Here and there this fume is vented out of the top vent blocks on the battery, however on different occasions, modest quantities of this fume spill out nearby between the posts and where they seal to the plastic battery packaging. This fume blends in with different gas in the engine, the warmth of the motor, the distinctions in the lead arrangement between the posts and the terminals, the copper of the battery wires, and makes Corrosion. In the engine of a vehicle, temperatures can surpass 250 degrees, and this warmth causes the metal of the posts and the plastic of the packaging of the battery to grow at various rates.
