Factors That Affect Car Battery To Die Soon:

With the growing demand for electric vehicles, everyone wants to know why car batteries die quickly. The answer is that there are a number of factors that can lead to battery failure and we’re going to focus on three main ones in this article. The first factor is temperature as hotter temperatures will increase power loss in the battery; second, driving patterns which affect how often you use your car or if it’s sitting idle for long periods of time; third, age – all batteries experience an aging process and eventually wear out over time from natural causes such as corrosion.

15 Reasons That Cause A Car Battery To Die Quickly:

Here are a few of the most common culprits.

1. Temperature

2. Driving Patterns

3. Age

4. Overcharging

5. Undercharging

6. Electrical Current Leaks

7. Sulfation

8. Electrolyte Level Too Low

9. Corrosion

10. Loose Battery Cable Connections

11. Faulty Alternator

12. Bulky Accessories

13. Lights Left On

14. Ignition Switch Problems

15. Starting the Car in Extreme Cold Weather.

Temperature: 

The hotter the temperature, the more power is lost in the battery. In fact, at temperatures over 104 degrees Fahrenheit, the battery will no longer work at all. This is why it’s important to keep your car’s battery cool by using a battery cooler or insulated cover – especially in the summer months.

Driving Patterns: 

Driving your car regularly will help to keep the battery in good condition, while periods of extended idling or infrequent use can lead to battery failure. This is because the battery isn’t getting a chance to fully recharge and can eventually die.

Age: 

All batteries experience an aging process and eventually wear out over time from natural causes such as corrosion. The average car battery has a lifespan of 3-5 years, but this can vary depending on the make and model of your vehicle.

Overcharging: 

When you charge your battery too much, it can cause the water inside the cells to evaporate. This leads to gas build-up which can eventually damage the plates and connectors in the battery.

Undercharging: 

If you don’t charge your battery enough, it can cause the water inside the cells to evaporate. This leads to sulfation which is a build-up of lead sulfate on the battery’s plates. Sulfation makes it difficult for the battery to generate current, and can eventually lead to battery failure.

Electrical Current Leaks: 

Electrical current leaks can occur when there is a problem with the car’s wiring or electrical system. This can cause the battery to discharge even when the car isn’t running, leading to a quick loss of battery power.

Sulfation: 

Sulfation is a build-up of lead sulfate on the battery’s plates. Sulfation makes it difficult for the battery to generate current, and can eventually lead to battery failure.

Electrolyte Level Too Low: 

If the electrolyte level in the battery is too low, it can cause the plates to corrode and eventually die.

Corrosion: 

Corrosion can occur when there is a problem with the battery’s casing. This can cause the plates and connectors to rust, leading to a loss of power.

Loose Battery Cable Connections: 

Loose battery cable connections can occur when the cables are not properly attached to the battery or when there is a problem with the car’s wiring. This can cause a loss of power and damage to the battery.

Faulty Alternator: 

A faulty alternator can cause the battery to discharge even when the car isn’t running, leading to a quick loss of battery power.

Bulky Accessories: 

Bulky accessories such as a tow bar or roof rack can put extra strain on the battery, causing it to die more quickly.

Lights Left On: 

Leaving the lights on in your car can drain the battery quickly, especially if the engine isn’t running.

Ignition Switch Problems:

 A faulty ignition switch can cause the battery to discharge even when the car isn’t running, leading to a quick loss of battery power.

Starting the Car in Extreme Cold Weather: 

When you start your car in extremely cold weather, the extra load on the battery can cause it to die quickly.

Tips On How To Extend The Life Of Your Car Battery:

  • Keep your car’s battery cool by using a battery cooler or insulated cover – especially in the summer months.
  • Drive your car regularly to keep the battery in good condition.
  • If you don’t drive your car often, try to give it a good charge before using it.
  • Make sure the electrolyte level in the battery is always topped up.
  • Keep the battery clean and free of corrosion.
  • Check the battery cables for damage or looseness.
  • Make sure the alternator is working properly.
  • Avoid using bulky accessories that can put extra strain on the battery.
  • Don’t leave the lights on in your car when the engine isn’t running.. Start your car in warm weather instead of cold weather to avoid extra load on the battery.
  • If your car has a battery warning light, take it to a mechanic to have it checked.
  • Replace the battery if it’s more than three years old or showing signs of wear and tear.

Conclusion:

So what’s the takeaway? If you want to keep your car battery in good shape for as long as possible, heed our advice and avoid doing any of these things. Also, consider investing in a high-quality car battery charger that way, you can give your battery a quick boost whenever it starts to run low.
