How to Use This Calculator
  1. Enter Depth of Discharge, Battery Chemistry, and LFP (LiFePO4).
  2. Set NMC, Lead-Acid, and Cycles per Day.
  3. Adjust Operating Temperature as needed.
  4. Review Expected Cycles and Years of Life (years).
  5. Use Total Equivalent Cycles and DOD Factor to inform your decision.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Depth of Discharge = 80, Battery Chemistry = 0, Cycles per Day = 1, Operating Temperature = 25 = 4 input(s) provided
  2. Calculate Expected Cycles
    Expected Cycles
    6000 = 6000
  3. Calculate Years of Life
    Years of Life
    16.4 = 16.4
  4. Calculate Total Equivalent Cycles
    Total Equivalent Cycles
    4800 = 4800
  5. Calculate DOD Factor
    DOD Factor
    1 = 1
