      Wet battery

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. These types of batteries are commonly available. These batteries are not tolerant  once they get discharged they do not recharge as other wet batteries do.
