2. Industrial batteries:
This kind of batteries are used to supply power in heavy duty applications like machinery, railroad and backup power for data centres, utilities and telecommunications.
The various types of industrial batteries are as follows:
i). Absolyte battery:
These are the large kind of batteries, made up of lead acid and cadmium. It is ‘vented VRLA(Valve regulated, lead-acid battery). It is used in the telecommunications system, railroad switchgear and signals, and in solar arrays.
ii). Large Flooded Cell:
As the name suggests, these are the large batteries, typically a lead acid, vented battery. It comes in rectangular or in hard case formats. These batteries are used in Stationary power and in utility systems.
iii). Nickel Iron:
These batteries vary in size from Medium to Large. These are flooded cell, vented batteries and are rechargeable. These batteries are very long lasting batteries. They come in rectangular or in metal cases. These batteries are used in railroad signals, mining operations.
