Batteries store direct current electrical energy in chemical form for later use, there are many classifications for the batteries according to their chemistry, construction, and applications.

Battery Classifications:

Chemistry classification:

The batteries divided into two major groups based on the types of chemical components used in acidic or alkaline media:-

  • • Nickel Cadmium batteries (Ni/Cd) usually called alkaline batteries.
    Use Nickel and cadmium alloy electrodes, and alkaline electrolyte e.g. Potassium Hydroxide.
  • • Lead Acid batteries (LA), usually called Acidic batteries.

Use Lead and Lead Sulphate electrodes and Sulphuric acid electrolyte.

Construction classification:

The batteries divided also into two major groups based on its construction:-

  • • Vented batteries, also called open batteries with removable caps.
  • • Sealed batteries with valve regulator, usually used for lead acid batteries (Valve Regulated Lead Acid -VRLA).
    The VRLA batteries classified to AGM or Gel groups based on the electrolyte media if it is Glass mate or Silica Gel.

Applications classification:
The battery is an essential part in many applications and equipment:-

  • • Automotive applications e.g.;Cars, Buses, Tractors, vans….etc.
  • • Traction applications e.g. lifting platforms, Electric tractors, forklifts, electric vehicles….etc.
  • • Stand-by applications e.g. UPS, Telecommunication systems,IT, utilities, general electronics and special applications required deep discharge like renewable energy systems.

batteries required for the PV systems are standby batteries designed to be discharged down as much as 80% time after time, and have much thicker plates.
