7 Significant Factors that Affect the Car Battery Life

Significant Factors that Affect the Car Battery Life


How long a car battery will survive is a complicated subject, but some generalizations can be made based on decades of industry experience. First, we know three crucial variables—time, heat, and vibration—significantly impact a car battery’s lifespan. Let’s examine each in more detail. These are the factors that significantly affect the car battery life.


Car batteries age with time and have a limited lifespan, just like people. Batteries eventually deteriorate until they cannot supply enough power to start an engine, even under optimum working conditions. Driving habits also influence battery aging. Batteries in cars that are usually used for short excursions may not be able to recharge fully, while batteries in vehicles that are left parked for a long time naturally self-discharge. Using a maintenance charger will maintain the battery ultimately charged and increase its useful life in each of these scenarios.

There are multiple companies that offer services for car battery replacement in Abu Dhabi. You can contact these companies to get your car batteries checked before they expire.


Heat speeds up the chemical process that batteries employ to produce power but also quickens the rate at which batteries deteriorate. A battery may last five years or more in cooler northern regions, while three years is more common in hot southern settings. Additionally, batteries are exposed to a challenging environment under the hood, where temperatures can easily reach 200 degrees Fahrenheit in hot weather. To reduce this heat, automakers may put the battery in a secluded location, cover it with a heat shield, or move it outside the engine compartment, frequently under the back seat or trunk floor.


Vibration, which results in the physical degradation of internal battery components, is the final essential element in battery life. Batteries are held in place and kept from moving around by special hold-down hardware to reduce the impacts of vibration. Battery life can be drastically shortened by missing or sloppy hold-downs. 

Other Major Considerations

These are other factors that affect the car’s battery life. Even though it happens less frequently than the issues mentioned above, a broken charging system will shorten battery life. Consistent under or overcharging hastens the aging of batteries. For maximum battery life, certain more recent automobiles with absorbent glass mat (AGM) batteries need to monitor charging rates carefully. The OEM may even change the charging method as the battery ages. Finally, even though a car battery can be recharged and put back into use, doing so will significantly reduce the battery’s lifespan. 

Warning Signs of a Weak Battery

If the starter motor cranks the engine slowly or the Battery/Charging warning indicator is on, you might have a battery issue. Dim incandescent headlights, especially when the machine is idle, are another sign of a poor battery in older vehicles. But not all battery failures manifest themselves in overt symptoms.

It’s quite obvious that the battery is deteriorating if your automobile won’t start at all. It is feeble and unable to supply enough power to create the car. Numerous problems, such as a dead battery, a damaged alternator, or rusted cables, could be to blame for this. Have a mechanic look at it if you’re not sure what’s wrong.

Has the battery been checked at every oil change to ensure the cable connections are clean and tight and the hold-down hardware is stable to prevent becoming stranded due to a battery issue? Have a battery tested every year when it reaches the age of three? If the battery has degraded to the point where replacement is advised to avoid an unexpected failure, the test will reveal that.  

Your Battery Case is Bulging

Another indication that the battery is dying is if you glance at the battery case and see it bulging. This can result from an overcharged battery or an excess of gas inside. In either case, this isn’t a promising indicator of the condition of your battery. Therefore, you should swap it out right away. A defective cell may also be to blame for a bulging battery case. This indicates that the positive and negative battery plates are in contact with one another, heating them up. The battery’s casing expands as a result of the heat-induced gas accumulation in the cell. If this occurs, you should get your car inspected by a mechanic to see whether the battery can be repaired or whether it needs to be replaced entirely.

Dim Headlights

The fact that your car’s headlights appear much dimmer than they ever did may indicate that the battery is starting to fail. The voltage output of a healthy, fully charged battery will be close to 12.60 volts. However, that voltage output will start to decrease as the battery loses power. The headlights will begin to dim when the voltage falls to roughly 12.40 volts.

Keeping an eye out for any warning signs your car may be trying to give you is essential since a failing car battery is much more likely to leave you stranded. You should take your car to repair as soon as possible if it exhibits any of these signs.

Members can typically call car battery change Abu Dhabi service to have a battery checked out and replaced (if necessary) at their residence or place of employment.

Battery Type

As discussed before, traditional lead-acid batteries or the more modern AGM design are used in batteries. Most vehicles on the road now use conventional batteries. Still, certain models employ AGM batteries, which are far more spill-resistant and better equipped to withstand repeated discharge and recharging, as with vehicles that feature stop-start engine systems to increase fuel efficiency. We advise always replacing a battery with the same kind that was installed in the automobile when it was new because charging methods are frequently tailored for the battery type.


Always get a new battery for your automobile from a high-volume seller with a current inventory. A battery that has already used up a significant amount of its operational life shouldn’t be left unused. A battery with an extended full-replacement warranty is another thing to look for. Quality batteries offer free replacement if there is a problem within three or more years. When the entire coverage term ends, a warranty that enters a prorated replacement period earlier will call for a portion payment to replace the battery.
