Usually, old car batteries have issues and are the common causes of smoking car batteries.

Sometimes you don’t have to wait a year to change your battery, especially if you notice a shift in its performance.

Using Batteries with Incorrect Size

Batteries are available in different sizes to suit various cars; hence, it would be best to ensure that you use the specified battery.

Do not go for the smaller batteries since the charge drain will be faster, leading to battery complications.

As for the more extended battery, they will take longer to charge and may not work well with your car.

You must be careful with how you handle the car batteries’ acid.

In that case, taking the necessary precautions when handling batteries is essential.

Keep off from the terminals and ensure that water doesn’t go near them to prevent corrosion, eventually leading to a smoking car battery.

When Should You Add Water to a Battery?

It is common to see a car owner add water to their car battery.

But, the main problem is that some people add the water without thinking about the consequences and whether their move is right.

So, when should you add water to your battery?

You can only add water to your battery after it charges for expansion.

After fully charging the battery, let it cool, and later add water for expansion.

This move is effective since it prevents boil-overs which can be dangerous for your car battery.

What Happens When a Car Battery is Overcharged?

Many experts often comment about car batteries mentioning that you must never let the batteries overcharge.

The main reason is that overcharging leads to excessive gassing- a situation where your battery generates hydrogen and oxygen.

Excessive gassing is dangerous in car batteries since it can cause a buildup, eventually leading to a battery burst.

Naturally, after the car battery bursts, it is fair to say that the battery is dead and won’t perform the necessary duties.

Also, overcharging is one of the leading causes of a smoking car battery.
