A car battery’s lifespan is determined by how long it can keep a charge and continue to recharge. Because there are various car battery kinds, the average car battery life is also dependent on its chemical makeup.
So, how long does it take for a car battery to die?
The average battery life of various common automotive batteries is as follows:
- Lead acid battery: The usual life of a lead acid battery is 3-5 years.
- GEL and AGM Batteries: These are lead acid batteries with dry cells. A well-maintained gel or AGM battery can last for up to 7 years.
- Lithium-ion batteries: The battery in an electric automobile has a relatively long lifespan. Electric vehicle batteries, such as lithium ion batteries, often have a 5-8 year warranty but are predicted to last 10-20 years.
- NiMH battery: The nickel-metal hydride (NiMH) battery is primarily employed as a hybrid car battery and has an 8-year lifespan.
The type of battery isn’t the only factor that influences the battery’s longevity, let’s take a look at some more factors that affect battery life.
Other elements that affect batteries’ longevity include
1. The period of time
As the alternator charges it up each time, the battery degrades progressively. As time passes, the capacity of your battery depletes, and it can no longer be fully charged.
The capacity of a battery reduces to 80% after 500-1200 charge-discharge cycles (80 percent is the typical limit defining battery cycle life).
Even so, battery cells do not suddenly quit working.
The battery will degrade at the same rate.
A cell, for example, can hold 80% of its original capacity after 1000 complete cycles. It remains operating until its capacity drops to 60%, which might take up to 2000 cycles. As a result, the likelihood of a sudden battery death is low.
2. Temperature On lead acid batteries, heat has a two-way effect.
It facilitates the chemical reaction that generates energy (which is why starting an engine in warm weather is easier than in cold weather). However, it hastens the deterioration of the battery. So, what happens next?
Hot weather (or even a hot motor) causes battery fluid to evaporate, causing interior cells to be damaged and thus reducing battery life.
Batteries survive about 5 years on average in mild areas, but only 3 years in hotter climes. Some cars have a heat shield on the battery to keep it cool under the hood.
Vibrations caused by vehicle movement can damage internal battery components, causing them to fail. To avoid excessive tremors that can affect battery life, make sure your automobile battery is securely fastened to its mounting.
4. The charging process
When the engine is running, the alternator charges the automobile battery. Problems with the charging system can hasten the battery’s depletion.
Overcharging can result in battery fluid leaks, whilst undercharging hastens battery drainage. Allowing a car battery to totally discharge will reduce its lifespan by a significant amount, even if it can be recharged later.
5. Make use of
When not in use, vehicle batteries are energy storage devices that steadily self-discharge.
Because your car battery charges while you drive, leaving it parked for extended periods of time will reduce its charge. And the more onboard gadgets the automobile has, the faster the battery will drain to sustain them.
Short-distance driving, on the other hand, might put a strain on the vehicle’s battery. The battery charge drains quicker than the charging device can recharge it when you take very short excursions.
What Are The Signs That Your Car Battery Is Failing?
When your car’s battery is on its final legs, it will raise the following red flags:
1. Engine Cranking Times That Are Longer
It’s a solid sign your automobile battery is nearing failure if your engine takes longer than usual to switch over and spark to life. You’ll be lucky if you get a few more cranks before you need to replace the battery.
2. Electrical Issues And Dim Headlights
The starter and all electronics in a vehicle, including the headlights, air conditioning, and onboard computer, are powered by the battery. A low battery will struggle to keep the electronics running at full power, which will be most noticeable in the form of dimming headlights.
3. The Engine Clicks But Doesn’t Start
Let’s assume you put the key in the ignition and all you get is a click or a buzz, but the engine doesn’t start. The headlights and dashboard lights, on the other hand, are in perfect working order.
In this situation, you’ll probably need to use jumper cables, but make sure your battery is charged and tested first. If the issue isn’t with the vehicle’s battery, it’s possible that something else is consuming too much power.
4. The Dashboard Lights That Are Involved With The Battery Are On
The presence of a dashboard battery light or check engine light does not always indicate a failing battery. It could also suggest alternator issues, and the best way to find out is to have your mechanic do a battery test.
5. The Battery Is Defective
The contour of your car’s battery should never be crooked. Extreme temperature changes, on the other hand, might cause the battery casing to bloat, bulge, and crack.
If your vehicle’s battery appears to be distorted in any manner, have it evaluated because the battery’s life may be coming to an end.
How Can I Extend the Life of My Battery?
Here are some things you can do to keep your battery healthy and extend its life:
- To keep your battery charged, drive your automobile on a frequent basis.
- Between long engine starts, use a car battery maintainer (battery tender).
- Corrosion on the vehicle’s battery terminals must be removed.
- Car accessories should not be left on for lengthy periods of time because they consume a lot of power.
- The battery heat shield should not be removed from the car battery.
- Maintain your vehicle’s engine and components on a regular basis to ensure that the battery’s life is extended.
- After an off-road trip, inspect your car batteries for loose cable connections.
