Understand car batteries, what do these values mean: 12V 35Ah 520A(en) 480A(sae/gs)

When referring to car batteries, the values provide specific information about the battery’s voltage, capacity, and cold cranking amps (CCA) or starting power. Here’s a breakdown of what each value represents:

1. 12V: This indicates the voltage of the battery. Most car batteries operate at a nominal voltage of 12 volts, which is the standard voltage used in automotive electrical systems.
2. 35Ah: This stands for Ampere-hour (Ah) and represents the battery’s capacity. It indicates the amount of charge the battery can deliver over a specific period of time. In this case, the battery has a capacity of 35 Ampere-hours, which is a measure of how long the battery can provide a certain amount of current.
3. 520A (en): This value represents the battery’s cold cranking amps (CCA) or its ability to deliver power in cold weather conditions. CCA is a rating that measures the battery’s starting power when the temperature is freezing (0°F or -18°C). In this case, the battery has a CCA rating of 520 amps.
4. 480A (sae/gs): This value also represents the battery’s starting power, but it is measured using different standards. The “SAE” stands for the Society of Automotive Engineers, and “GS” refers to the German standard (Gesellschaft für Sonderfahrzeuge). Both standards are used to determine the battery’s cranking amps (CA) or starting power. In this case, the battery has a CA rating of 480 amps according to these standards.

These values provide important information about the battery’s performance characteristics, such as its voltage, capacity, and starting power. It’s crucial to choose a battery that meets your vehicle’s requirements and is compatible with its electrical system.

The Cold Cranking Amps (CCA) rating according to the SAE (Society of Automotive Engineers) standard. CCA is a measurement of a battery’s ability to deliver current in cold weather conditions, specifically at 0°F (-18°C). It represents the battery’s starting power when the engine is cold and needs a significant amount of electrical power to start.

The CCA rating is an industry-standard measurement and is commonly used to compare the starting power of different batteries. The SAE standard is widely recognized and used in North America and several other regions.
