Estimate ideal and adjusted battery runtime from capacity, voltage, load, efficiency, and usable depth.
Planning estimate only, not financial, tax, or legal advice. Verify assumptions and current rules before making decisions.

Nominal energy (Wh) = amp-hours × volts; runtime = nominal energy × usable fraction × efficiency ÷ load watts.
Sources support the method, terminology, or planning context. Editable assumptions remain your responsibility.
