The Depth of Discharge (DoD) Impact Calculator helps you understand how deeply discharging your eBike battery affects long-term health, cycle life, and usable capacity.
A lower DoD means the battery is discharged less per ride, resulting in significantly increased lifespan and reduced degradation.
How Depth of Discharge (DoD) Affects Battery Life
Lithium-ion batteries last much longer when they are not drained to 0–20% frequently.
Manufacturers typically rate battery life assuming **100% DoD**, meaning a full cycle from full to empty.
But real-world usage often involves partial cycles.
Typical Battery Lifespan vs DoD
- 100% DoD: ~500–800 cycles
- 80% DoD: ~800–1200 cycles
- 60% DoD: ~1500+ cycles
- 40% DoD: ~2500+ cycles
- 20% DoD: ~4000–6000 cycles
Tip: For maximum lifespan, avoid draining below 30% and avoid charging above 90% whenever possible.
Frequently Asked Questions
Q: What is Depth of Discharge (DoD)?
A: DoD represents how much of the battery capacity you use before charging. 80% DoD means you use 80% of the battery each ride.
Q: What DoD level is best for battery life?
A: 40–60% DoD is optimal. Lower DoD dramatically increases cycle life.
Q: Does deep discharging damage the battery?
A: Yes. Regularly draining to 0–20% accelerates degradation and reduces long-term capacity.
Q: What happens if I discharge to only 50%?
A: You effectively double or triple the total cycle life compared to 100% DoD cycles.
Q: Is partial charging better?
A: Yes. Charging between 30% and 80% greatly increases battery lifespan.
