How to Charge Your Car Battery with a NOCO Battery Charger

Picture this: you're driving down the highway on a cold, dark evening, when all of a sudden, your car stops running. You desperately try to turn the key on your ignition repeatedly, to no avail. That's when it hits you:

Your car battery has died.

Now you're probably thinking, "No way this could ever happen to me!" But this kind of scenario happens more often than people realize. 

A dead car battery is enough to ruin any plans you may have, whether you're going on a road trip, heading to an important meeting, or attending a family emergency.

That's why it's imperative to always have the right tools whenever you're driving. In this case, it's having a car battery charger at all times in your vehicle.

Let's look at the many reasons why a car battery could fail, how to remedy this situation, and why a car battery charger like the NOCO Genius 5 might be the perfect all-in-one solution for your needs.

Let's dive right in!

What Causes Batteries to Fail Prematurely?

A good car battery usually lasts several years, but certain factors such as the ones below can greatly contribute to premature battery failure.

Alternator Problems

An alternator is the part of your vehicle's electrical system that generates electricity to recharge the battery. 

According to East Coast Toyota, alternator problems can lead to battery drain, and one of the most common of these is diode failure due to either overheating or age.

If one or more diodes in the alternator fail, it can cause the alternator to produce less electricity or lead to a complete failure. You might notice dimming lights or electrical issues when the engine is running. 

Here are some other common alternator issues:

• A worn or loose drive belt can impede an alternator’s proper functioning and lead to insufficient power generation. You might hear a squealing noise from the engine compartment.
• Voltage regulator failure can lead to overcharging or undercharging of the car battery. You may notice flickering dashboard lights, an illuminated battery warning light, or a dead battery.

Parasitic Draw

Parasitic draw refers to the unintended, continuous consumption of electrical current from a car's battery while your vehicle is turned off. 

Some causes of parasitic draw include:

• Interior lights, trunk lights, glove compartment lights, and other lights that stay on after the car is turned off
• Alarms, GPS trackers, audio systems, phone chargers, and other electrical accessories that continue to draw power
• Malfunctioning electrical components or wiring, such as a short circuit or a defective relay
• Control modules that do not enter sleep mode or fail to shut off properly after the vehicle is turned off

Corrosion

According to Firestone, the terminals on your battery can sometimes get corroded and can loosen over time. 

Corrosion can be caused by chemicals and gases from the battery interacting with the conductive metals of the battery cables. This then obstructs the flow of power from the battery and makes it hard to start your car. 

To prevent corrosion on your battery, you can invest in a high-quality battery protection product like the NOCO NCP2 Battery Corrosion Preventative. This will help create a protective barrier on your battery terminals and connectors.

Extreme Temperatures 

According to Kia, both scorching and freezing temperatures can cause lead sulfate crystals to accumulate on a car battery’s lead plates. This buildup is also called sulfation.

Sulfation reduces your battery’s capacity to hold a charge, makes it harder for your vehicle to start, increases battery charging times, and eventually leads to premature battery failure.

Age 

According to Autodeal, 

“Regular batteries, the ones that you buy from a battery store can last anywhere from 3 to 5 years depending on certain criteria. These usually revolve around hot or cold temperatures, increased electrical use, driving time, and alternator and drive belt condition. If these are consistent and if the alternator and drive belts are always in good shape then your battery should be able to maximize its intended lifespan.” 

If a relatively new battery fails, it may be due to a manufacturer defect, and checking warranties may provide solutions.

Why You Need a Quality Car Battery Charger

Prevent Battery Failures

Car batteries can fail for various reasons and having a reliable battery charger on hand can help you avoid them. 

As mentioned earlier, common causes of a dead car battery include cold weather, which can drain a battery’s power, and extended periods of inactivity where the car isn’t used enough to recharge itself. 

Parasitic drains, such as leaving your lights on or using electronic devices while the car is off, can also sap your battery’s charge.

A high-quality charger like the NOCO GENIUS5 is designed to address these issues. It delivers the right amount of power needed to recharge your battery safely, helping you avoid the headaches of a dead car. 

By keeping your battery charged and ready, you can reduce the likelihood of unexpected failures and improve the overall reliability of your vehicle.
