Sings My Battery Is Beginning To Run Low

How long should a car battery last?

Even with routine maintenance and proper car battery care, your battery will eventually reach a point where it can no longer generate the power you require. If you aren’t sure how old your battery is or how many miles it’s faced, there are other key signs to look out for that suggest a change is needed.

To identify one of the most common signs, you merely need to pop open your hood and visually inspect the battery. If the battery is leaking any kind of fluid or shows a build-up of corrosion from excessive wear and tear, a change may be in order.

Another aspect to keep an eye out for is starting your vehicle. Batteries are key to jumpstarting any car as you turn the key. So, if you find that your vehicle is having trouble getting started due to some sort of delay or insufficient jump while turning the key, you can often look to the car battery for answers.

Even if you have your vehicle running, any wavering electrical processes can be traced back to the efficiency and overall state of your battery. Dwindling headlight illumination, sporadic flickering of lights along your dashboard, and other electrical malfunctions may suggest that your battery is beginning to wear down and needs to be inspected or replaced!

Figuring Out Your Own Numbers

Battery longevity and performance are measured in controlled environments to get comparable results between various tests. However, driving in the real world comes with a lot of variables.

Before relying too much on official numbers, consider your driving habits, the distance you drive regularly, and how well you take care of your Tesla batteries.

Leaving Your Battery Fully Charged When At Rest

When your engine isn’t running, it’s best to let your battery remain fully charged. That means you should avoid leaving your interior or exterior lights on or playing the radio as much as possible when your car isn’t running. Before you exit your vehicle, always double-check to make sure that your accessories and lights are off. You should also make sure you unplug any adapters, such as cell phone chargers, as using the USB and power outlets can rapidly drain a battery.

Not All Batteries Are Created Equal

Car Battery Life: How to Make It Last Longer

All batteries likes the ones in your TV remote or cellphone have an effective lifespan, after which they need to be replaced. Its no different with the battery in your car.

Some owners of new cars across many makes and models say that the factory-supplied battery may disappoint with a shorter-than-expected lifespan. Eventually, some owners replace the factory-equipment battery with a different battery from a brand theyre familiar with and see improved results. In other cases, a factory-equipment battery may last for years with little issue.

Of course, not all car batteries are made the same way, which is why its important to choose a suitable one from a reputable brand when its time to replace yours. This is the first of several steps that drivers can take to help ensure a long and trouble-free life from the battery in their vehicle, and can make the difference between a battery lasting two years or five years or even longer.


After determining which style of replacement battery is right for your car, consider the warranty offered on the replacement battery youre looking at. Some are pro-rated, while some are longer than others, and some include perks like roadside assistance. There are a multitude of options to cater to every need and budget.

Being Overzealous With Rapid Charging

You may be concerned about the batterys health, so you pull it from the vehicle. Charging car batteries on external systems is commonplace for many vehicle enthusiasts. Place the battery on a rapid charger, and you have full power in no time.

Rapid charging creates issues, however. You might be reducing the batterys lifespan. These products are designed for slow charges so that no overcharging occurs. Battery damage is possible with too much power all at once.

How Much Does An Electric Car Battery Cost

The aforementioned fears are understandable: the battery pack of an EV is by far the most expensive part of the vehicle and can cost $5,000 on average and even as much as $15,000 per battery in some cases.

Its important to note here that battery prices have fallen dramatically over the past decade. For example, the average price of a kilowatt-hourthe standard measure of a batterys pricedropped from $1,160 per kWh in 2010 to just $137 in the past year.

That price is expected to fall to below $100 within three years universally considered the point that EVs will cost as much as gasoline cars to manufacture.

The majority of manufacturers give between five to ten years warranty on their batteries or up to 100,000 kms .

Batteries are designed not to die fully, but slowly lose charging capacity over time. This depletion happens gradually with many reporting the loss of a few percentage points over the several years. To put this into perspective, according to Plug In America, a Tesla Model Ss battery only loses five percent of its original capacity over the first 80,000 km .

However, as with many components of older vehicles, the battery will eventually begin to degrade. To measure this, when looking at the average decline across all vehicles, the loss is arguably minor, at 2.3 percent per year. This means that if you purchase an EV today with a 240 km range, youll have only lost about 27 km of accessible range after five years.

The Toyota Prius has now been part of the world for more than twenty years. And in that time, its gone a symbol of celebutante virtue-signaling to a fine automobile driven by millions. That popularity now means there are old Priuses, which begs the question, whats the lifespan of a Toyota Prius Battery?

Unfortunately, thats not an easy question to answer. Theres a great deal of disagreement concerning the lifespan of any hybrid cars battery due to its relative newness. There is, of course, a manufacturers expiration date similar to those used for most parts on a car. But those are far more conservative given companies dont yet have a mass of consumer data and real-world findings to back anything up.

There is a Toyota-authorized expiration date, but there are also a few things that can affect the lifespan of your Prius battery too that can either decrease or increase that figure. To go over those variables, The Drives eco-vigilante editors put together this comprehensive guide about the Prius hybrid system and how long it lasts.

Driving Time As An Influencing Factor

A strong influence on car battery life involves drive times. You want to prolong the batterys life, so you think about driving long distances instead of short trips. This strategy is technically correct because car batteries rely on charging from the alternator as the vehicle moves down the road.

The problem resides in the length of time that youd have to drive each time. Fully charge a battery after running the car for eight hours straight. Most people dont have these kinds of commutes, which leads to less life out of the battery.

What Is A Car Battery Group Number

The group number, for example Group 24, is an industry standard that defines the battery’s physical size, its hold down configuration, and the type of terminals and their location. Selecting a battery with the same group number as the original equipment battery will ensure a secure fit, adequate clearance, and no cable/terminal issues. It will also allow for proper reinstallation of the important battery heat shield, if your vehicle has one. Some imported vehicles use batteries that conform to European or Asian battery standards. In many cases, a standard group number battery will fit with minor or no modifications, but pay special attention to ensure that the installation does not pose any problems. Refer to the application guide available where you purchase the battery. If you prefer, trust aAAA car battery service tech to install the correct part.

In a limited number of cars, the vehicle design makes a factory replacement battery the only possible option.

Where You Live Affects Your Car Battery

Heat facilitates the chemical reaction car batteries use to generate electricity, but it also increases the rate of battery degradation. In cooler northern climates, a battery may last five years or longer, but in hot southern locales, a car battery will typically last approximately three years.

Batteries reside in a harsh under-the-hood environment where temperatures can easily exceed 200 degrees Fahrenheit in hot weather. To combat this heat, automakers may mount the battery in an isolated area, install a heat shield over the battery, or relocate the battery outside the engine compartment, often under the back seat or trunk floor.

Tips For Making Your Car Battery Last Longer

You can keep your battery healthy with some simple tips. So how long do car batteries usually last with constant care. Well, they will endure years of use and give your moneys worth by using the following tips.

  • Take your battery to a mechanic for annual tests and cleaning. If you want to get a new one, invest in a model that has the same power as the one that came with the vehicle.
  • If you use bad roads or dirt trails, perform checks on the battery cables. Then find any loose connections, tighten them to enhance the battery lifespan. Since rough roads have bumps, they can move the battery around and weaken the connection.
  • When charging a battery, do not use until its full. Avoid using any electronic devices in the vehicle, especially in a parked car. If you ignore this step, the battery becomes weak while the alternator works harder, thereby damaging both items.
  • Check your battery with a battery tester to avoid unexpected failure. You can perform this test at the same time that you change your engine oil.
  • If you stay in a location with low temperatures, your car battery might not last as expected. But if you park in a heated garage and drive less in such areas, you can increase the life cycle of the unit.

The Newer Your Car The Bigger The Strain On Its Battery

As a general rule, the more sophisticated your cars on-board computers are, the bigger the strain on its battery. Many new cars have powerful computers that are operating all the time, even when the vehicle itself is parked and switched off.

These computers can draw energy from your cars battery at a slow, steady rate, wearing it down over time. Although the charge each computer draws is tiny, the aggregate effect can drain your cars battery when it sits unused for a long time.

If you use your car infrequently, avoid letting its battery become drained by on-board computer systems by taking it for a short drive around the block once or twice will do to recharge its battery every week or two.

Why Do Car Batteries Die

Car batteries are designed for one purpose provide a powerful, quick, high-amperage current to the starter to start the car, and then constantly have this charge of 12.4 volts maintained by the alternator once the car is running. The following things, however, can cause a battery to either not retain that charge, or not supply the proper current to start the car.

How Many Years Does The Battery Last

Your individual driving habits will affect the lifespan of an EVs battery, but most manufacturers cover their battery packs for at least eight years, and anywhere from 10,000 to 100,000 miles. Tesla and Hyundai cover their EV batteries for life. Read the fine print here, thoughsome manufacturers will only replace the battery in the event of complete failure, which is exceedingly rare.

So how long can you drive an EV before the battery starts to lose charge capacity? It varies by manufacturer and use conditions, but its usually a very gradual process. EV advocacy group Plug In America collects data from EV drivers on changes in charge capacity over time and found that Tesla Model S vehicles usually only lose around 5% of their total charge capacity after the first 50,000 miles of driving.

The bottom line? MyEV says that, when properly cared for, an EVs battery should get you well past the 100,000-mile mark before its capacity is limited. Some estimates range as high as 200,000 miles. When driven around 12,000 miles per year, thats around 17 years before the battery needs to be replaced. Thats somewhat less than the average mileage of 15,000 per year logged by drivers in North America but still promising.


Conversely, steps like only charging the battery when necessary and staying between 20-80% capacity will help extend the life of an EVs battery pack, according to EVBox.

How To Tell If A Car Battery Is Bad: Slow Engine Crank

Unfortunately, there arent always visible signs your car battery is dying, so its important to pay attention to any sign of trouble when you attempt to start your car. If youre having trouble getting the car to start in the morning and its not a particularly cold day, thats a sign that you almost certainly have a battery problem. A weak or dying battery might make the car sound like its struggling to start up.

Also, if you cant get any lights to turn on fully in the car when you turn the key, the battery is almost surely the culprit.

Even if the car ends up starting after a few cranks, you dont want to push your luck. One instance means that its time to start checking around to see how much car batteries cost and planning your budget appropriately. A second instance within a short time frame means that your waiting period has expired. When that happens, you need to test or replace your battery as soon as possible.

Mechanics measure the power of a car battery in cold cranking amps. A new car battery might start at 650 cold cranking amps, and start to struggle when it dips into the 400s.

The last thing you want to have happen when youre trying to figure out when to replace a car battery is to discover that you waited too long to replace the battery and youre stranded with a car that wont start.
