Types of Batteries

Starting, Lighting, Ignition (SLI) Batteries

  • Are used by most people every day and are produced in greater numbers than any other type of lead acid storage battery
  • They are used to start automobiles and most other kinds of internal combustion engines
  • Automotive SLI batteries are usually lead acid type and are made of six galvanic cells in series to provide a 12 volt system
  • Heavy vehicles such as trucks may have 2 batteries in a series for a 24 volt system, or may have a parallel string of batteries.

Examples: automotive, marine, truck.

Traction or Motive Power Batteries

  • An electrical vehicle battery (EVB) or traction battery is a rechargeable battery used for propulsion of batteries electric vehicles (BEVs)
  • Electric vehicle batteries differ from SLIs because they are designed to give power over sustained period of time.

Examples: forklifts, electric golf carts, riding floor scrubbers, electric motorcycles and other electric vehicles.

Stationary Batteries

  • These are often used for emergency power or uninterruptable power supply applications
  • They are shallow-cycle batteries intended to remain close to fully charged for the majority of their lifetime with only occasional deep discharges.

Used Non Lead Acid Batteries

Alkaline Dry Cells

  • Are 1.5 volt or multiples of 1.5 volt
  • Called heavy duty, general purpose, zinc carbon or zinc manganese
  • Commonly Energizer or Duracell
  • Generally non-rechargeable.

Non Alkaline Dry Cells (including Rechargeable)

  • They are 1.2 volt or can be multiples of 1.2 volts
  • Often rechargeable such as NiMH, NiCad, Lithium Ion
  • Commonly found as packs (e.g. mobile phones, laptop computers, power tools.

Non Lead Acid Wet Cells

  • Filled with aqueous electrolyte solution
  • Mostly contained within a steel or solid box of individual cells of 1.2 volts to make a 12 volt battery.
