When does a car battery need to be replaced or time for a new battery ?
The battery is what powers every electrical component in a car. At some point, the car battery needs to be replaced, but when? Is there a way to tell that the battery is failing? How long does it last? Let’s start with why the battery needs to be replaced. Most cars have lead-acid batteries that are made of six cells with lead and lead-oxide plates filled with an electrolyte (dilute sulfuric acid).
Slow engine crank:
When you attempt to start the vehicle, the cranking of the engine is sluggish and takes longer than normal to start.
Check engine light:
The check engine light sometimes appears when your battery power is weak.
Low battery fluid level:
Car batteries typically have a part of the casing that’s translucent so you can always keep an eye on your battery’s fluid level. If the fluid level is below the lead plates : (energy conductor:) inside, it’s time to have the battery and charging system tested.
The swelling, bloating battery case:
If your battery casing looks like this you can blame excessive heat for causing your battery case to swell, decreasing your battery life.
Leaking also causes the corrosion around the posts : (where the + and – cable connections are located.: ) The gunk may need to be removed; otherwise, your car may not start.
Your battery can last well beyond three years but, at the very least, have its current condition inspected on a yearly basis when it reaches the three year mark.
