How Long Does It Take To Charge A Car Battery: An Informative Guide

You must be wondering why you should know how long does it take to charge a car battery. Well, there are many reasons behind this. Firstly, a vehicle’s battery does not have the same purpose as a smartphone. That is why you must be aware of the charging methods and time.

The top reason you should know the duration is to know when to start your car again. If you do not charge the battery adequately, it will die again soon and cause you to be stranded. Once again, you will have to jump-start to resume your journey.

Meanwhile, you shouldn’t charge your car’s battery after every time you go out. This is because the equipment can overcharge, and the electrolytes inside it will mix up. As a result, your battery will be damaged, and you will have to purchase a new one, which is expensive.

Apart from that, overcharging also causes car batteries to overheat and leads to further damage. That is why you must pay attention to the duration you charge the battery for.

How Long Does It Take To Charge A Car Battery While Driving?

This is one of the safest ways to charge your battery because it eliminates the risk of overcharging and damage. When you drive your vehicle, power from your engine will be transferred to the battery. This is done with the help of an alternator.

Once the battery is charged fully, the power will transfer to some other part of the engine. This means you don’t have to worry about overcharging your tool. You should note that this method of charging is also faster than external methods.

Typically, you can charge your battery enough within thirty minutes to allow your vehicle to start. Meanwhile, it can completely charge within an hour as well. 

The key thing to remember is that the time depends on the RPM value of your engine. The higher this value, the faster is the charging time of the battery.

How Long Does It Take To Charge A Car Battery With Linear Charger?

A linear charger is the simplest device you will find on the market to charge your dead car battery. First, you will have to put the charger into a socket and then connect it with the vehicle’s battery.

Setting up the charger takes some time and requires a certain amount of power. The primary thing you should note is that a linear charger works on low amperage. This means it can take many hours for your battery to recharge.

Here are the top amperages and the charging time for them:

  • 2 Amp – 1 to 2 days
  • 4 Amp – 12 hours to 1 day
  • 10 Amp – 3 to 6 hours
  • 20 Amp – 2 to 4 hours
  • 40 Amp – 30 minutes to 1 hour

Another key thing to keep in mind is that the linear charger does not shut down automatically. So there will be some risk of overcharging if you don’t track the progress.

How Long Does It Take To Charge A Car Battery With A Multi-Stage Charger?

A multi-stage charger is a device that recharges a dead car battery by providing power surges. This tool is better than the linear type because power surges prevent long-term damage.

The time this charger takes depends on the brand and model you are purchasing. A high-quality multi-stage device can recharge your car battery within an hour.

How Long Does It Take To Charge A Car Battery With A Trickle Charger?

This is the third type of charger you will find on the market for recharging a car battery. Typically, the device operates from 0.8 to four amps due to low output. You should also note that the trickle charger is not suitable for recharging a dead battery.

The time this charger takes for recharging depends on the amperage. Typically, it can take anywhere from twelve hours to three days. This is one of the reasons why the charger is mainly used for batteries that are not dead.

Can You Completely Recharge A Dead Battery?

The answer to this question depends on the condition of your battery and car. If the vehicle is in good shape and your only issue is the car battery, you can recharge it completely.

You can provide a jump start to the vehicle and recharge the battery using the car within an hour. Of course, this depends on the RPM of the engine and the distance you cover. However, if the battery is too old, you may not be able to recharge it completely.

Final Thoughts

This is everything you need to know on how long does it take to charge a car battery. The answer to this question is not as simple as it may seem. This is because the duration depends upon various factors such as charger type, amperage, and much more.

If you drive your car regularly, your battery will be adequately charged at all times. However, if you don’t use your vehicle for a week or more, you will be required to charge your battery using an external charger.

The best way to ensure that your battery recharges without damage is by charging it slowly. This will ensure that the equipment remains healthy and suitable for use.
