Specification Value
Voltage 12V
CCA 675 -850 CCA
Dimensions 13 x 6.75 x 9.25 inches
Reserve Capacity 140 -210 minutes

What Are the Key Specifications of Group 29 Batteries?

Group 29 batteries typically feature a cold cranking amps (CCA) rating ranging from 675 to over 850, indicating their ability to start engines in cold temperatures. They also have a reserve capacity (RC) around 140 to210 minutes, allowing them to power electrical systems when the engine is off.

How Do Cold Cranking Amps (CCA) Affect Performance?

Cold Cranking Amps (CCA) measure a battery’s ability to start an engine in cold conditions. A higher CCA rating translates to better performance during winter months, making **Group 29 batteries ideal for areas with harsh climates. If you live in a region where temperatures frequently drop below freezing, opting for a higher CCA battery can ensure reliable starts.Chart: CCA Ratings Comparison
