8 indications that it’s time to change the car battery

Nothing is more annoying than trying to start your car on a chilly morning to go to work only to find that it won’t start. Everything appears to be in working order under the hood when you look for the issue; the battery compartment is the only exception. You notice several telltale signs that your automobile battery needs to be replaced, including corroded terminals, an unpleasant odor, and even a misaligned battery casing. As a result, you are compelled to call a mechanic to replace it and mend all the broken parts. 

One of the key components of your car is the battery. You require it not just to start your car’s engine but also to power all of the electrical features like the lights, radio, GPS, climate control, etc. A car battery should ideally last for four years before needing to be replaced. The battery may, however, prematurely expire for a variety of reasons, necessitating an earlier replacement. We list 8 indicators that it’s time to replace your car battery in this brief guide. 

1. Slow engine start 

Does it take a long time for your engine to start hummering? The battery may just be unable to maintain the same level of charge as it formerly could and may even be progressively decomposing. As soon as you can, think about replacing it before it completely dies. 

2. Headlights Dim 

If the headlights on your automobile are not as brilliant as they once were, it may be because the battery is running low on power. Take it outside and have it recharged. 3. Foul Odor If the issue continues, it can be a sign that your battery needs to be replaced because it is dying. 

A telltale symptom that a battery is leaking gas and has malfunctioned is when it emits an unpleasant odor, akin to that of rotten eggs. Keeping such a battery could be hazardous and harm or corrode other car parts. Have it changed right away. 

4. Engine Rumbles but Is Unable to Start 

Most of the time, if your car engine turns over but won’t start, the issue may be with your car battery, which may not be providing enough volts to start the engine. Remove the battery, have it refilled, then replace it. Alternately, you might use jumper cables to jump-start your automobile and keep it going for around 30 minutes. The car should restart normally this time. The battery would need to be changed if it didn’t. 

There is no way of knowing how long the old battery’s charge will remain, even if the automobile is functioning normally. Buy a backup battery as a precaution, lest you find yourself stranded in the middle of nowhere because your primary battery failed exactly when you needed it most.

5. It Had Already Been Jumped A Lot 

Even cars with reasonably new batteries may require a jump start for a variety of reasons. You might have forgotten to switch off the car’s lights, started it after a long period of inactivity, or there was a starting issue. Nevertheless, the battery might only need to be changed if it was jumped more than three times in a single week. 

Your car battery takes a lot of strain when you jump it, and if you do it repeatedly, it will get damaged more quickly and lose life. Ironically, a damaged battery would require additional jump-starting to function and would so sustain more damage. Additionally, you run the risk of damaging your starter and alternator. By exchanging the old battery with a new one, you can spare yourself the trouble and the expense of repairs. 

6. Uneven Case 

Your automobile battery’s case may bulge and shatter due to high temperatures as well as an accumulation of too much acidity. It’s time to get a new automobile battery if you find that it is not a rectangular shape with straight sides. 

7. It’s already out of date. 

As was already said, a car battery has a typical lifespan of 4 years. Well done if you’ve maintained the battery longer and it’s still operating normally! Your car appears to be nicely taken care of by you. The best course of action is to exercise caution and have the battery’s functioning checked on a regular basis. This should begin once the battery has been in use for three years for the majority of people. 

8. Too Much Corrosion is Forming Too Quickly 

It is typical for corrosion to accumulate around the battery, even around the terminals. This occurs as a result of the outside factors that the battery is frequently exposed to. Often, you can utilize a dependable auto rust remover to stop it from spreading into the jointing components. It’s possible that the battery is broken and has to be replaced if you observe that the region around it is corroding excessively and too soon. Frequently, a leaky battery or one with insufficient interior fluid levels can cause significant corrosion.

What Elements Influence Battery Life? 

The lifespan of a car battery can be affected by a variety of variables. The main causes include hot weather, a bad charging system, and a buildup of corrosion and grime. 

Car batteries have a shorter lifespan in hotter climes. This is due to the increased risk of interior structure damage brought on by higher temperatures’ increased chemical activity. Additionally, the acidity of the liquid inside wet batteries rises in warmer temperatures due to the ease with which it evaporates. 

A poor charging method can potentially shorten the life of a car battery by prematurely draining it. The most frequent cause of risk is an alternator that isn’t working properly and either doesn’t output enough power or keeps the charging circuit going even when the car’s engine is off. 

Finally, grime, grease, and corrosion can make the circuits around the battery less effective and hinder current flow, putting additional strain on the battery and hastening its demise. 

Is A New Battery Needed To Be Charged? 

This used to be the case, however in modern times, car batteries may be put into your vehicle right out of the box and are already completely charged. Verify that the battery you bought came from a reputable manufacturer or merchant.
