Pump Battery Calculator
Calculate how long your battery will power a water pump. Determine run time based on pump power, battery capacity, voltage, and efficiency factors for optimal system design.
Step 1: Pump Specifications
Understanding Pump Power
Pump power consumption varies with flow rate and pressure. Higher efficiency pumps use less battery power. Most submersible pumps range from 50W to 1500W.
Step 2: Battery Specifications
About Battery Life
Depth of Discharge (DoD) affects battery lifespan. Lead-acid batteries should not be discharged below 50%, while lithium can handle 80-90% discharge without damage.

Run Time Breakdown
Run Time Calculation Formula
Run Time (hours) = (Battery Ah × DoD × Battery Voltage) ÷ (Pump Watts ÷ Efficiency)
Battery capacity reduced by Depth of Discharge (DoD). Pump power adjusted for efficiency losses. Voltage matching between pump and battery is critical.
