Car Battery 12 Volt How Many Amperes? Find Out Here!
How many amperes does a 12-volt car battery have? This is something that car owners need to know so that the car battery installed matches the specifications set by the car manufacturer. Instead of being curious about the ampere capacity of a 12-volt car battery, please pay attention to the following review for more details.
How Many Amperes Does a 12 Volt Car Battery Have?
A car battery with a voltage of 12 volts usually has different ampere ratings depending on the specifications provided by the car manufacturer. However, the average ampere rating for a 12-volt battery ranges from 35 amperes, 40 amperes, to 60 amperes.
How to Measure the Ampere Rating of a Battery
When you are about to replace a dead car battery with a new one, the ampere rating is the first thing you need to pay attention to. Ampere itself is the electric current produced by the battery to start the starter motor and the lights in the car. To measure or find out the ampere rating of a car battery, you can use several methods as follows.
1. Check the information on the battery casing
To find out the size or rating of the car battery, you can check the information on the battery casing. Usually, the ampere will be written with the symbol “Ah” and can be found next to the voltage symbol (“V/ Volt”). The ampere ratings for car batteries vary, ranging from 35 Ah, 40 Ah, 55 Ah, 60 Ah, or 65 Ah. Meanwhile, the voltage for car batteries is usually 12 Volts or 24 Volts.
2. Check the battery code information
Next, you can check the top of the battery where there is usually a code and the brand of the battery manufacturer. For battery codes circulating in Indonesia, they usually use two types of codes, namely JIS (Japanese Industrial Standard) and ETN (European Standard). To read these codes, you need to pay attention to the following methods.
How to Read the Old Version JIS Battery Code
For example, if you have a car battery with the code “NZ35LS”, the letter code “NZ” indicates that the car battery has a power reduction of approximately 20%. Meanwhile, the number code “35” after the letters “NZ” represents the ampere capacity of the battery, which is 35 Ah. The letter code “L” indicates that the negative terminal of the battery is on the “Left” side. And the letter code “S” indicates that the battery has a large terminal.
How to Read the New Version JIS Battery Code
For example, if you have a car battery with the code “35B19R”, the number code “35” represents the ampere rating of the battery, indicating that the battery has a capacity of 35 Ah. The letter code “B” is used to indicate the width and height of the battery. The number code “19” indicates the length of the battery, meaning that the battery is 19 cm long. Meanwhile, the letter code “R” indicates that the battery head is on the “Right” side.
How to Read the ETN Battery Code
For example, if you have a battery with the code “55520”. To read this ETN code, you need to pay attention to the following rules.
- If the first digit of the battery code is 5, it means 0.
- If the first digit of the battery code is 6, it means 1.
- If the first digit of the battery code is 7, it means 2.
- For the second or subsequent digits of the battery code, they are written with the same number.
Thus is the review regarding the ampere capacity of a 12-volt battery along with how to read it. If you intend to replace the battery, it is advisable to do the replacement at a Daihatsu authorized workshop so that the battery you install in the car matches the vehicle specifications or manufacturer recommendations.
