Why Does A Car Battery Need Water. Five or more years for a car battery. Keep some baking soda and water handy in case you get some acid on you.
To add water to your car battery open the vent caps and place them upside down not on the side so that the underside of the caps does not pick up any impurities that can contaminate the battery water. Keep some baking soda and water handy in case you get some acid on you. When this happens especially during the hot summer months the water in the electrolyte solution will evaporate and escape through the vents in the caps.
Watering your lead acid battery is an essential maintenance step that cant be skipped.
Just like how you cant go without water neither can your battery. At 248 volts per cell which is 80 of full charge the water in the acid starts to disassociate into hydrogen and oxygen gas which form bubbles that rise to the top. Just like how you cant go without water neither can your battery. Add water to the battery to bring the level to just below the bottom of the cell inspection hole.
