We al know that cars have self-charging capacities, thanks to the power of the alternator. However, there are times when the battery does not have sufficient charge. You will have to get an alternative charger.

In case of such a scenario, you wont want to stick around and wait for the battery to be fully charged.

So, how long doe does it take to charge a car battery at 2 amps?

Although the time may depend on the amp rating,  the average time taken to charge a car battery at 2 amps is 24 hours.

This is if you are using a 2 amp charger.

It will take between 12-24 hours if your are charging the car battery using a 4 amp charger.

A 10 amp charger will take you  between 3- 6 hours while a 20 amp charger will take you between  2-4 hours.

Do you want the fastest option? Then go for a 40-amp charger. It will only take you 30 minutes to fully charge the battery.

However, our focus is the 2 amps charge as it is deemed the safest way of charging your car battery.

This is despite the other charging options proving their viability.

Why is the 2 amps charger preferred?

We have just highlighted numerous other options for charging your car battery.

They include 10amps, 20amps and even 40 amps.

Why should I use a 2 amps charger and not the other options that we have highlighted?

There are numerous motivating factors behind the use of 2 amps charger.

The very first reason is safety. 2 amps chargers provide the safest way of charging car batteries. They provide the charges  to  a battery that has been completely drained in  the safest way possible without causing any electrical damage. Probably you know that bombarding an empty battery with large amounts of current at a time can be catastrophic.

Another reason behind the popularity of 2 amps charger is maintenance purpose. 2 amps is usually referred to as a maintenance charging in most applications where fast charging is not necessary.

The cost can also be a motivation factor behind the use of a 2 amps charger. In using high-capacity charger may also come with an extra cost and in some cases you may not be willing to spend that  much just to charge the battery.

Determine the charge time of the battery

How have we arrived at a conclusion that it will take 24 hours to charge a  car battery at 2 amps?

Well, there are numerous factors that we have considered and  a simple calculation that we have done.

These factors include:

• Car battery capacity: The capacity of a car battery is usually measured in Ampere-hours(Ah). Basically, this is the total amount of energy that the battery can store. Usually, the larger the capacity of the battery, the longer it will take to charge to n the fullest.
• Amperage of the charger: Here, we have to consider the capacity of the charger that we are using to charge the car battery. The amperage is usually measured in Amps and determines the rate at which it will discharge the amps. The higher the amperage, the shorter the charging time.
• Battery voltage: Well , most car batteries are rated at 12 volts. This is the potential difference of the car battery.
• State of the charge: This is a key factor that will determine the charging time. Are you getting the battery from 0% to full ? In our case, the car battery is at 2 amps.

After listing the above key determinants for the charging time, we will then do some calculations.

To find the charging time, we will have divide the battery capacity by the amperage of the charger.

Assuming that the car battery is rated at 12V and 50 Ah, we will go ahead to divide the 50ah/2A.

This ends up giving us 24 hours.

And that is how we have concluded that it will take an average of 24 hours to charge the battery.

If you use different chargers such as 10 amps and 20 hours, it is clear that you will get different numbers.

Dangers of using a large charger?

Other than the 2 amps, charger, we have listed other charging options such as 10amp, 20amp and  40amps.

It is always not advisable to charger using a charger rated more than 10amps. Here are some of the common risks:

-Risk of overcharging: A larger charger is designed to deliver large amounts of current within a short time. This will cause overcharging and eventually damage the battery. Overcharging can also lead to voltage spikes hence damaging the key components of the battery

-Reduce the battery life: Constantly using a large time will eventually reduce the lifespan of the battery.

-Generation of gas: Most chargers beyond 10 amps tend to generate gas in the battery during the charging process. This increases the risk of fire and even explosion.

-Inhibit the battery efficiency: Constantly using a fast charger will eventually affect the charging efficiency of a battery. By this I mean that it will be difficult to get your battery charge to the fullest whenever you use other batteries, or even when charging in car.
