Backend Formula for the How Long Will a 100Ah Battery Last in a Boat Calculator
The core formula behind this calculator is simple yet effective:
Battery Life (hours) = Battery Capacity (Ah) x Battery Voltage (V) / Total Power Consumption (W)
Consider a scenario where your boat’s battery is rated at 12V and 100Ah, and your devices consume 200W. The formula calculates:
Battery Life = 100Ah x 12V / 200W = 6 hours
This formula helps boaters assess battery longevity, though variations exist, such as adjusting for inefficiencies or temperature impacts.
Step-by-Step Calculation Guide for the How Long Will a 100Ah Battery Last in a Boat Calculator
Let’s explore practical calculations:
Example 1: If a boater uses devices consuming 150W total, with a 12V 100Ah battery:
Battery Life = 100Ah x 12V / 150W = 8 hours
Example 2: For a higher consumption of 300W:
Battery Life = 100Ah x 12V / 300W = 4 hours
These examples illustrate how variations in consumption impact battery life, emphasizing the importance of accurate data entry.
