Step-by-Step Engineering Calculation

  1. 1Rated Capacity: C=100 Ah at C20 rateC = 100\text{ Ah at C}20\text{ rate}
  2. 2Discharge Current: I=15.00 AI = 15.00\text{ A}
  3. 3Peukert Exponent: k=1.05k = 1.05
  4. 4Temperature Derating Factor at 20°C: 95%
  5. 5Peukert Calculated Runtime: T=H×(CI×H)k×DoD=5.10 hoursT = H \times (\frac{C}{I \times H})^k \times \text{DoD} = \mathbf{5.10\text{ hours}} (5h 6m)
