How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.
Formula
life = (m × C × u × 3600) / IInputs
| Name | Unit |

Diagnose
This tool does not attach diagnose observations.
Assumptions
- Capacity and utilization are inputs (example engineering values when using typical Mg/Zn tables). Not a hidden years-per-pound constant.
- Constant current for the whole life; no residual-mass or efficiency terms beyond utilization.
Provenance
- Charge-consumption life: t = (m × C × u) / I, with C in A·h/kg.
