A car battery is one of those parts that are often overlooked until the time when your vehicle fails to start. It silently performs its task of powering up the vehicle on a daily basis but like all the other parts of the vehicle, its life too has an expiry date.
Thus, how long should a car battery last? Three to five years is the usual life span of car batteries on average. However, depending on different conditions and factors, the life expectancy may vary.
Knowing what actually impacts the life expectancy of car batteries can help you in avoiding any sort of surprise breakdown and prevent you from spending extra expense on replacing your battery due to its failure. In this article, we will discuss how long a car battery should last, its signs of wearing off, and some useful tips.
What Is the Average Lifespan of a Car Battery?
The average lifespan of an automobile battery is usually three to five years. This applies to ordinary lead-acid batteries that are used in most gas-powered cars.
There is, however, no definite lifespan. While some batteries start failing at the three-year mark, others keep working properly for as long as six years or even more.
Some of the things that affect your battery’s life include:
- Weather conditions
- How often you drive your car
- Electronic systems in your car
- How well your battery was made
- Battery maintenance practices
- The effectiveness of the charging system
When your battery nears its fourth year, it should be tested.
Factors that Affect Car Battery Life
It is important to know that not all batteries have the same lifetime. Find out below what affects battery lifetime most.
1. Climatic conditions
The climate greatly influences the lifetime of a battery.
High temperatures can cause the quick exhaustion of a battery. It happens because high temperatures provoke the chemical processes within the battery, leading to quicker evaporation of the battery fluid and degradation of its parts.
In cold weather conditions, batteries are less efficient in starting the engine due to the slowing down of the chemical processes. However, in cold weather conditions, the battery does not degrade as fast as in hot weather conditions.
Drivers who reside in areas where the climate is very extreme may find that their batteries run out quicker than those who reside in moderate climates.
2. Driving Patterns
Your driving habits have a direct effect on the battery’s efficiency.
Daily short trips prepares the alternator to recharge the battery efficiently after each trip. This repeated practice wears out the battery gradually.
Long trips allow the charging system ample time to recharge the battery. If your car is used mostly for short trips, try to drive it once in a while for a long distance.
3. Staying Unused for Long Periods
When cars are left unused for weeks or months, battery issues may arise.
Even if the engine is turned off, modern cars draw current even when the engine is not on, to run various electronics such as security systems, computerized equipment, and keyless entries. The current keep draining the battery slowly. In this case a battery maintainer prevent this from happening.
4. Electrical Accessories
Automobiles have become increasingly dependent on electrical components over time.
Components like:
- Heated seats
- Navigation systems
- Dash cameras
- Phone chargers
- Audio systems
- Interior lights
All the above factors lead to greater load on the battery. The use of electrical accessories even when the engine has been switched off can drain your car’s battery much sooner than you think.
5. Battery Quality
All batteries do not come in equal quality.
Higher quality batteries are made using superior materials and have high reserve capacities, and may come with extended warranties. Even though such batteries may be expensive at first, they might prove cheaper over time. Picking the right battery for your car is equally important as picking the best battery brand.
Signs Your Car Battery Is Going Bad
Knowing the warning signs can help you replace your battery before it leaves you stranded.
Slow Engine Turnover
When the engine turns over slowly when you are starting the car, the battery could be failing to produce sufficient power.
This is usually among the first symptoms that your battery is failing.
Dashboard Battery Warning Light
The battery warning light does not always suggest there’s a problem with the battery.
Sometimes, it shows problems with the alternator or the charging system. However, the problem needs to be checked as soon as possible.
Dim Headlights
A weak battery cannot deliver proper power to certain parts of the vehicle. If your headlights appears dim when starting the car or if the interior lights are flickering, it could be the reason that your battery needs to be replaced.
Quick Click While Turning Over
The most common reason for quick clicking is that the battery lacks enough charge for the motor to start. This is usually the case when the battery is close to dead or has reached the end of its life.
Battery Terminals with Corrosion
When there’s white, blue, or green deposits on the battery terminals, it hampers the flow of electricity. While cleaning can help, if there’s too much corrosion, it mean the battery is old and needs to be replace.
Swollen Battery Case
High temperatures can make the battery casing bulge out. Such batteries need replacement since the internal workings are affected by such swelling.
Tips to Extend Battery Life
However, even though batteries have a limited lifespan, you can increase it significantly through proper treatment.
Drive Your Vehicle Regularly
Regular driving ensures that the alternator charges the battery completely. If possible, try not to leave your vehicle unused for long periods of time.
Turn All Accessories Off Before Locking Your Car
Switch off the lights and other electric devices before locking your car. Even small amount of electricity consumption can drain the battery at night.
Maintain Clean Battery Terminals
The dirt on terminals can decrease charging ability due to increased electrical resistance. Regular cleaning of terminals is necessary to maintain proper connection.
Secure the Battery Properly
An insecure battery installation leads to vibrations during driving. Vibration damages the battery components and thus decreases its lifespan.
Test the Battery Regularly
Almost every repair service or auto store can do a quick battery test. Such testing is essential especially after three years of the battery life.
When Should You Replace Your Car Battery?
A lot of people replace their batteries only after they fail. A better way is to change it before it fails.
Some reasons you should think about changing your battery include:
- If the battery is over four years old.
- If starting up the engine is becoming difficult.
- If the tests for the battery indicate a drop in its capacity.
- If the battery needs constant jump starting.
- If the battery casing is bulging or leaking.
Can a Car Battery Last More Than Five Years?
Yes, some batteries last more than five years.
People who live in mild weather areas, perform routine maintenance on their cars, and frequently travel long distances can increase their battery’s lifespan.
Nevertheless, even though the old battery works fine, suddenly it can stop working efficiently. If your battery is close to six years old, it is better to replace it.
Does an Electric Vehicle Battery Last Longer?
Many people mistakenly think that car batteries and batteries in electric cars are the same. However, a standard 12V battery can only last for three to five years.
Electric cars have a bigger battery called a high-voltage battery pack that runs the vehicle. This type of battery pack is built to last longer, which can be 8 to 15 years or more. However, the 12V battery pack in an electric car has the same life span as that of a normal car.
Final Thoughts
So, how long should a car battery last? Under normal circumstances, you can generally expect from three to five years of reliable use. There are various factors that determine how long it will operate properly, such as weather, your driving style, maintenance, and even the quality of the battery itself.
Knowing possible warning signs, scheduling check-ups regularly, and maintaining the battery can help avoid surprises. It is better to keep track of its condition as it ages, rather than face the situation where your car won’t start at all.
A healthy battery serves more purposes besides starting your engine since it plays a crucial role in the operation of every electrical system in your car.
