Why Battery Storage Matters
If you leave an electric bike unused for a long time and store its battery improperly, you risk capacity loss, chemical degradation, or even swelling and short circuits. By storing it correctly, you extend its service life and prevent safety hazards.
Pre-Storage Checks and Preparation
Before storing your battery, take the following steps:
- Check for any damage or swelling on the battery casing.
- Ensure the battery holds 50%–70% charge.
- Clean the battery terminals to prevent dust and corrosion.
- If the battery is removable, store it separately in a fireproof bag.
Ideal Environmental Conditions for Storage
Store your battery under the following conditions:
- Temperature: 10°C–25°C (avoid extreme heat or cold)
- Humidity: Low humidity, good ventilation
- Keep it away from direct sunlight or heat sources (e.g., radiators, stoves)
- Use a fireproof safety box or metal cabinet for added protection
Maintenance Tips During Long-Term Storage
If you plan not to use the battery for more than 3 months:
- Check the battery charge once every month
- Recharge to 60% if it drops below 30%
- Avoid keeping the battery at full or empty charge for extended periods
- For storage beyond 6 months, use a maintenance charger with trickle charging
Prohibited Actions and Safety Warnings
Never do the following when storing your battery:
- Leave it in humid or corrosive environments
- Let it touch metal objects (risk of short circuit)
- Store it at 0% or 100% charge for long durations
- Wrap it in plastic bags, which block proper heat dissipation
Good Storage = Long Battery Life
Electric bike batteries are costly. A proper storage strategy significantly improves their lifespan and performance stability. Whether you’re storing for the winter, during long-distance transport, or keeping backup inventory, mastering these storage techniques is essential.
Conclusion
Battery manufacturers should provide customers with storage manuals and adopt smart BMS (Battery Management Systems) that automatically monitor charge and temperature during storage. This ensures even greater safety.
