A battery tester is another crucial device that helps car owners accurately check the condition and performance of their batteries, preventing issues such as failed starts or dead batteries mid-trip, which can cause significant concern for drivers. If you want to ensure your car's battery remains in optimal working condition, SCMA is ready to provide consultation and professional testing services with modern and standardized equipment.
What is a battery tester?
A battery tester is an electronic device designed to thoroughly check the performance of a battery. Despite its relatively simple operation, it can accurately measure real electrical charge in cells and voltage levels. This tool also tests other important properties such as charging capacity and helps identify potential issues that could affect long-term performance and safety. With these features, a battery tester is an essential tool for anyone looking to maintain their batteries effectively.
What is the CCA (Cold Cranking Ampere) value?
The CCA (Cold Cranking Ampere) value measures a battery's ability to deliver current for starting an engine in cold weather conditions, indicating the amount of continuous electrical current that a battery can supply for 30 seconds at -18°C (0°F) without dropping below 7.2 volts for a 12-volt battery. For example, a battery with a CCA value of 600 can deliver 600 amps under these conditions. A higher CCA value indicates better starting performance in extremely cold weather. However, the CCA values may differ according to measurement standards such as SAE, EN, IEC, or DIN, each providing different values even for the same battery.
Why is this CCA (Cold Cranking Ampere) value important?
The CCA value is crucial as it indicates a battery's ability to deliver current for starting an engine, especially in low-temperature conditions. If the CCA drops below standard criteria, it may result in insufficient power for engine startup. Although engine start issues can arise from various factors, having an appropriate CCA value is a fundamental requirement. The CCA varies depending on the size, model, and type of battery, whether it's a maintenance-free (sealed) or semi-dry/semi-wet type. Therefore, selecting a battery with a suitable CCA for each vehicle's specific needs is essential.
The Primary Functions of a Battery Tester
A battery tester (Battery Tester) is an electronic device designed to comprehensively check the status and performance of a battery, starting from basic measurements such as residual charge in cells and output voltage, all the way to deeper analysis about the condition of the battery, such as its ability to store charge, which indicates remaining lifespan. Additionally, it can detect various defects that may not be visible to the naked eye but have direct impacts on long-term performance and safety.
Several Values Need to Be Measured in a Battery
A comprehensive evaluation of battery performance requires consideration of multiple factors, not just the measurement of no-load voltage (Voltage no-load) alone. Other important values must also be checked, especially when assessing starting capability. The most significant and clear indicator in this regard is CCA (Cold Cranking Ampere), which shows a battery's ability to deliver current at low temperatures. This value is crucial for determining whether the battery can provide sufficient current for an effective engine start.

Frequently Asked Questions
What is ACC?
ACC (Amp Cold Cranking) is another name for CCA (Cold Cranking Ampere), which refers to the battery's ability to deliver electrical current to start an engine in cold weather (-18 degrees Celsius) for a period of 30 seconds, with the voltage remaining at least 7.2 volts.
What is a CCA meter?
A CCA battery meter is part of a comprehensive battery testing device used to measure Cold Cranking Ampere values of the battery, to check if the battery still has sufficient starting power in cold weather conditions. There are dedicated CCA meters and those that are integrated into full-service battery testers.
How do you test a battery?
There are several ways to test a battery, including:
- Measuring voltage with a multimeter
- Load testing with a load tester
- Measuring CCA with a battery tester
- Testing electrolyte density with a hydrometer (for maintenance-free batteries)
- Visual inspection, such as checking for battery swelling, corrosion on terminals, or leakage of electrolyte
What are the testing standards for batteries?
Important testing standards for batteries include:
- SAE J537 standard by the Society of Automotive Engineers (US), which defines CCA test methods
- DIN (Deutsches Institut für Normung) standards from Germany
- IEC (International Electrotechnical Commission) standards
- JIS (Japanese Industrial Standard) from Japan
- EN (European Norm) standards from Europe
