Battery Needs To Be Replaced

EASY FIX! Car Battery Keeps Dying? How to fix in 1 minute

Finally, the last potential reason might be the most obvious: the battery is simply too old to hold a charge anymore.

On average, most car batteries will last about 5 years, but your mileage quite literally may vary. Cars that spend their lives in extreme weather areas with very hot or very cold temperatures will have to replace their batteries much more frequently than in places with mild, dry climates. If you’re not sure if your battery needs to be replaced, head to the Capitol Subaru service center! We can quickly perform a battery health test to determine if your battery has plenty of life left in it, or if a new battery is in order.

Your Battery Terminals Are Corroded

Corrosion between the battery terminal and battery

Look at the corrosion on these battery cables. And you wonder why it wont start?

post creates electrical resistance that prevents your charging system from fully recharging the battery. So, no matter how often you drive or how long you drive, the corrosion reduces the amount of charging the battery receives. Corrosion also puts an extra burden on the alternator, causing it to fail early. Cleaning your battery terminals is the best thing you can do to keep your battery in tip-top shape.

You Drive Short Distances And Your Car Battery Keeps Dying

Every time you start your engine, you drain power from the battery. If you then drive a short distance, the charging system doesnt run long enough to replace all the power lost during the start-up. If you drive a short distance and run any electrical accessories like the heater, defogger, heated seat or headlights, you drain considerably more power out of the car battery. The result is a constantly discharged battery.

Just for reference, it takes at least 30-minutes of highway speed driving to recharge a discharged battery. If you think you can let the engine idle to recharge your battery, think again. It takes almost 4-hours of idling to recharge a dead battery.

Heat Can Hurt Your Phone Battery’s Anode

Remember how moving electricity around causes heat? The anode is the part of the battery that receives new electricity when you charge it.

It’s also where lithium-ion batteries face a particular weakness: anode fracturing.

The anode, receiving new electrons, warms up. Warm things expand. It returns to normal as it cools down. However, the more often the anode expands and contracts, the more likely it is to break.

The warmer your phone gets while charging, the more likely it is for microscopic cracks to form. Anode cracks make it hard to recharge the phone battery completely. The electricity has to find new paths around those cracks. And anode cracks are irreversible.

You’re Taking Too Many Short Drives

Cranking the engine takes a tremendous amount of power from your battery, but as mentioned previously, the alternator recharges your battery while the engine runs. If youre frequently going on short drives, though, the alternator might not have enough time to properly recharge your battery between pit stops especially if you have an older battery. In the long run, frequent short trips can shorten your car batterys lifespan.

Cause #: Faulty Alternator

Car Battery Keeps Dying | Parasitic Draw Test | Car Audio Q& A

Alternators are installed in automobiles to power the electrical system once the engine is turned on. It is driven by the crankshaft through the serpentine belt. Another function of an alternator is that it charges the battery after ignition. If your car has a faulty alternator, then it could drain your battery since it is not charging properly.

Driving short distances is also a cause for draining your battery. An alternator needs some time to charge your car battery after ignition. As such, short trips are bad for your car battery since they will not fully recover. You should leave your car running for at least 10 minutes after a short trip to avoid car battery dies overnight,

An Underpowered Honda Battery Is Subject To Parasitic Drain

There are certain generations of Honda Accords and Honda CR-Vs that chew through batteries. An underpowered battery, parasitic drains, and inefficient battery charging systems will likely prevent one from starting if left for a few days.

Over the years, Honda has published several technical service bulletins describing potential software fixes for battery problems. However, these fixes have been limited to the 2012 and 2017 model years and arent always practical.

Can A Bad Alternator Kill A Good Battery

Bad alternators can absolutely kill a good battery. There are two ways that it can do this.

First, your alternator might not shut off and end up overloading the battery with too much voltage.

Conversely, it might not charge the battery at all. If this happens, youll need to jumpstart your battery multiple times. When this happens, it means your battery voltage is completely drained, and this can end up permanently killing your battery.

Keeping A Car Battery Alive In The Winter And Summer

Anytime your car battery is operated outside the optimum temperature range, the fact is that there is a greater chance it will fail, whether its freezing cold or boiling hot outside. In the winter, one huge thing you can do in the winter is to keep your battery charged. According to Interstate Battery, a weak battery will start to freeze 503 at 32 degrees Fahrenheit, while a fully charged battery wont freeze until about -76 degrees Fahrenheit. Of course, its also a great idea to have your battery load tested, the electrolyte checked, and the connections checked for any signs of corrosion before the winter chill comes around.

In the same way, you can help your battery last longer in the summer with a little preventative maintenance. Since one of the biggest culprits of battery failure is heat, which causes electrolyte evaporation, it never hurts to keep an eye on your electrolyte throughout the warmer months. If the electrolyte starts to drop, then you can top it off before the problem becomes any more serious.

    How To Keep Your Battery From Repeatedly Dying

    While its true that every single battery has to die eventually, the key to prolonging the life of a lead-acid battery like the one in your car is to keep it well maintained and in good working order. If youre dealing with a situation where your battery goes dead over and over, theres a good chance that every time it dies like that, the ultimate lifespan of the battery is shortened.

    By keeping on top of corrosion, making sure that the battery connections are tight and secure, and not allowing the electrolyte in a non-sealed battery to drop, you can actually help your battery last much longer.

    There may not be a lot you can do to avoid other issues, like a sudden parasitic drain, but dealing with that type of problem in a timely manner can also help prolong the life of your battery. A battery tender can also help in the winter if it gets especially cold where you live, or if you dont plan on driving your car for an extended period of time.

    Watch Out For These Red Flags To Avoid Getting Stuck On The Road

    Battery Keep Dying? Simple Tests For A Battery Drain (Parasitic Draw)

    Your battery is one of the most important components of your car. It keeps your vehicle running and powers its electrical components.

    Its wise to make sure that your battery is in good condition at all times to avoid the hassle of having a weak or dead battery at the most inopportune times.

    If youre no stranger to the problem of a constantly dying battery, you might want to find out the reasons for this so you can address the problem head-on. Here are five common reasons why a car battery keeps dying:

  • Headlights left on
  • One of the most common reasons for a dead battery is accidentally leaving the headlights on. The good thing is that this is quite easy to solve. A simple jumpstart can bring your battery back to life.

  • Parasitic drain
  • This means something in your car is draining your battery even when its not in use. The most likely culprits are your cars clock and audio system. The battery drain could also be caused by a malfunctioning trunk light or a problem with your cars wiring.

  • Malfunctioning alternator
  • Your alternator recharges your battery. If your alternator is broken, it will not charge your battery after it uses a lot of energy to start your car. If it does not charge, your battery will weaken and eventually die.

  • Corroded battery terminals
  • Once your battery reaches the end of its life cycle, it will die and never come back no matter how many jumpstarts you do. If you dont recharge your battery regularly, this will come sooner than later.

    Cause #: Parasitic Drain

    Parasitic drain is another common cause of why a car battery died overnight. What it does is continues to discharge the battery even after shutting the engine off.

    Your car battery is still powering some components once the engine is turned off such as the clock and anti-theft features. Parasitic drain occurs when it sends to other components that shouldnt be charged after the engine is turned off.

    This can be a result of various factors including the number one cause which is leaving headlights, glove box lights, or cabin lights on overnight. Parasitic drain can also be caused by defective fuses, bad wiring, and poor installation of a new car battery.

    Does Jump Starting Another Car Drain A Battery

    Yes, jump starting another car draws significant power from your battery.

    This power drain is usually recharged through the alternator during driving. However, the battery may require an additional charge to recover fully.

    Dont have jumper cables?

    The differences are in the needs of the car. Premium batteries tend to hold more charge and have longer battery life. While premium batteries are common in new vehicle models, the traditional lead acid battery is still used in most cars on the road today.

    Its best to know your cars energy requirements before buying a new car battery.

    What To Do If You Have A Parasitic Draw

    If you do have a parasitic draw, you need to isolate the circuit that is drawing power. The easiest way to do this is to keep your multimeter hooked up to the parasitic draw test while pulling fuses.

    Simply pull one fuse at a time and watch to see what the multimeter does. If you see the amperage drop significantly, youve found a source for the parasitic draw. If your amperage doesnt drop, reinsert the fuse before pulling the next one.

    If you pull a fuse and the amperage drops, but its still not under the 100mA threshold, you have multiple parasitic draws. Youll need to find out what is causing all of them to keep your battery from dying!

    Once youve isolated the circuit, you can cross-reference what circuit runs through that fuse. Sometimes multiple circuits will run through a single fuse, and youll need to unplug specific components to find out what exactly is causing the draw.

    What you need to do to fix the problem will vary widely depending on what circuit is creating a draw. Still, now you have a starting point!

    Battery Is Not Charging

    Dead Car Battery? Here

    You cant rely on your battery to start your engine if its alternator is not functioning properly. Your battery needs an alternator to keep it charged up. If your alternator isnt working, it cant power your battery effectively. You might be able to save some money by replacing a small part of the alternator called the diode. But if the problem continues to resurface then you might have to replace your battery completely.

    Something Is Causing A Parasitic Draw

    Even while your car is off, your battery provides power to things like the clock, the radio, and the alarm system. These things shouldn’t have a major impact on your battery. What may drain a car battery when it’s off are things such as interior lights, door lights, or even bad relays.

    While your engine runs, the alternator recharges the battery which is why you typically don’t have to worry about the battery dying while you’re blasting the radio on your drive to work! But when the engine is off, the alternator can’t recharge the battery, allowing little electrical mishaps to drain your battery entirely. The battery strain caused by these electrical whoopsies is known as a parasitic draw.

    You can help avoid parasitic draws by turning off every light and making sure your trunk, glove box, and doors are fully closed and latched before leaving the car.
