How Long To Charge A Car Battery At 50 Amps? – Let’s Calculate

There are numerous ways to charge your car battery. Still, It may sound incredible to charge your car battery with a 50 amps charger.

Although you can charge your car battery with a 50 amps charger, you’ll require a proper setup, like an IPS system. However, the question is: how long does it take to charge a car battery at 50 amps?

There is no straight answer to this question as it completely depends on your charger. If you have a powerful charger that can serve 50 amps per hour, it will take only 1 hour and 10 minutes to charge a car battery fully.

You should be wary while charging your car battery with a 50 amps charger because a 50 amps charger has huge power that can overheat your car battery.

Today our entire focus will be on car batteries and how long to charge a car battery at 50 amps by using an inverter at home and the car alternator. Read the rest to know the details.

How Long To Charge A Car Battery At 50 Amps? Final Calculation

A car battery is such a vital organ of a vehicle. In fact, without this, a car can’t even start the engine. So, we often face a dead or unhealthy battery due to heavy use of it.

Calculation of Duration

Several elements of physics work in the charging term. However, the primitive is the amp that a charger can produce. The alternator is the charger that resides in a car and generates the electrical energy from the rotation inside it.

If your car is a luxury vehicle like BMW, Mercedes, Range Rover, or Jaguar, it is guaranteed that your vehicle alternator has the power to serve above 100 amps. The alternator can produce 40 to 60 amps if your car is a Toyota Corolla.

100 AMP Charger or Alternator

If you have a charger or alternator that can produce 100 AMP in an hour, it can recharge a car battery within a short while, like 30 to 35 mins.

If you are using a charger or inverter to recharge the battery, it generally takes meager time than an alternator. Furthermore, since it takes energy from the direct electricity line, you can enhance the range of the amp.

With a car alternator, the calculation is pretty straightforward.

50 AMP Charger Or Alternator

If you have a charger or alternator that can produce 50 AMP in an hour, it can fully recharge a car battery within an hour.

If you are using a charger or inverter to recharge the battery, it typically takes meager time than an alternator. As it’s powered by a direct electricity line, you have got the flexibility to increase the range of the amp.

10 AMP Charger Or Alternator

If you have a charger or alternator that can produce 10 AMP in an hour, it can recharge a car battery in 5 hours.

In case of charger or inverter, it takes short time than an alternator. And the deviation can be as much as 30 mins.

2 AMP Charger Or Alternator

If you have a charger or alternator that can produce 2 AMP in an hour, it can recharge a car battery by taking as long as 25 hours to charge fully. Certainly, it is not a wise option to recharge a car battery.

Steps Of A Car Battery Recharging Process In A Car

Before calculating the total duration of battery recharge, we must know how a car battery gets recharged. It is not that much of complex a process.

As we all know, one of the vital parts of a car is an alternator and which is responsible for charging the car battery.

If the vehicle is running, and we are not using many electronic devices in the car, it will only take 30 to 40 minutes to charge the battery fully.

Generally, if we maintain a car battery properly, the charge never goes below 70%, and this much is adequate to start an engine.

When we ignite an engine, it takes energy from the car battery to generate sparks in the sparkplugs to explode the fuel and air inside the cylinder. The mini-explosions in the cylinder cause the rotation of the crankshaft.

With that, the alternator starts its process since it is connected to the crankshaft. Lastly, the rotation of the alternator provides charge or energy to the battery.

As a result, the battery’s power never dries down until we use it heavily when the car is not running. Therefore, some uses are strictly prohibited like running the AC when the car engine is not running or taking charge of the battery to do another task.

FAQ’s

Here are some of the questions with the answers which may help you enormously while you phase such confusion.

Is It Ok To Charge A Car Battery At 40 Amps?

Yes, it is completely okay to charge your car battery with 40 amps. But, you must know the capacity of the battery so that you can detach the charger before it gains excessive heat.

For example, if you have a charger or alternator that can produce 40 AMP in an hour, it will recharge the battery within a short while like an hour and 20 mins.

How Long Does It Take To Charge A Car Battery With A 20 Amp Charger?

If you have a charger that can produce 20 AMP in an hour, it can recharge a car battery within a short while like 2 hours 30 mins. Yet, letting the battery charge for 2 hours 45 minutes is the wisest option.

How Long Can You Leave A 2 Amp Charger On A Car Battery?

If you have a charger that can produce 2 AMP in an hour, it can recharge a car battery by taking as long as 25 hours to charge fully. Certainly, it is not a wise option to recharge a car battery. Furthermore, you must understand how long to charge a car battery before connecting the inverter or charger.

Conclusion

A set of proper maintenance will increase the longevity of the battery. About a car battery, the alternator is the ideal charger to charge it. You can also use an inverter, which is not as good as an alternator.

However, after reading this write-up, you know how long to charge a car battery at 50 amps if you use an inverter or charger. It will help to calculate the time accurately and allow the battery to gain less temperature.
