What drains the battery of my automobile when it is not in use?
Although it can be inconvenient, a dead car battery can also be prevented. You must first understand what causes a dead battery in order to prevent one. Put the jumper cables away and have a look at these seven potential causes of your car battery dying instead.
You left your headlights on.
The first thing to examine if your car battery continues draining is your lighting. The headlights on many modern cars are programmed to turn off after a particular period of time. However, if your automobile lacks this feature, your headlights can continue to operate either until you turn them off or until your battery is fully depleted.
Something is causing a “parasitic draw.”
The clock, radio, and alarm system all receive electricity from the battery even while the car is not moving. Your battery shouldn’t be significantly impacted by these items. When a car is not in use, factors like interior lights, door lights, or even faulty relays can deplete the battery.
The alternator recharges the battery while your engine is running, so you usually don’t have to worry about it dying while you’re blasting the radio on the way to work! However, while the engine is turned off, the alternator is unable to replenish the battery, allowing minor electrical malfunctions to completely empty your battery. These electrical glitches put stress on the battery, which is referred to as a parasitic drain.
By turning off all of the lights and ensuring that your doors, glove box, and trunk are completely closed and secured before exiting the vehicle, you can help prevent parasitic draws.
Your battery connections are loose or corroded.
Your battery’s positive and negative connections may occasionally become loose over time. Additionally, these terminals could corrode. You can have difficulties starting the car if your connections get loose or corroded since your battery can’t effectively transfer its power! You might even lose control of the vehicle while driving and harm its electronic systems. Cleaning the battery connections on your automobile on a regular basis might aid in preventing corrosion-related issues! Visit your neighborhood Firestone Complete Auto Care and let a qualified technician take care of cleaning your battery terminals if you’re unsure how to do it yourself.
It’s extremely hot or cold outside.
Your car’s battery may experience issues during the chilly winter months and the scorching summer months. Batteries that are more recent typically survive high seasonal temperatures better. Nevertheless, if your battery is older, extreme cold or heat could impair it or possibly kill it. Come to Firestone Complete Auto Care for a free battery check if you notice your battery is struggling to withstand the weather; our auto specialists will assist identify and resolve the problem.
The battery isn’t charging while you drive.
When you start the engine, your car depends on your battery. However, the alternator is what keeps your battery charged while your car is running. Even if you were just traveling, it could be challenging to start your car if your alternator isn’t functioning properly because it can’t charge your battery efficiently.
After driving, if your car still won’t start, it can be your alternator. To find out what the issue might be, bring your automobile to a Firestone Complete Auto Care for a diagnostic examination.
You’re taking too many short drives.
Your battery loses a lot of energy when you start the engine, however as we just explained, the alternator recharges your battery as the engine runs. The alternator may not have enough time to fully recharge your battery between pit breaks if you often take short drives, especially if your battery is older. Over time, making lots of short excursions might reduce the life of your automobile battery.
Your battery is old.
Your car’s battery is one thing that doesn’t last forever. Depending on your driving habits and where you reside, your car’s battery may occasionally last up to five years. Your battery’s lifespan could be reduced to two to three years by extreme temperatures, frequent short excursions, and routine daily use. It might be time for a new battery if your car’s battery dies quickly, even after a jumpstart.
Why keeps going dead my new battery?
It should not be surprising that your car would not start when you try to start it after letting it sit for a few months. A dead battery may be at blame for this. Even if your automobile is brand new or you routinely drive it, you could still experience the same problem. As a result, your only option is to call the closest emergency roadside help provider to resolve the problem.
The issue is, what specifically could be the root cause of your battery’s initial demise? Your car’s battery drain could be caused by a variety of factors. For assistance, get in touch with nearby car-boosting service providers. However, being aware of the actual cause of the issue will help you keep your automobile from breaking down on a chilly Ontario morning. The most frequent causes of a drained battery are listed below.
You Leave Your Headlights On
When you leave work, the only thought on your mind is getting home to unwind after a busy day. Consequently, you neglect to properly close the door before getting out of the car or switch off your headlights. You discover that your battery has died when you go to start the automobile in the morning. This is due to the battery’s ability to recharge all of your car’s electronics after the engine has been turned off. Even a modest dome light can drain your battery, making it impossible for your car to start the next morning. Make sure your battery is charged as an easy solution to this issue.
Something Is Causing A ‘Parasitic Draw’
Your battery may run out due to an accessory that is turned on. But what if your engine won’t start even with all the accessories turned off? This can indicate that your automobile has a bad cable that is draining the battery cover without causing any obvious issues. An example of this is a parasitic draw.
Your battery is charged by the alternator while the automobile is operating, but when it is stopped, the alternator stops. Your automobile can be jumpstarted to resolve this. To fix the damaged wiring and prevent reoccurrence of the issue, get in touch with your neighborhood automobile boosting service.
Loose Battery Connections
If the battery is unplugged, your automobile won’t start. The battery terminals may deteriorate or the connectors may occasionally jiggle loose. Either the battery won’t transmit power fully as a result of this or the engine will completely shut down. You can fix this issue by tightening your connectors. However, corrosion-related issues necessitate routine battery cleaning. By doing this, you can be confident that your battery is fully charged.
Harsh Weather Conditions
Your car’s battery may experience issues in the sweltering heat of the summer and the bitter cold of the winter. Extreme temperature resistance has improved in new batteries. However, sudden temperature changes can sometimes cause even brand-new batteries to fail. The performance will either decline overall or go out of existence as a result.
Contact your local auto repair shop to help you identify and fix the issue if you discover that your battery is having performance problems.
Battery Is Not Charging
If the alternator in your vehicle is not operating properly, you cannot rely on your battery to start the vehicle. An alternator is required to keep your battery charged. Your battery cannot be successfully charged if your alternator isn’t functioning. By changing the diode, a minor component of the alternator, you might be able to save some money. You might need to entirely replace your battery if the issue keeps coming back.
Frequent Short Trips
As your engine runs, the alternator charges the battery. However, if you regularly travel short distances, the alternator won’t have enough time to fully recharge the battery. Long-term, this will reduce the battery’s life expectancy. Longer journeys will enable the battery to charge to its fullest potential.
Things To Keep In Mind
Always remember to lock the car doors and turn off all the car’s accessories before getting out. Regularly inspect your battery connectors to make sure they are not loose. Call a nearby auto repair shop if you continue to have issues with your car’s battery.

- The battery in the phone has reached the end of its useful life.
How long does a battery in an Audi last?
The battery life of an Audi vehicle will differ. Any automotive battery should typically last between three and five years. Although a battery’s lifespan can be extended with proper maintenance, it is typical to need to replace a battery every three years.
Why did my car’s battery fail after a few days of inactivity?
What Reawakens a Dying Car Battery? Loose or corroded battery connections, chronic electrical drains, charging issues, continuously consuming more power than the alternator can supply, and even extreme weather are some of the most typical causes of recurrent automobile battery failures.
How can I determine what is using my battery?
- Launch the Settings program.
- Extend the section on devices or devices’ care
- Press Battery. To determine which apps are consuming the majority of your Android’s battery, you should check while it is relatively low.
- See which applications consume the most battery life by scrolling down.
- To learn more about how long each app was running in the background, tap on each app.
Of course, other factors affect your phone’s battery life as well besides apps. You should be aware of these widespread phone battery myths in order to cease believing them as you work to solve the issue. You should check whether apps are secure in addition to evaluating which ones might be sapping your phone’s power. For instance, if you’ve ever questioned, “Is WhatsApp safe?,” study up on it to ensure that, if you have that program on your phone, your private information is protected.
Dim or Overly Bright Lights
Your electronic gadgets receive erratic voltage when an alternator starts to fail. This typically manifests as under- or over-performing equipment, such as headlights that are either too dim or excessively bright. Additionally, you can see lights that erratically switch from bright to low and vice versa.
Dead Battery
A dead battery may occasionally just be a dead battery. After a few years of use, it has either reached the end of its lifespan or you may have unintentionally kept the headlights on all night. A dead battery may occasionally indicate a problem with your alternator, though.
When the engine is operating, a defective alternator won’t adequately charge the battery, resulting in a quicker than usual discharge of the charge. Jumpstarting the vehicle is one approach to determine if the problem is with the battery or alternator. If your car runs after being jumpstarted, your battery may need to be replaced shortly. If the car dies again soon after being jumpstarted, it may indicate that your alternator isn’t providing enough power to the battery.
Slow or Malfunctioning Accessories
Accessories that operate slowly or not at all are frequently a sign that your alternator isn’t providing enough power to your car’s electronics. You might have an alternator issue if you notice that your windows roll up or down more slowly than usual, if your seat warmers seem “off,” or even if your speedometer and other instruments start acting strangely.
If the alternator isn’t producing enough electricity, many modern cars feature a priority list of equipment that informs the onboard computer where to cut power first. In this manner, if your alternator fails while you’re on the road, your radio or other unnecessary equipment will continue to function before your headlights.
Trouble Starting or Frequent Stalling
As was already noted, if your engine is difficult to start, your alternator may not be charging the battery. As a result, when you turn the key in the ignition, all you’ll hear is a clicking noise rather than your engine’s purring sound.
On the other hand, if your car repeatedly stalls out while you’re driving, it can mean that the alternator isn’t supplying the spark plugs with enough power to keep the engine running.
Growling or Whining Noises
There are many strange noises that cars make; some are harmless, while others may be signs of major technical issues. You should have your alternator checked properly by a professional right away if you ever hear growling or whining sounds coming from underneath the hood.
When the belt that rotates the alternator pulley falls out of alignment or rubs against the pulley’s side, a growling or whining sound is produced. If the bearings that spin the rotor shaft are failing, you can also hear this noise.
Smell of Burning Rubber or Wires
A burning rubber or wire stench could be a sign that your alternator’s components are beginning to wear out. The drive belt for the alternator may eventually wear down and give off a terrible burning rubber odor due to the constant tension and friction it experiences as well as its proximity to the hot engine.
Similar to an electrical fire, your alternator may smell burning if it is overworked or if it has frayed or damaged wiring. Wires in an overworked alternator heat up dangerously as a result of trying to force too much energy through them. In addition to creating resistance to the passage of power, damaged wires often heat up and smell bad.
Battery Warning Light on Dash
When the battery warning light appears on the dashboard, it’s frequently believed to indicate a problem with the battery. The battery warning light, however, suggests that there might be an issue with your car’s larger electrical system, which includes the alternator.
The normal operating voltage for alternators is between 13 and 14.5 volts. The battery warning light on your dash may come on if your alternator is malfunctioning because its voltage may fall below its maximum level. Similarly, depending on how much strain the alternator is under, the battery light may also come on if the alternator is operating above its voltage limit.
The alternator may fluctuate in and out of its intended voltage capacity depending on the electrical demand from your car’s accessories (headlights, wipers, radio, etc.), which might cause the battery warning light to flash on and off. Although it can seem like a minor inconvenience, it’s preferable to have your car inspected for alternators than to become stranded on the side of the road.
