Batteries Testing

• Battery/cell is one of the most critical source
  of power in most of the electronics products use
  widely. These play a very important role in
  product designing and also on product life. These
  are very useful and in the same way very
  dangerous if not use as per technical
  requirements and instruction.

 PURPOSE OF A BATTERY

• The primary purpose of an battery is to provide a
  source of electrical power for starting and for
  electrical demands that exceed generator output.
  The battery is a voltage stabilizer because it
  acts as a reservoir where large amounts of
  current (amperes) can be removed quickly during
  starting and replaced gradually by the generator
  during charging.
• The battery must be in good (serviceable)
  condition before the charging system and the
  cranking system can be tested

How Battery Works

• A fully charged lead-acid battery has a positive
  plate of lead dioxide (peroxide) and a negative
  plate of lead surrounded by a sulphuric acid
  solution (electrolyte). Difference in potential
  (voltage) between lead peroxide and lead in acid
  is approximately 2.1 volts. During Discharging
  The positive-plate lead dioxide ( PbO 2 )
  combines with the SO 4 from the electrolyte and
  releases its O 2 into the electrolyte, forming H
  2 O . The negative plate also combines with the
  SO 4 from the electrolyte and becomes lead
  sulphate ( PbSO 4 ).

Why Test Battery System
There are two main reasons to test a battery 1-
To insure the supported equipment is adequately
backed up. 2- To prevent unexpected failures.
