Various types of this battery are there and different
batteries are used for different purposes. Like, nickel-iron
batteries are used for propulsion of industrial trucks and
mine locomotives. In air conditions also, this type of
battery is used. Another type of alkaline battery is Nickelcadmium battery; they get used in commercial airlines,
military airplane for initiating the main engine. So, we
can say that the alkaline battery is mainly used in moving
vehicles and industrial purposes.

CAPACITY OF AN ALKALINE
BATTERY
• The capacity of an alkaline battery is greater than an
equal size zinc chloride cell because the manganese
dioxide is purer and denser, and less space is taken up by
internal components such as electrodes. An alkaline cell
can provide between three and five times the capacity of
an acidic cell.

VOLTAGE OF AN ALKALINE
BATTERY
CURRENT OF AN ALKALINE
BATTERY
• The nominal voltage of a
fresh alkaline cell as
established by
manufacturer standards
is 1.5 V.
• The amount of electrical
an alkaline battery can
deliver is roughly
proportional to its
physical size. This is a
result of decreasing
internal resistance as the
internal surface area of
the cell increases.

CONSTRUCTION OF ALKALINE
BATTERY
• Alkaline batteries are manufactured in standard
cylindrical forms interchangeable with zinc–
carbon batteries, and in button forms. Several
individual cells may be interconnected to form a
true "battery", such as the 9-volt PP3-size.
