How Long Can a Car Battery Last? 5 Answers You Need Right Now

by

When was the last time you drove your car?

For most of us, that question would have been comical a few short months ago. But moving past a month of stay in place, that question now may take some thought. A week ago? A month ago?

Your wallet may be thanking you for not spending a lot on gas these days. But if you don’t pay attention to caring for your car the proper way right now, you may pay for that as we come out of lockdown. Cars are meant to be driven. The more they sit, the more problems can arise.

Which is why we’ve put together a series of questions and answers about one of the first things that can happen to your vehicle the longer it sits: problems with your car battery.

How long can a car sit before a car battery dies?

A car battery isn’t like a battery you put into your phone or your remote control. It isn’t fully charged, dropping down ever so slowly as it sits or is used.

Instead, a car battery is typically a lead acid cell battery made up of 6x 2V cells or piles. A lead acid battery is bigger and heavier than other batteries, and is designed to produce high current over short durations. Alkaline batteries produce low current over longer durations, and are in general safer even when leaking, as they won’t eat through what’s around it the way the sulfuric acid from a lead acid battery will.How Long Can a Car Battery Last? 5 Answers You Need Right Now

With this set up, a car battery is designed for short spurts of energy. It’s designed to jolt the car engine to life as the key is turned or button is pushed. This charges the alternator, which is what continually powers a variety of things in your car, such as the lights or radio.

To stay in good function, the car battery needs that jolt periodically to recharge the cells. Without it, the power continues to drain until the battery no longer works.

How long a car can sit before the car battery dies depends on a variety of things:

  • How old the battery is
  • Under what circumstances the car battery has been used
  • Temperatures and road conditions
  • The make and model of the battery
  • Driving conditions

Predicting how long a car battery will last if it isn’t used is difficult at best. A month? Two months? Longer?

Your best takeaway is to realize the importance of operating your car regularly, even when you’re staying in place.

How do you change a car battery without losing your settings?

What’s one of the most frustrating things that can happen when you replace a battery? Having all of your presets disappear. And in today’s modern cars, that can be a wide variety of details.

That’s why it pays to watch your battery carefully, and change it for a new one long before it dies and leaves you stranded. If you replace a battery while it’s still holding a charge, you can do so and keep all of your presets in place.

To do so, you’ll need a secondary power source. You can use a secondary battery, or a jumper/booster pack. After attaching the secondary battery to your car, you can disconnect and replace the main battery. This will hold the charge in place during the process. With the new power supply in place, test the system and make sure it’s working.

You can also attach a memory saver, which is a small device you can plug in that will provide just enough power to hold your presets in place while the battery is changed.

How long can you play the radio before the car battery dies?

Have you ever sat with the engine off and the radio on, listening to your favorite tunes? Of course. We’ve all done it.

Did you know that’s one of the heaviest drains on your car battery?

How long you can play depends on a variety of things. How old your battery is. Temperatures. The power of your radio.

We Googled this question to find out what some of the answers were, and had to laugh. Some were very specific – how would anyone know you can get exactly 125 minutes of radio time before your car dies? The general consensus is: it depends.

Is your radio standard equipment? Does your radio have a digital screen – this will require more power from the battery.

The bottom line is, if you aren’t using your car regularly, find another way to play your tunes. Keep all listening to a minimum if you aren’t operating your car.

How do you reconnect a car battery safely?

If your car battery is dead, you’ll have to replace it. For safety’s sake, remember that this is an electrical device. “Dead” isn’t really dead, and it can still be harmful – fatal – if not handled properly.

Even if a car battery is dead, you should never let any metal object touch both the negative and positive posts on the battery at the same time. This can cause a current to spark, even to explode.

When removing a battery, identify the positive and negative posts – the positive will have a red plastic cover, while the negative will have black markings. Remove the black/negative cable first, followed by the red. When you reattach, reverse the order – attach the red first, followed by the black. It’s always in this order for safety.

Remove the battery carefully to ensure you don’t spill acid from the battery. They can weigh between 40 and 60 pounds.

Clean all the connections before you insert the new battery. Then reinstall the cables, red/positive before black/negative. Carefully double check all connections and ensure the battery is secure.

Of course, to ensure this process runs smoothly, we recommend never doing this as a DIY project unless you have been trained in auto mechanics. Because you’re dealing with dangerous chemicals and electrical current, it’s important to know what you’re doing before you try it.

What else happens to the car if the battery dies and isn’t replaced right away?

Car batteries die for a variety of reasons. And in some cases, it might not have to be replaced right away.

When you jump a car battery, be sure to keep it running for 10 to 15 minutes to ensure it regains its charge. Don’t take it far from home; remain in a location where you can have access to another jump if you need it.

If it holds its charge, you should have nothing to worry about. If it needs a second charge, it’s time to replace the battery.

The key to good car maintenance is being aware. Watch for signs. Evaluate how well your car is working.

How long a car battery lasts is all about knowledge. Knowing how old your battery is, the conditions it’s operated in, and how well it’s been treated since it was installed.

How Do You Know If Your Car Battery Is Dead?

by

There’s never a good time for a problem with your car, is there? Yet it always seems to happen at the worst time. Maybe you’re running late for a meeting, or picking up the kids. Or perhaps it happens on the coldest day of the year.

Then you’re left stranded, wondering what to do. And trying to think if there was a clue somewhere, telling you something is wrong.

That can happen easily if something is wrong with your vehicle’s battery. How do you know if your car battery is dead?

The car battery 

How Do You Know If Your Car Battery Is Dead?Like tires, car batteries are one of the most recognizable parts on your vehicle. That’s because you can find them almost anywhere, even on the shelves of your favorite membership stores.

A car’s battery is designed to provide electrical current to the motor. It feeds the starter, which in turn starts the engine. Once the car is running, power is continuously recharged through the alternator.

Today’s car batteries haven’t changed all that much since they were first introduced decades ago. Unless you have an electric car, hybrid, or another special performance vehicle, you have a “wet cell” battery installed underneath the hood. This is a plastic cube filled with sulfuric acid and lead. It has two terminals on the top or side, depending on the way it was installed.

Most car batteries on the market today are designed to last about five years. Of course, that number is entirely dependent on the way you drive. A driver that spends a lot of time driving in cold arctic air is going to have different results than someone who spends most of their time driving in the desert. It also depends on use. A city driver who turns their cars on and off all day long will have different results than someone who rarely takes their car out of the garage.

In your car, the battery ranks up there with one of the most common parts that fail. Luckily, it’s also one of the least expensive parts you have to replace.

Signs your car battery is dying

Think of your battery as the heart of the car. If you want to have a reliable car, there for you when you need it, the battery has to be working well.

And like other parts on your vehicle, the battery rarely dies without a few warning signs. Paying attention can help you avoid being stranded with a dead battery. Here’s what to look for.

The car battery signal on your dashboard

This is the easiest, and most apparent. When lights come on your dashboard, pay attention to them. They are designed to give you ample time to bring your car in for service.

The engine cranks, but won’t start

Have you ever turned the key, you can hear your car engine trying to start, but as it turns over, it just won’t catch? That’s a sign your battery is dying. Occasionally, it can be one of several other problems with the starting system, such as your starter. But in almost all cases, it’s about the quality of your battery.

Because your car still has power, it’s just not catching, this is a time you can use jumper cables to start your engine. Once your car is running, let it operate for at least 30 minutes to allow your alternator to charge the battery fully again. Then turn off your vehicle and let it sit for a few minutes. Start it. Start it again. If it turns over, you’re okay to continue driving it.

In a lot of cases, this charge is enough to keep your battery running for a while. But don’t be fooled into thinking your battery is back to normal. Instead, consider this to be time for getting into the service station and replacing your battery.

Your car battery works one day, not the next

If your battery isn’t that old, and your car seems fine one day, won’t work the next, it might be the connections. If the car battery terminals are loose, broken, or corroded, it can cause a problem with the power being supplied to the rest of your vehicle.

Check the battery cables first. This is usually the cause of the problem. Check to ensure they are connected and haven’t wiggled loose. You can also look at the cables and ensure they are in good condition, aren’t frayed, or show evidence of leaks. If you see any problems, it’s time to bring your car in and let one of our mechanics take a look at it.

The car won’t start, no crank, no lights

If your car is completely dead, it’s easy to diagnose: your car battery is at fault. Your battery’s job is to power all of the accessories in your vehicle. If your car won’t turn over, and lights won’t illuminate, it’s a sign your battery is no longer supplying power.

Be aware that if your battery doesn’t even have the power to supply energy to the lights, you might have a bigger problem than just your batter. It might also be a problem with the alternator. The best way to tell what’s wrong is to bring your vehicle into our service station and let us diagnose what’s wrong.

The size of the battery is wrong

Because car batteries are available just about everywhere, they are an easy DIY project, especially for people attempting to save a little money. Do you have a new-to-you car you’ve recently purchased, and are starting to have problems with the car starting? It could be the wrong battery was installed.

You’ve jumped your battery more than once

If your battery dies and you jump it to bring it back to life, it’s your vehicle’s way of telling you a problem might exist. Of course, you might have a lot of life left. But it would help if you watched closely for other symptoms.

If you have to jump your car more than once, and the episodes get closer together, you can no longer ignore the warning signs. Your battery is failing, and if you keep ignoring it, it could fail at an inopportune time. Like on a cold, dark night, when nobody is around.

Is it time to replace your battery?

Manufacturers will tell you a car battery has an expected life of five years. Depending on your driving conditions, two to three years may be the maximum life.

As you near the end of life, watch for little signs that tell you your battery is failing. Bring it in and let us inspect it. We can help ensure your car is working correctly, keeping you safe and on the road without a problem.

Car BatteriesBatteries are a huge part of modern life in Denver and across the country.  I mean, how many battery chargers do you own?

But our purpose here is to talk about your car battery.  When people come into our Denver service center and need a new battery, they’re really not that happy about having to spend the money.  But the fact is that 70 percent of batteries don’t last four years.

There are some things that you can do to extend the life of your battery.  First, keep it clean.  If you see it getting dirty or greasy, let us know at Express Car Care and we can clean it off.  A dirty battery runs hotter and that shortens its life.  If your battery terminals are corroded, let us take a look at that too.  We can clean them, and if the corrosion has gotten into the battery cables, we can replace them.

Also running your battery way down is not good for it:  Things like running the headlights or watching a DVD player when the car is turned off can deeply deplete car batteries.  The typical battery can only take about 10 of those deep cycle depletions before it gives up the ghost.

Because we often take short trips around town with lots of stops for errands, our batteries can end up not getting fully recharged just by driving around.  That also shortens battery life.  You can hook up a good quality automatic battery charger at home from time to time.  We recommend charging once a month during hot months and every three months during cold months.

Now when it’s finally time to get a new battery, we can help you find the right replacement.  We’ll always make sure to meet your manufacturer’s recommendations.  And if you have special needs – like living in a very cold climate or running a lot of electrical accessories, we can look at an upgrade that will give you the power you need.

Summer Heat Can Take Its Toll On Your Car Battery

Summer Heat Can Take Its Toll On Your Car Battery

The 90 degree days are back once again. When your car sits outside all day in the baking sun, if the battery was weak to begin with, you may find yourself stranded with a car that simply won’t start.

One of the most basic parts to your car is your battery. Yet its also one of the easiest things to assume “out of sight, out of mind”. If it works, why worry about it?

Excessive heat shortens the life of a battery. Heat causes battery fluid to evaporate, which then will damage the internal structure of the battery. And when the components of the charging system start to malfunction, it could allow an excessive charge rate, which eventually destroys the battery all together.

To get the most out of a battery:

  • Be sure your electrical system is charging at the correct rate. Overcharging your battery can damage the internal components, weaken the system, and damage the battery until the point of non-function.
  • Always replace a battery with the same or higher quality than the one you are currently operating with. Look for one that has a CCA (cold cranking amps) rating at least as high as your current battery.
  • Always keep the top of the battery and the battery terminals clean. Dirt and corrosion can accumulate, which will inhibit current flow.
  • Check your car’s battery and belts on a regular basis, and replace when they show wear or are cracked.

Don’t put off your car’s maintenance schedule. If you keep up with regular maintenance on a regular basis, you’ll have a car you can depend on at any time of the year.
