I. Charging Techniques: Avoiding "Freezing" and "Overcharging"
1. Warm up before charging: Do not charge the battery directly in low temperatures. It's best to park indoors or in a garage and let it warm up naturally (rest for at least 30 minutes) before charging. If the battery is frosted, wipe it dry first, otherwise it may short-circuit.
2. Choose the right charging environment: Charging indoors at temperatures above 5℃ is most efficient. Charging is slow in winter; don't try to save time by "charging overnight" (over 8 hours), as this can easily cause bulging and leakage.
3. Control charging time: After the charger's green light comes on, don't rush to unplug it. Let it float charge for another 1-2 hours to fully charge the battery. However, unplug it within 1-2 hours after it's fully charged to avoid overcharging.
4. Always use the original charger: Different brands have different voltages and currents; mixing them may cause overcharging or undercharging, damaging the battery.
II. Storage Tips: Don't Let Your Battery "Starve or Freeze"
1. Fully Charge Before Long-Term Storage: If your bike will be stored for more than a month, charge it to 50%-70% before storing to avoid depletion.
2. Regular Top-Ups: If not used for a long period, charge the battery every 1-2 months to prevent sulfation.
3. Storage Location: Store in a dry, well-ventilated place with stable temperature (such as an indoor garage). Do not leave it outdoors, especially in rainy or snowy weather.
III. Riding Habits: Saving Power Protects the Battery
1. Smooth Riding: Avoid sudden acceleration and braking, as these operations draw large currents and damage the battery.
2. Reduce Power Consumption: In winter, use the heater and headlights less; coast as much as possible to reduce the burden on the battery.
3. Check Tire Pressure: Insufficient tire pressure increases rolling resistance and consumes more power. In winter, tire pressure can be slightly higher than the standard value (e.g., 2.4-2.6 bar), but do not exceed 2.8 bar.
IV. Regular Maintenance and Inspection
1. Cleaning and Maintenance: Check the battery terminals monthly. If oxidation is present, sand it down and apply a small amount of protective grease to prevent rust.
2. Performance Testing: If you notice a significant decrease in range (e.g., 50 kilometers in summer but only 30 kilometers in winter), it may indicate battery aging. It is recommended to have the battery capacity checked at a professional shop.
