CORE CONCEPTS
The Three Pillars of Battery Fitment
BCI group numbers, Cold Cranking Amps, and battery chemistry define accurate fitment. Together, they ensure the right physical size, starting power, and electrical compatibility.
BCI Group Numbers
BCI group numbers define the physical form factor of a battery: height, width, depth, and terminal location. These specifications ensure the battery will physically fit in the vehicle's battery tray and connect properly to the electrical system.
Cold Cranking Amps (CCA)
CCA defines the battery's ability to start a car in cold conditions. OEMs set minimum CCA requirements for each vehicle. Higher CCA than required is acceptable; lower is not. Catalogs must respect these minimums.
Battery Chemistry
The battery chemistry must match the vehicle's needs. Flooded (traditional), EFB (Enhanced Flooded), and AGM (Absorbent Glass Mat) each serve different applications — especially modern start-stop systems.
WHY IT MATTERS
BCI and CCA: The Foundation of Accurate Fitment
BCI group numbers and Cold Cranking Amps are two of the most important specs in battery fitment. Together, they define physical size and starting power — and both must align with what the vehicle requires.
​
Catalogs that ignore these factors can lead to costly fitment mistakes. Our data logic prevents that by ensuring every listing respects BCI dimensions, meets minimum CCA thresholds, and maps the correct battery chemistry to each application.
