How Long Does It Take To Charge a Car Battery

There may be instances that your car’s battery got discharged because you haven’t used it for a long time. You may have accidentally left a light on which caused your car battery to drain.

​I purchased both a portable jump starter and a car battery charger. It is better to have these tools for emergency purposes.

 Also, someone might be in need of them and I could lend them a helping hand. In fact, I bought a car battery charger for my wife, too, and taught her how to use it. I also recommend to my customers to get one, especially when they have cars that they don’t use for a long time or when it’s winter season.

There are two ways to restore your car’s battery charge. You can either jump start it and drive it for a few minutes if you need to use it right away. Otherwise, you may use a car battery charger to recharge if you don’t plan to use your vehicle yet.

Using a car charger takes longer. So, if you need to use your car, a jump start is the best option. So, how long does it take to charge a car battery anyway? Will you have enough time if you have an appointment in a few hours?

Let’s explore the timelines and see how long the process takes. We’ll also discuss some factors related to charging your car’s battery.

Factors That Affect the Car Battery’s Charging Time

1

Jump starter versus Car Battery Charger

A jump start provides up to 200 amps of power needed to jumpstart a dead battery. The car battery won’t fully charge, so you need to drive it for a few minutes so the alternator can fully charge the battery.

If you use a car battery charger, it may take an hour or more depending on the type of charging that you choose.

2

Amperage

You can adjust the amperage of your car battery charger depending on how dead the car battery is and the speed of charging.

If the battery is dead, opt for slow charging with lower amperage. This method is to keep your battery safe and long-lasting. Lower amperage means slower charging. The slower charging means longer charging time.

Slow Charging vs. Fast Charging

Fast charging is recommended if your car’s battery recently died when you accidentally left the lights on. Slow charging is recommended for a car battery that has been stuck up for a long time. Slow charging may require you to leave the car overnight.

Safety Measures When Charging Your Car Battery

Safety Measures

When your battery has already gone dead, you need to replace it.

Although your alternator charges the battery when you drive, it will cause stress on your engine and damage it. It is best to replace the battery once it has died. Also, if the car battery is dead, you’ll end up having to jump start or charge the car battery every time you need to use your car.

When using a car battery charger, the charger should be on a solid and stationary ground. Use the full length of the cables and keep it away from the car battery. You should also be in a well-ventilated area.

Never use fast charging if you intend to charge your car’s battery overnight. Opt for slow charging and lower the amperage. This practice is safer and makes your battery last longer. Check if the battery has been fully charged using a voltmeter. Most car battery chargers have built-in readouts.

Frequently Asked Questions

Frequently Asked Questions

How Long Does it Take to Charge a Car Battery?

Charging Time

When you use a low powered car battery charger, it may take 3 hours to overnight charge it depending on how dead the battery is. Fast charging may take up to an hour.

What is The Difference Between Voltage and Amps?

Amperes is the amount of electricity flowing in a current. In the case of a charger, it is how much electricity that goes through the battery to charge it. Voltage is the amount of potential energy. Potential means it is at rest. Voltage is the amount of energy in a device.

What is The Difference Between a Jump Starter and a Car Charger?

Both of them recharges the battery. The difference is that a jump starter gives out higher amps to jumpstart the battery and start it.

With a car charger, you need to let it charge an hour or so to fully recharge the battery and allow it to start.

Can I Use a Car Battery Charger to Jumpstart a Dead Battery?

No, a car battery charger is meant to charge the battery. You can charge it, but you cannot guarantee that it will start. Use a jump starter for that purpose.

Can I Charge All Types of Car Batteries?

No. Check the type of your car battery before charging it.

There are two types of batteries: Wet-cell batteries which contains sulfuric acid, and Valve-Regulated Lead Acid Batteries which are maintenance-free.

VRLA batteries also come in Gel Cell or Absorbed Glass Mat. Gel Cell batteries cannot be charged.

Conclusion

Your car’s battery is the heart of your vehicle. Without it, your engine and other electrical components of your car won’t function. It is important that you properly maintain the battery. You can do this by cleaning it, inspecting it, and checking electrical components that may cause it to drain.
