LiFePO4 Cycle Life Explained
Dakota Lithium LiFePO4 batteries are engineered for extreme longevity. Here is what you can expect:
- 4,000 cycles at 100% depth of discharge (DoD)
- 5,000 cycles at 80% DoD
- 7,000+ cycles at 50% DoD
For most users, this translates to 10+ years of daily use. Compare that to lead-acid batteries, which typically last 300-500 cycles — that is 10x the lifespan.
What Does “Cycle Life” Mean?
One cycle equals a full discharge and recharge. If you use 50% of your battery capacity each day, that counts as half a cycle. At 50% DoD, your Dakota Lithium battery will last over 7,000 half-cycles — potentially 15+ years of real-world use.
The 11-Year Warranty
Every Dakota Lithium battery comes with an industry-leading 11-year warranty. This is not a prorated warranty — it is full replacement coverage. No other battery manufacturer offers this level of confidence in their product.
Cost Per Cycle: The Real Comparison
| Metric | LiFePO4 | Lead-Acid |
|---|---|---|
| Cycle Life | 3,000-5,000 | 300-500 |
| Cost Per Cycle | C$0.18 | C$0.60 |
| Warranty | 11 years | 1-2 years |
| Usable Capacity | 100% | 50% |
Even though LiFePO4 costs more upfront, the total cost of ownership is 3x lower than lead-acid over the battery lifetime.
