What Is a Group 29 Battery?

A **Group 29 battery is a type of lead-acid battery designed specifically for automotive and marine use. It typically operates at 12 volts and is characterized by its robust construction, making it suitable for various vehicles, particularly those requiring reliable starting power. This battery is often used in cars, trucks, RVs, and boats.Chart: Key Features of BCI Group 29

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

What Applications Are Best Suited for Group 29 Batteries?

Group 29 batteries are versatile and can be used in various applications, including:

1. Automotive: Ideal for cars and light trucks.
2. Recreational Vehicles: Provides power for appliances and starting.
