Stationary Lead Acid Battery

IEC 60896-22 is applicable to  :-

  1. All stationary Lead-acid cells
  2. Monobloc batteries of the valve regulated type
  • For Float charge application: They can be permanently connected to a load and d.c. power supply.
  • In a static location: not generally moved from place to place.

They are incorporated into stationary equipment or installed in battery room.

These kinds of batteries can be used in

  • Telecom
  • UPS
  • Utility switch
  • Emergency power or similar applications

Objective of IEC 60896-22 :- It specify the methods of tests for all types and construction of valve regulated stationary Lead acid batteries and monobloc batteries.

Does not applicable :

  • lead-acid cells and monobloc batteries used for vehicle engine starting applications
  • solar photovoltaic energy systems
  • general purpose applications

There is a list of tests performed on the batteries for safe operation characteristics, durability Characterstics & performance Characteristics.
