🔋 Introduction
All batteries degrade over time—but not all degrade the same way.
LiFePO4 batteries are known for their stable and predictable degradation curve.
📈 What Is a Degradation Curve?
It shows how battery capacity decreases over:
- Cycles
- Time
📊 Typical LiFePO4 Degradation Pattern
Phase 1: Initial Stabilization
- Slight early drop
Phase 2: Stable Plateau
- Long period of slow degradation
Phase 3: End-of-Life Decline
- Faster capacity drop
📉 Example Data
- 0–1000 cycles → minimal loss
- 1000–4000 cycles → stable decline
- 4000+ cycles → faster drop
🔍 Why This Matters
Predictable degradation allows:
- Better system planning
- Accurate ROI calculation
- Reliable performance
⚖️ Comparison with Lead-Acid
- Lead-acid → rapid early degradation
- LiFePO4 → long stable phase
💡 How to Slow Degradation
- Reduce DOD
- Control temperature
- Optimize charging
📊 Real Insight
A well-managed LiFePO4 battery can still retain:
👉 80% capacity after 4000–6000 cycles
