The Battery Replacement Cost Estimator helps you understand the true long-term cost of owning an eBike battery.
Lithium batteries have a limited number of charge cycles, and this calculator shows your cost per cycle, cost per kilometer, and the total usable lifespan of your battery.
How the Battery Replacement Cost Calculation Works
This tool calculates several key values:
- Total energy per cycle: Capacity × Voltage (if Ah)
- Total lifetime energy: Energy per cycle × Total charge cycles
- Estimated total riding distance: Lifetime Wh ÷ Wh/km
- Cost per km: Battery price ÷ Total distance
- Cost per charge cycle: Battery price ÷ Total cycles
This gives you a realistic estimate of how much you are paying for every kilometer or every charging cycle your battery delivers.
Typical eBike Battery Lifespan
- Standard lithium-ion: 600–800 cycles
- Premium lithium-ion: 900–1200 cycles
- LiFePO₄ batteries: 1500–3000 cycles
What Affects Battery Replacement Cost?
- Battery capacity (Ah or Wh)
- Voltage rating
- Number of charge cycles
- Your riding efficiency (Wh/km)
- Market price of replacement batteries
Tip: Avoid deep discharging below 20% and don’t keep your battery fully charged for long periods — this helps extend cycle life.
Frequently Asked Questions
Q: How long does an eBike battery typically last?
A: Most lithium-ion eBike batteries last 600–1200 charge cycles before capacity drops to around 70%.
Q: How do I estimate cost per kilometer?
A: The calculator divides total usable lifetime distance by the battery price to determine cost per km.
Q: Does riding style affect battery life?
A: Yes. High speed, frequent full-throttle use, and low tire pressure increase Wh/km, reducing lifespan.
Q: Is Ah or Wh more accurate for cost calculation?
A: Wh is the true measure of battery energy, so Wh-based calculations are most accurate.
Q: Do premium cells last longer?
A: Yes. Panasonic, LG, Samsung, and LiFePO₄ cells generally offer higher cycle life.
