How Long Does a Car Battery Last?

How Long Does A Car Battery Last

This is a whole guide on a car battery life, here we reveal how long does a car battery last. There is no simplistic answer, but supported by decades of industry background, we all know that three key factors affect the lifetime of a car battery: time, heat, and vibration. Batteries gradually deteriorate until they do not provide enough power to start an engine.

This corrosion time could take three to 5 years, and a vehicle’s practice pattern is one factor contributing to the speed at which a battery will age. Batteries in cars driven wholly on short trips might not entirely recharge and batteries in vehicles parked for extended periods naturally self-discharge.

How Long Does a Car Battery Run – Main Points

Where you live Affects Your Car Battery

Heat facilitates the reaction car batteries use to get electricity, but it also increases the speed of battery degradation. In colder northern ranges, a battery may last 5 years or longer, but in hot southern locales, an automobile battery will typically last approximately three years.

Batteries remain during harsh under-the-hood conditions where temperatures can easily exceed 200 degrees Fahrenheit in the weather. To combat this heat, automakers may mount the battery in an isolated area, install a protective covering over the battery, or relocate the battery outside the engine compartment, often under the rear seat or trunk floor.

Hold down Hardware Prevents Excessive Vibration

Vibration causes internal battery parts to interrupt down. To attenuate vibration effects, use special hold-down hardware to secure the battery in situ and stop it from moving. Missing or loose hold-down hardware can significantly reduce battery life.

Malfunctioning Charging System Reduces Car Battery Life

While less common than the factors mentioned earlier, a malfunctioning charging system also will reduce battery life. Persistent under- or over-charging accelerates battery aging. Some newer cars with absorbent glass mat (AGM) batteries require careful control of charging rates for max battery life. Therefore the automaker may even remodel the charging policy because of the battery ages.

Weak Battery Warning Signs

You may have a battery problem if the starter cranks the engine slowly or the Battery/Charging warning lamp illuminates on the dashboard. In more past models, dim incandescent headlights, notably when the car is idling, shows a weak battery.

Not every failing battery shows itself through obvious symptoms so take anticipations to avoid a dead battery situation. Inspect the automobile battery at every car care. Confirm the cable connections are clean and tight, and therefore the hold-down hardware is secure. Once A battery inserts its third year, have it examined annually. An automobile battery test identifies the deterioration level, so you recognize when it’s time to put in a replacement battery. The knowledgeable service tech will come to your location, conduct a free diagnostic assay of your car’s battery and starting and charging systems, and if needed, install a replacement battery on the spot.

Car Batteries are not one-size-fits-all.

You must consider the battery type, physical size, terminal configuration, and cold cranking amps (CCA) or amp-hour (Ah) rating to make sure you get an automobile battery that properly fits and functions for your make and model vehicle. Installing an unreliable battery can adversely affect the car’s electrical system and cause important damage if the terminal locations found a short circuit with nearby components.

Install the Correct Replacement Battery

Batteries are either approved lead-acid or the more advanced AGM design beginning mentioned. Most cars on the road today use standard batteries, and some models use AGM batteries. These batteries are extremely spilled resistant and better ready to manage repeated discharging and recharging, as occurs in cars that have stop-start engine systems to enhance fuel economy.

How to Improve Car Battery’s Life

If you think that you’re replacing your battery too often, there are some ways to assist extend its lifespan. Because several of the factors depend upon your driving technique, a couple of changes can assist you to prepare the foremost out of your next battery purchase.

First, consider your driving conditions. If you’re continually driving on backroads and bumpy dirt trails, your battery might be affected by a poor connection. Poor connections are inefficient ways to conduct electricity, so merely tightening your battery cable connections and therefore the battery hold-down clamp may help improve your battery life.

Automotive batteries are like all other sorts of rechargeable batteries; it is best to go away from them fully charged when at rest. Avoid playing the stereo or leaving the lights on for an extended amount of your time when the engine isn’t running. This might weaken your battery and cause the alternator to figure harder, decreasing the lifespan of both components.

An easy thanks to remembering to see your battery periodically is to check it whenever you modify your oil. If you change your oil, view investing during a battery tester for timely check-ups, or stop by your local Zone for a free battery test. For car purchasers who’d instead take their vehicle to their granted mechanic, ask them to incorporate a battery test in your car care cycle. This provides you with the right wake-up call if there are any issues together with your battery holding a charge or that it’s going to be weakening.

While you’ll not be ready to avoid driving in cold temperatures, you’ll factor that in once you consider the lifespan of your battery. For drivers in different northern climates, you’ll not be able to get the whole five or more-year lifespan out of your new battery. However, keeping your vehicle in a heated garage and minimizing trips in frigid temperatures could help improve its lifespan.


When you last time changed your car’s battery? Whether your vehicle works like new or, its lights and other electronic devices are beginning to show signs of age, and there’s no wrong time to see your battery’s condition.

Changing your car’s battery every 2-3 years will keep it running at its best and assist you to avoid embarrassing roadside or parking lot breakdowns. Regardless of how well you maintain your automobile battery, you cannot always foresee when it’s going to die.
