Almost every other person today owns a vehicle of some sort, may that be a motorcycle, a car, a station wagon, or another. If you are going through this article, it means that you are a car owner and looking for detail about the charging period of your car.

There are a lot of factors that contribute to draining your car battery out of juice, such as staying idle for a long time, being used regularly on tough terrain, extreme weather conditions, and such. Now, being a responsible driver, you need to have the complete know-how of how a car battery works and how it can be charged, and how long it will take for that process so that you can manage your routine accordingly.

Now, before we get to charge a car battery at a standard 2 amps charger, you need to know a few basics which will help you better understand the entire process;

**What is a car battery?**

In vehicles today, a standard 12V battery is used. Each of these batteries is contained 6 cells which are each 2.1 volts when fully charged. Typically, a car battery is fully charged with 12.6 volts or higher. Even a small amount of voltage drop in the battery can make a huge difference in its performance.

**How does a car battery work?**

We can take an example of a wet cell battery that contains six cells and every cell is of a lead storage battery which includes the alternate plates. These plates are made of alloy grids and are filled with sponge lead or can be coated with lead dioxide. Now each of these cells is filled with a solution of sulfuric acid, which acts as an electrolyte. One can view the level of electrolyte through the filler cap that each of these cells has and they also let one add water to the battery.

Moreover, these cells are secured or joined from the positive plates with short but heavy straps, to the negative plates of the adjoining cell. There is a pair of heavy terminals which are plated with lead which serves the function of resisting corrosion. These pairs are present at the top, sometimes to the sides of the battery. At first, the car batteries utilized hard rubber cases with wooden plate separators but today’s units utilize plastic cases with woven sheets that served the function to keep the plates of cell from touching and short-circuiting.

**What is an amplifier? **

An Amplifier is a circuit that can gain power more than one. Now it can be a separate piece of equipment or a tool or it can be an electrical circuit carried or contained within another equipment or a device. Amplification is a rudimentary/foundational or a base to modern electronics and is broadly used in almost all electronic equipment.

**What are the amplifiers used for? **

As it is in the name, the amplifier’s purpose I to amplify the input signal so that the output signal can be produced which is very much in great level from the input one but has a similar wavelength as the output one. As a result, the major difference or change in the output signal will be the increased power level.

**Types of amplifier:**

There are many types of amplifiers which are as following:

- Audio Frequency Amplifier
- Intermediate Frequency Amplifier
- R.F. Amplifier.
- Ultrasonic Amplifier
- Operational Amplifier.

## How long to charge a car battery at 2 amps?

There a few different factors that can vary charging times. First, how much charge the battery contains at the moment, and the second, how many amps one is using to charge it at. The best tool one could have to maintain and recharge their battery is a battery tender.

**Amp-hour: **

Amp-hour means how much output power is given for a set of times to run a specified or a particular function of the car. A battery can put out one amp for fifty hours before it goes completely dead. There are specific things that draw a certain amount of amp hours. For example, headlights of most modern halogen bulbs can draw 8-12 amps but draws 20 amps in the older and muscle-type cars. So, if one has a 50 amp battery and headlights that draw ten amps then they could run for five complete hours. Now, there are more things than headlights that draw the amps. Because of that, there is an uncertainty of a battery being fully recharged on short trips and that is where charging might be needed if one would take a lot of short trips.

**Calculating how long the battery could charge:**

We have already mentioned the factors for charging the battery that is, how much power has been left and the rate of amp that we are charging it at. Now, for example, take a two amp charger. Determine how many amps are missing from the battery and find out about the time to charge through simple Mathematics by taking the amount that is missing and after that divide it by two. Suppose, we have a 50 amp battery that is half depleted, so it has 25 amps missing. One can divide 25 by two and will get 12.5. As a result, the battery will take 12.5 hours to get fully charged

**Why charge at 2 amps?**

By charging the battery faster, one can cause serious damage to it by buckling the battery plates and making the battery inoperable while damaging the areas of the car as well. So one must charge at a slower speed or two amps. Moreover, keep an eye on the battery when it gets hot and unplugs it. One can check for the temperature by the temperature gauge. Stop charging the battery when it gets to 125 degrees Fahrenheit. Also, by charging fast, one can hurt the useful life of the battery.

**Should one use a 10 amp charger or a 2 amp charger for a car battery?**

An automotive battery is 48 amps which also means that a 2 amp charger will take 24 hours but on the other hand, a 10 amp charger will take 5 hours. As we know, one should not do fast charging with the battery so, a 2 amp charger is safe for a car battery.

**Conclusion:**

Now that you know how a car battery works and how long it will take to charge it, you will be better able to take care of it and better able to adjust your routine with an unseen event.
