The term “4D” refers to a specific classification within the battery group system, particularly used for large lead-acid batteries commonly utilized in commercial applications. A group 4D battery typically measures approximately 20.75 x 8.75 x 9.88 inches and is designed for high-capacity applications such as RVs, boats, and off-grid solar systems.
Understanding the 4D Battery Classification
Definition of Group 4D Batteries
Group batteries are categorized based on their physical dimensions and performance characteristics. The “4” in “4D” signifies a specific size that fits within a standardized classification system established by the Battery Council International (BCI). This classification helps users select compatible batteries for various applications.
Specifications of 4D Batteries
Dimensions and Weight
A typical group 4D battery has dimensions of approximately:
- Length: 20.75 inches (527 mm)
- Width: 8.75 inches (222 mm)
- Height: 9.88 inches (250 mm)
These batteries are relatively heavy, often weighing between 60 to 70 pounds (27 to 32 kg), depending on the manufacturer and specific model.
| Specification | Measurement |
|---|---|
| Length | 20.75 inches (527 mm) |
| Width | 8.75 inches (222 mm) |
| Height | 9.88 inches (250 mm) |
| Weight | Approximately 60-70 lbs |
Voltage and Capacity Ratings
Group 4D batteries typically operate at a nominal voltage of 12 volts and can have varying capacities ranging from 100 to over 200 amp-hours (Ah), making them suitable for applications requiring sustained power over extended periods.
Applications of 4D Batteries
Common Uses in Various Industries
Group 4D batteries are commonly used in several applications:
- Recreational Vehicles (RVs): Providing power for lights, appliances, and other electrical systems.
- Marine Applications: Serving as starting or deep-cycle batteries for boats.
- Off-grid Solar Systems: Storing energy generated from solar panels for later use.
- Backup Power Systems: Used in medical equipment or security systems where reliable power is crucial.
Comparison with Other Battery Groups
Differences Between 4D, 6D, and 8D Batteries
While group batteries share similar characteristics, they differ primarily in size and capacity:
| Battery Group | Dimensions (L x W x H) | Typical Capacity (Ah) |
|---|---|---|
| 4D | 20.75 x 8.75 x 9.88 inches | ~100 to ~200 |
| 6D | Larger than group 4D | ~200 to ~300 |
| 8D | Largest among these groups | ~250 to ~400 |
The choice between these groups depends on the specific power requirements and space constraints of the application.
Advantages of Using 4D Batteries
Benefits Over Other Types
Group 4D batteries offer several advantages:
