      Wet battery

Car Battery Types and Sizes

Wet cell battery is classic lead acid accumulator which has been inclusively designed for the automobiles. Wet cell batteries require maintenance after some period.  wet cell batteries use semi solid electrolyte and these are fully sealed. Modern day batteries of this kind are tightly sealed and do not require any maintenance. Whereas, old wet cell batteries require maintenance regularly as those were using water as electrolyte which evaporates due to hot weather and also due to extensive heat of the vehicle engine.

For the usage of wet cell batteries which use water,  use distilled water as electrolyte otherwise you would end up damaging your car battery.

In the Wet category, there are two types of Sub Categories:

1.      Deep Cycle battery

Deep cycle batteries  commonly use in marine industry, especially designed for long lasting than others. These types of batteries can bear charges for long time, and are resistible even when fully discharged. And special feature of these batteries is they provide stable charging for long time.

2.      Starting, Lighting and Ignition (SLI) batteries

These batteries have only three functions (starting, lighting and igniting). Once  ignite the engine of vehicle, their alternator takes over and supplies power to system.

1.      Gel

These batteries are very resistant to temperature, heat and vibrations. Their electrolyte is gel type liquid instead of normal liquid.

2.     AGM

Absorbed glass mat batteries have been designed in a very smart way. Electrolyte is placed in glass mats which are composed of thin fibers meshed together to form a compact mat.

 Which types of car batteries are used in cars?

  • Batteries selection based up vehicle engine, model, battery plate size and most important your budget.
  • Wet cell batteries are cheaper than dry batteries.
  • Brand of the battery does matter to the extent in case of brand conscious, otherwise stick to the market going product, (AGM,EXIDE, EVERSTART) and many others in the same category.

 What is the group size on a car battery?
