1. The Biggest Mistake Buyers Make
👉 Choosing battery based on price only
2. What Is Cycle Life?
Cycle life = number of charge/discharge cycles
- Lithium: 4000–6000 cycles
- Lead-acid: 300–800 cycles
3. Real Cost Comparison
| Battery | Price | Cycle Life | Cost per Cycle |
|---|---|---|---|
| Lead-acid | $100 | 500 | $0.20 |
| Lithium | $300 | 5000 | $0.06 |
👉 Lithium is 3x cheaper long-term
4. ROI Insight
Lithium batteries:
- Last 8–10 years
- No replacement cost
- Lower maintenance
5. Buyer Strategy
