When it comes to heavy-duty power storage, 4D batteries are a popular choice for marine, RV, solar, and industrial applications. Understanding 4D battery dimensions and specs is crucial for proper installation and performance. This guide covers everything from 4D battery size and weight to 4D battery voltage and capacity, including key metrics like 4D battery cold cranking amps (CCA) and 4D battery amp hours (Ah).
Whether you’re upgrading your boat’s electrical system or designing an off-grid solar setup, knowing these specifications ensures you select the right battery for your needs.
1. 4D Battery Size and Weight
One of the first considerations when choosing a 4D battery is its physical dimensions and weight, as these affect installation and portability.
Standard 4D Battery Dimensions:
-
Length: 20.75 – 21 inches (527 – 533 mm)
-
Width: 8.75 – 9 inches (222 – 229 mm)
-
Height: 9.75 – 10 inches (248 – 254 mm)
-
Weight: 100 – 130 lbs (45 – 59 kg)
Due to their large 4D battery size and weight, these batteries are typically used in stationary or semi-stationary applications, such as RVs, boats, and backup power systems. Always verify clearance space before purchasing.
2. 4D Battery Voltage and Capacity
4D batteries are available in different voltage configurations, with the most common being 12V deep-cycle batteries for renewable energy and marine use.
Key Electrical Specifications:
-
Nominal Voltage: 12V (some models available in 6V for series connections)
-
Capacity (Amp Hours – Ah): 180Ah – 220Ah (for deep-cycle models)
-
Reserve Capacity (RC): 300 – 450 minutes (time a battery can run at 25A before dropping below 10.5V)
The 4D battery voltage and capacity make it ideal for long-duration power needs, such as running appliances in an RV or supporting solar storage systems.

3. 4D Battery Cold Cranking Amps (CCA)
For engine-starting applications, 4D battery cold cranking amps (CCA) is a critical metric. CCA measures a battery’s ability to start an engine in cold temperatures.
Typical CCA Ratings for 4D Batteries:
-
Starting/Deep-Cycle Hybrids: 800 – 1,000 CCA
-
Dedicated Deep-Cycle Models: Lower CCA (400 – 600) but higher Ah
If you need a 4D battery for both starting and deep-cycle use (e.g., marine dual-purpose applications), look for a hybrid model with high CCA and sufficient Ah.
4. 4D Battery Amp Hours (Ah) and Runtime
For off-grid and renewable energy systems, 4D battery amp hours (Ah) determine how long the battery can power devices before needing a recharge.
Calculating Runtime Example:
-
Battery: 200Ah 12V
-
Load: 50W fridge running 24/7 (~100Ah/day)
-
Usable Capacity (50% Depth of Discharge): 100Ah
-
Runtime: ~1 day before recharge needed
Deep-cycle 4D batteries with high Ah ratings (180-220Ah) are ideal for solar storage, trolling motors, and auxiliary power needs.
5. Comparing 4D Battery Types
Not all 4D batteries are the same—different chemistries and designs suit different applications.
4D Battery Types:
| Type | Best For | Pros | Cons |
|---|---|---|---|
| Flooded Lead-Acid | Budget backup power | Low cost, high CCA | Requires maintenance |
| AGM (Absorbent Glass Mat) | Marine/RV use | Maintenance-free, spill-proof | Higher cost |
| Lithium (LiFePO4) | Solar/off-grid | Lightweight, long lifespan | Expensive upfront |
For most users, AGM offers the best balance of durability and maintenance-free operation.
Conclusion: Choosing the Right 4D Battery
Understanding 4D battery dimensions and specs ensures you select the best model for your needs. Whether prioritizing 4D battery size and weight for installation, 4D battery voltage and capacity for solar storage, or 4D battery cold cranking amps (CCA) for engine starting, each specification plays a vital role.
For deep-cycle applications, focus on 4D battery amp hours (Ah), while dual-purpose users should balance CCA and Ah. With this knowledge, you can confidently power your boat, RV, or off-grid system with the right 4D battery.
