Batteries have a code that indicates the size and type of battery. This code differs depending on the specification of the battery construction. There are 3 different specifications in the world that regulate the size, power and performance of batteries and they are the European (EN), the Japanese (JIS) and the American (BCI).
The date code on a car battery is usually stamped on the battery case and consists of a combination of letters and numbers. The first letter represents the month the battery was manufactured (A for January, B for February, etc.), while the second digit represents the year (9 for 2019, 0 for 2020, etc.).
The first number (75 in this case) represents the battery’s ampere-hour (AH) rating, which is a measure of the battery’s capacity. The letter D represents the battery’s group size, while the number 23 indicates the battery’s overall dimensions. The letter L represents the battery’s polarity and venting requirements.
It is measured in minutes and indicates how long the battery can run without being recharged. Amp-hour rating (Ah) is a measure of a battery’s capacity over a 20-hour period. The higher the Ah rating, the longer the battery can provide power. Understanding these battery specifications is crucial when choosing a replacement battery for your car.
European standard batteries use 2 types of codes. One comes from the older coding according to the German DIN standard and the other is the newer coding according to the European Union (EN) standard. It is always five digits and consists of two parts:
Battery codes are sometimes standardized by organizations such as the International Electrotechnical Commission (IEC) and the American National Standards Institute (ANSI). These bodies have established guidelines for labeling batteries, ensuring that codes are consistent and universally recognized.
