Let’s read intently.

How Long Do Car Batteries Last?

After replacing your car battery, the lifespan of it depends on 2 questions. How long can it hold its charge, and how much time it requires to get recharged?

If the battery can’t be recharged, be sure it is dead.

However, you will get a minimum of 6 years of service from your new car battery if you drive your car in an ideal condition like no harsh temperature or severe humidity.

How to Know if Car Batteries Need to be Replaced?

When a car battery starts dying, it will show a few warning signs. Pay attention to the reaction of your vehicle when it starts. This way, you can keep yourself hassle-free in the middle of the road with an inactive car.

Find the below 7 signs which will let you know that your car battery needs replacement.

  • Old Battery
  • Blotted or Misshaped Battery Case
  • Illuminated Check Engine Light
  • Slow Engine Crank
  • Common Electrical Problems
  • Corroded Battery Terminals
  • Severe Weather

1# Old Battery

As stated earlier, depending on the driving condition and weather, a new car battery's lifespan is 3 – 5 years. However, this statement is invalid for electric vehicle batteries.

Do you remember when you last replaced your car battery? Check the manufacturing date available in the case of your car battery. Inspect the battery if it passes 4 years from its manufacturing date.

2# Blotted or Misshaped Battery Case

The lifespan of a battery extremely gets affected by the wild climate. Your car battery will take an unfamiliar shape due to extreme weather.

Swell and crack may happen when your car battery gets exposed to excessive cold or heat too frequently. The acid may come out if leaking happens, and it is a dangerous thing. It would be best if you discarded your battery that is not rectangular.

3# Illuminated Check Engine Light

From your car check engine light, you can know if your vehicle engine is dying. When you see illuminated check engine light, don’t make it late. Firstly, read your vehicle manufacturer manual, and then call a mechanic to inspect if the engine works at its full capacity.

If they find that the battery is showing inefficient performance, replace it without hesitation.

4# Slow Engine Crank

The internal components of a car battery get inefficient and wear out over time. Generally, a vehicle engine should be running promptly. When it doesn’t happen, and you have to wait for a few more seconds for the engine to start, be sure something is wrong with your car battery. A slow start is usually the last breath of a battery before it kicks.

5# Common Electrical Problems

The car battery controls the functionality of different electrical components such as radios, lights of the dashboard, power windows, and wipers in the windshield. Failure in these electrical components' functionality tells that the battery of your car is on its last breath.

Unfortunately, these electrical problems can become worse compared to an inactive battery. If you face a severe electrical problem, buying or leasing a new car will be mandatory without repairing the problem.

Remember, the more components such as a smartphone charger if you plug into your vehicle, the battery will die faster.

6# Corroded Battery Terminals

If you ask a car owner what the reason for replacing your car battery is? Most of them will answer due to corrosion. When the battery acid leaks out at the connectors, it gets hardened. As a result, connecting points and terminal contact gets hampered. Simultaneously, recharge of the battery using an alternator can’t happen.

You can conveniently locate corrosion in the battery. If you find hardened blue-green powder in the terminal, be sure it happens due to corrosion.

In a few cases, cleaning this powder will increase the lifespan of your battery. Now one question might have popped up in your mind. What to use to clean the corrosion? Use a dry, soft cloth and a toothbrush for corrosion cleaning.

However, buying the best car battery is the best solution at this point.

7# Severe Weather

Car batteries are prone to premature failure when exposed to severe weather.

You will get 35% weaker performance from your car battery at 32° F. But the battery will act like it is performing at 100% efficiency. This way, the battery will become weaker and continuously fail to work at its best. Finally, it flops totally.

When the battery gets frozen completely, “electrical death” happens to your car battery. The truth is, this problem is unrepairable. At this point, you have no other choice except to buy a new battery for your vehicle.
