Battery Capacity Calculator
Calculate the required battery capacity for your application with our comprehensive calculator. Determine optimal battery performance based on power requirements, usage patterns, and system efficiency.
Step 1: Power Requirements
Understanding Power Consumption
Power consumption is the rate at which your device uses energy, measured in watts (W). To calculate daily energy needs, multiply power consumption by operating hours.
Step 2: Battery Parameters
About Depth of Discharge
Depth of Discharge (DoD) indicates how much of a battery’s capacity can be used. Lower DoD extends battery life but requires larger capacity. For example, lead-acid batteries typically use 50% DoD, while lithium-ion can use 80% or more.

Battery Capacity Formula
Capacity (Ah) = (Power (W) × Hours × Days) / (Voltage × DoD)
To calculate battery capacity: Multiply power consumption by daily operating hours and days of autonomy, then divide by the product of system voltage and depth of discharge (as a decimal).
