The battery is the heart of any electric bike. This guide covers battery types, maintenance, range optimization, and replacement costs.
Battery Types
Lithium-Ion: Most common, 1000+ cycles
Lead-Acid: Outdated, heavy, short lifespan
LiFePO4: Better durability, expensive
Battery Capacity (Wh)
250-400 Wh: Short trips (<30 km)
400-600 Wh: Commute (30-60 km)
600-800 Wh: Long range (60-100 km)
800+ Wh: Off-road (100+ km)
Range Factors
Terrain: Flat gives 20% more range
Weight: Each 10 kg reduces range 10%
Speed: Lower speed = more range
Age: Degrades 1% annually
Temperature: Cold reduces range 20%
Battery Lifespan
Typical: 3-5 years or 1000 cycles
Maintenance: 50% depth = double lifespan
Storage: Cool, dry place extends life
Charging: Full charge weekly preferred
Replacement Cost
250 Wh: ₹10,000-15,000
400 Wh: ₹15,000-25,000
600 Wh: ₹25,000-40,000
800+ Wh: ₹40,000-60,000
Battery Maintenance
- Charge regularly (weekly ideal)
- Avoid full discharge
- Store in cool place
- Keep connections clean
- Use original charger
- Check connections monthly
Fast Charging vs Slow Charging
Fast (DC): 30 mins – higher heat
Normal (AC): 4-5 hours – better lifespan
Trickle: 8+ hours – best for battery
Battery Recycling
Old batteries: Recyclable at dealers
Environmental: 90% recovery possible
Grants: Some states offer subsidies
Conclusion
Proper battery care extends life and maximizes range. Choose capacity based on your needs. Follow maintenance tips to get 5+ years of reliable performance.
