How Long Do Car Batteries Last? Quick Answer

Do you curious about How Long Do Car Batteries Last? Car batteries are a crucial element of a vehicle. Batteries provide your automobile with the zap to keep going, from starting it to charging your phone while you’re out and about. Because of this, it’s crucial to understand when to start thinking about replacing your car batteries and how you can make their lives longer.

How Long Do Car Batteries Last?

Some car batteries can last for a maximum of five or six years, while others only last for two. You should change your car’s battery approximately every three to four years. Change your car’s battery as part of regular repair.

Signs Your Car Battery Is Dying

There are a few important signs that are reliable indicators that your battery is nearing the end of its useful life. The ‘check engine’ light ON is the first contributing element. This typically indicates a sluggish battery, though the alternator in your car may also be to blame.

Please pay attention to how your car starts and responds to you. Keep checking the battery to prevent being stranded in the center of nowhere with a dead car. Following are seven warning signals that your automobile battery is failing:

Difficult-To-Start The Vehicle

Your battery’s internal parts will deteriorate and lose efficiency over time. When this occurs, the engine won’t start immediately since the battery needs more time to build up a charge for the starter. Usually, a battery’s final effort before dying is a slow start.

Dim Lighting And Technical Difficulties

The battery runs all of the electronics in your car, including the lights, radio, and dashboard computer. These devices won’t operate as efficiently if the battery depletes its charge. The more things you connect to your car while moving, like a phone charger, the faster your battery will die.

Check Engine Light Is Lit

The check engine light may illuminate when your battery is close to low in most vehicles and might signal almost anything. To ensure your battery operates at its maximum potential, check your manual and have a mechanic examine it. If not, you ought to have it changed.

Bad Smell

The battery may leak gas due to damage or an internal short. When you open the hood, the smell of rotten eggs can be coming from a leaking battery. Bring it in to be examined. The mechanic will inform you of the following procedures and whether the battery needs to be replaced.

Deteriorating Connectors

Have you noticed a whitish, ashy substance on your battery’s metal components? You have a corrosion problem. Corroded terminals, the positive and negative metal connectors on the battery’s top, might cause voltage problems and make it hard to start your vehicle.

An Unattractive Battery Casing

Your battery’s longevity may suffer from the harsh prairie climate. A battery case may bloat and shatter if exposed to too-hot or too-cold temperatures. Your battery may not be operating properly if it is not rectangular.

A Dated Battery

Even though it goes without saying, it’s easy to forget how long it’s been since you had your car’s battery checked. Have you recently replaced your battery? Under perfect conditions, a car battery will last anywhere from three to five years.

The battery’s life can be cut short by the weather, computer requests, and how you usually drive. If your battery is getting close to 3 years old, it’s best to be safe and have it checked often.

Car Battery Maintenance

Your battery needs to be maintained, just like your car. Here are some pointers for keeping your automobile battery in good shape:

Garage

Consider turning off the security system if you can park in a secure garage. Leaving it on will soon deplete the battery. Drive your car regularly for 30 minutes once a week if you have to leave the security system on; this will keep the battery in good condition.

Recurring Automobile Trip

Driving your automobile for 30 minutes a week will keep the battery charged, as already explained. It might not be enough to recharge the battery if you take short drives in your automobile because there won’t be enough time.

Inspect the fluids and test a car battery.

Ask the mechanic to do a car battery test and a fluid check when you bring your car in for servicing. If it has to be changed, it may be done while the car is being serviced, so you won’t have to tens about it breaking down unexpectedly.

Heater Block

Consider installing a block heater if you still need to get one. Because of the harsh winters in Manitoba, starting the car is made simpler by easing the strain on the battery. It’s a simple action that will lengthen the life of your battery.

Different Car Battery Types

Although there are many different kinds of automobile batteries available, the majority of batteries used to start internal combustion engines and supply electricity to the electrical system typically fall into one of two categories: A conventional wet cell or flooded battery, which may need routine maintenance, or a sealed, low maintenance battery, sometimes known as a valve-regulated lead acid (VRLA) battery.

The two main categories also come in a wide range of sub-variations. The two most well-known types are the Enhanced Flooded Battery (EFB) and the Absorbent Glass Mat Battery (AGM). Both types are intended to have strong specifications and longer lifespans. Battery packs used in EVs and hybrid cars are substantially bigger and more complex than those described here.

Why Don’t Car Batteries Last Longer?

Simply put, a classic wet cell or flooded automobile battery comprises lead and other metal plates dissolved in a key of two-thirds water and one-third sulfuric acid. The mixture functions as a battery to store electricity, but over time, the acidic mixture weakens the battery by eating itself.

Heat is another major enemy of battery life, along with time. Expect significantly shorter automobile battery life if you reside in a hotter-than-usual location, such as a desert city where triple-digit temperatures are the norm for many months of the year.

The solution within your battery is evaporating due to that heat. The temperatures inside the engine compartment can be extremely high under heavy operation, even in more moderate locations.

Vibrations inside your battery are another threat. It speeds up the deterioration of the battery case’s internal plates, which are soaking in acid.

A car battery’s lifespan can also be shortened by undiscovered charging system problems such as a defective alternator, worn, incorrectly adjusted, or damaged belts or regulators, and electrical faults.

Finally, there are the “oops” mistakes. For instance, even though many current cars have safety features built-in, it is still possible to leave the interior or headlights on in a parked car, which might result in the battery dying.

The automobile may usually be restarted with a jump start, although frequent full discharges of this nature reduce the battery’s lifespan. 

A worse issue may be present if the battery terminals are overly corroded. For the greatest performance, check their tightness and condition occasionally.

Can I Increase The Battery Life Of My Car?

Although only a little can be done about the weather, vehicles with batteries situated remotely instead of inside the engine have an advantage. The rear seat or trunk are two typical remote positions, which will lessen heat exposure.

However, a battery’s lifespan can be increased with proper maintenance. Double-check that the battery is firmly connected to the tray to avoid excessive vibration. Verify the condition of the belts and alternator in the charging system.

Periodically examine the terminals for tightness and corrosion accumulation if the battery is visible. While the terminals should be snug, avoid overtightening them.  

Also, if your vehicle doesn’t automatically turn off interior and exterior lights when the engine is turned off, double-check them before pulling into a parking space. A battery tender or charger can extend the life of your battery and keep it from running out of juice if you leave your car parked for an extended period or don’t use it frequently.

Conclusion

In conclusion of How Long Do Car Batteries Last? Several variables, such as the battery’s kind and quality, the environment, the driver’s behaviors, and maintenance procedures, can affect how long a car battery lasts. Car batteries commonly last 3-5 years on average. It’s crucial to remember that this estimate is subject to wide variation.

Drivers can increase the life of their car batteries by following appropriate maintenance procedures, including maintaining clean battery connections, avoiding deep discharges, and routinely checking the battery’s voltage and electrolyte levels.

The battery’s lifespan can also be prolonged by being aware of harsh weather conditions and taking the required precautions, such as employing battery blankets in cold locations.

Ultimately, consistent performance and reduced unforeseen breakdowns on the road can be achieved by understanding the aspects that affect a car battery’s lifespan and taking proactive measures to maintain it.
