| Specification | Value |
|---|---|
| Voltage | 12V |
| CCA | 590 -710 CCA |
| Dimensions | 10.06 x 6.89 x 7.75 inches |
| Reserve Capacity | 90 -105 minutes |
What Are the Key Specifications of Group 40R Batteries?
Group 40R batteries typically feature a cold cranking amps (CCA) rating ranging from 590 to over 710, which indicates their ability to start engines in cold temperatures. They also have a reserve capacity (RC) around 90 to105 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 means better performance during winter months, making **Group 40R batteries ideal for areas with harsh climates. For example, 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
| Battery Type | Average CCA Rating |
|---|---|
| Group 39 | 500 -600 |
| Group 40R | 590 -710 |
What Applications Are Best Suited for Group 40R Batteries?
Group 40R batteries are versatile and can be used in various applications, including:
- Automotive: Ideal for compact cars and sedans.
- Recreational Vehicles: Provides power for appliances and starting.
- Marine Applications: Suitable for smaller boats needing reliable starting power.
