Backend Formula for the 12V vs 24V RV Battery Runtime Calculator
The formula behind the calculator is straightforward yet effective: Runtime (hours) = Battery Capacity (Ah) × Battery Voltage (V) ÷ Load (W).
For example, a 12V battery with a capacity of 100Ah powering a 120W load would result in a runtime of approximately 10 hours. The formula accounts for the relationship between voltage, capacity, and load, ensuring precise calculations.
Alternative formulas may consider factors like efficiency losses, typically around 85-95%, but the chosen formula provides a clear baseline for most applications.
Step-by-Step Calculation Guide for the 12V vs 24V RV Battery Runtime Calculator
Here’s a breakdown of the calculation process:
- Identify your battery’s voltage (12V or 24V).
- Determine the battery’s capacity in amp-hours (Ah).
- Calculate the total load in watts (W).
- Apply the formula: Runtime = Battery Capacity × Voltage ÷ Load.
Example 1: A 24V battery with 200Ah supporting a 200W load results in a runtime of 24 hours.
Example 2: A 12V battery with 150Ah supporting a 100W load results in a runtime of 18 hours.
Common errors include using incorrect units or neglecting to account for all devices in the load calculation.
