Like everything, car batteries have expiry dates. Also your car battery is like its heart: without it, your car doesn’t have the power to start, move, or do anything else. So it’s important to understand at least a little bit about your battery and to know the most common signs that shows it’s time to replace it.
1.) Slow Engine Crank:
When you attempt to start your car, the cranking of the engine is sluggish and takes longer than normal to start. 94% of the time, it’s really your battery.
2.) Check Engine Light:
When the check engine light appears on your driver’s side cluster, that’s where you have your speedometer and other indicators, it sometimes means your battery power is weak.
3.) 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.
4.) Swelling or bloated 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.
5.) Battery Leakage:
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.
6.) Old Age:
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.
This knowledge is important because it gives you early indication to know when to replace your car battery. Better safe than sorry.
