Whether you’re an avid angler or a recreational boater, knowing how long your trolling motor will run is crucial for a safe and successful day on the water. Our Trolling Motor Runtime Calculator helps you accurately estimate your battery life based on your specific setup and usage patterns.
Trolling Motor Runtime Calculator
Calculate how long your trolling motor battery will last based on your specific setup and usage patterns.
Battery Configuration
Higher Ah rating means longer runtime
Motor Usage
Typical usage is 20-50% of max draw
Estimated Runtime
Your trolling motor will run for approximately 8 hours under these conditions.
Usage Details
- Battery Capacity: 100Ah at 12V
- Usable Capacity: 80Ah (80% of total)
- Average Current Draw: 10.0 Amps
- Power Consumption: 120.0 Watts
- Usage Pattern: 50% duty cycle
Tips to Extend Runtime
- Reduce speed when possible - lower speeds dramatically increase runtime
- Use intermittent operation instead of continuous running
- Keep batteries well-maintained and fully charged
- Consider adding parallel batteries to increase capacity
- Monitor battery voltage to prevent over-discharge

Understanding Trolling Motor Runtime
Trolling motor runtime depends on several key factors:
- Battery capacity (Amp Hours)
- Motor current draw
- Battery voltage
- Usage patterns
- Environmental conditions
How to Use the Calculator?
Step 1: Battery Configuration
- Select battery setup from presets or enter custom values
- Battery capacity in Amp Hours (Ah)
- System voltage (12V, 24V, or 36V)
- Common Battery Configurations:
- Single 12V Battery (Group 24-31)
- Dual 12V Series (24V system)
- Dual 12V Parallel (increased capacity)
- Triple 12V Series (36V system)
Step 2: Motor Usage
- Enter average motor draw in Amps
- Select usage pattern:
- Continuous use
- Frequent use (75%)
- Moderate use (50%)
- Light use (25%)
