Many car owners do not possess much knowledge about car batteries. You don’t need to get too mechanical to understand how a car battery works. But you should know the working and components of car batteries to manage your car efficiently. Car battery plays a vital role in igniting the engine, powering the multimedia system, and AC, and powering lights which is why it is of crucial importance for your car. In this article, we will cover car battery amperage and it's; related concepts that you need to know to charge and maintain your car battery.
Car Battery Amperage Test
A car battery amperage test is conducted to ascertain that the battery is offering adequate current to the attached load. The amperage is measured in terms of mAh (milliampere per hour). The performance of the battery is specified in terms of its voltage and amperage. The expected range of voltage and amp per hour is mentioned on each battery by the manufacturer. A specification of 12V 90Ah shows that the battery is expected to offer 12V power at 95 amps per hour.
The best way to test your battery amperage is to use a multimeter. Here is what you need to do to measure your battery amperage.
Start by disconnecting the battery from the circuit.
Then set up your multimeter. To do this you need to rotate the dial of the device and set it at the amp setting. Afterward, connect the black plug to the common terminal port (COM), and the red plug to the multimeter’s amp terminal.
Once the device is set, you should ask someone to start the engine. This will give you a realistic reading by showing you the actual reading of the current generated by the battery by starting the engine. After starting the engine, you need to connect the battery terminals to the multimeter leads by connecting the red probe to the positive and the black probe to the negative terminal respectively.
Note the reading that shows on the multimeter.
Compare the multimeter reading with the one that is mentioned on the battery by the manufacturer. If the reading is closer say 97.9 mAh for a 100 mAh battery then it means that there is nothing to worry about. But if the actual reading falls far below the reading mentioned by the manufacturer, say 60 mAh for a 100 mAh battery, then it is time to replace your car battery as early as possible.
Car Battery Amperage Rating
The car battery ampere rating tells us the capacity of the battery to store current. A larger-size battery will surely have a higher ampere rating. Generally, the amp rating of cars varies from 550 amperes to 1000 amperes. The amp rating of the car battery is mostly labeled as the amp hour rating. It is expressed as the amount of electrical charge stored in the car battery that offers 1 ampere of current supply for 1 hour.
This means that if a car battery has an amp rating of 100Ah then it means it can offer 100 amperes of energy for 1 hour. But this rating can vary with your need for more current or amperage implying that if you need 50-ampere current then the battery will last for 2 hours, if you require 25-ampere current then the battery can work for 4 hours, and so on.
Car Battery Amperage Output
A car battery amperage output is the maximum current supplied to the car battery at any given temperature. Amperage output is the volume of electricity generated inside the car battery that offers electric current supply to various equipment attached to the car. In simple words, Car battery amperage output refers to the output the current battery offers to run the car. It can vary for various batteries and the condition of the battery. The maximum amperage output can be explained by the chemistry and chemical reaction between the components of the battery and other physical dimensions. The output also depends upon the maximum capacity of the battery.
Normally manufacturers have mentioned a C-rating on batteries that states the maximum amperage output customers can expect. This output can be disrupted or lessened through thermal dissipation in the battery via internal resistance or by the internal chemistry that can affect the speed of the reduction and oxidation process inside the battery.
The output can also vary as per the attached load. This is because various loads need a varying level of amperage to start or function. A 1-liter hatchback needs very minimum amperage as compared to a diesel engine. So, the amperage output of the battery that can be sufficient for a 1-liter hatchback won't be sufficient for a heavy diesel engine. You need to ensure that the amperage output of the car battery matches your car's requirements or else you will have to face issues in the efficient functioning of the car and its components.
Certain factors can affect the car battery amperage output. One prominent factor is that you got too many components of a car that need immediate amperage when the car starts minimizing the current supply to the engine and making it difficult to even start the car. This is why it is advised to keep the components on hold (like the heating system or ventilation) until the car is started.
So, to enjoy the maximum output amperage of the battery you need to ensure that the chemistry of the battery and capacity is not disrupted.
The good news is that you can enhance the amperage output of your battery by connecting another battery in parallel. This will increases the capacity and amp-hour output of your battery. All you need to do is to make sure that the two batteries attached follow the same specifications. If you have a 12V 100Ah battery then you need to attach another 12V 100Ah battery with it rather than a smaller (6V 50Ah) or a bigger (24V 200Ah) battery with it. By connecting the batteries of the same dimensions and specifications in parallel you will double the amperage output. If you connect two batteries of 12V 100Ah in parallel then you will get total amperage output of 200Ah. These figures are just hypothetical to give you an understanding of how can you increase the amperage output.
