DIN

📖 YOUCANIC Automotive Glossary

DIN (Deutsches Institut fuer Normung) is a German battery rating standard that measures a battery’s cold cranking performance using slightly different test conditions than the North American SAE CCA standard. The DIN test measures the current a battery can deliver at 0°F (-18°C) for 30 seconds while maintaining at least 9.0 volts (1.5V per cell), then continuing for an additional 150 seconds while maintaining at least 6.0 volts. Because the DIN test requires a higher minimum voltage threshold (9.0V vs. SAE’s 7.2V), DIN ratings produce lower numbers than SAE CCA ratings for the same physical battery.

DIN ratings are commonly used on European-market batteries and are often referenced in European vehicle service specifications. When replacing a battery on a European vehicle, you may encounter DIN ratings in the service manual rather than SAE CCA ratings. The approximate conversion is: SAE CCA ≈ DIN x 1.7. For example, a battery rated at 360 DIN is approximately equivalent to 612 SAE CCA. When performing battery registration (BRT) on European vehicles using the YOUCANIC UCAN-II, the scanner may request the battery capacity in DIN, EN, or SAE format depending on the vehicle manufacturer’s programming requirements.
