How to use the Battery Depth of Discharge Calculator
The Formula
Depth of discharge (%) = (energy used ÷ total capacity) × 100. A 600 Wh draw from a 1,200 Wh pack is 50% DoD.
Practical Example
Lithium often allows 80–90% DoD daily; lead-acid is typically limited to 50% for longevity. Size banks using the Solar Battery Bank calculator.
