About Battery Depth of Discharge Calculator

DoD formula

Depth of discharge (%) = (energy used ÷ total capacity) × 100. A 600 Wh draw from a 1,200 Wh pack is 50% DoD.

Battery life tip

Lithium often allows 80–90% DoD daily; lead-acid is typically limited to 50% for longevity. Size banks using the Solar Battery Bank calculator.

Frequently asked questions

Q: Is DoD the same as 100% minus state of charge? A: Yes—50% DoD means 50% charge remains.
