Electric Bike Battery Care Tips for Longer Life (2025 Guide)

🔋 Introduction

An electric bicycle’s performance and range depend mainly on its battery health. Whether you use a 250W 36V Li-ion battery, like most CANDULLA bikes, or a higher-capacity model, proper care ensures long life, stable performance, and maximum riding range.

In this guide, you’ll learn practical and simple battery care tips to keep your e-bike running smoothly for years.

1. Avoid Full 0%–100% Charging Cycles

Lithium-ion batteries live longest when they stay between 20% and 80%.

✅ Best practice:

  • Charge when it reaches 25–30%

  • Unplug at 80–90%

  • Avoid draining to 0%, which strains the battery

❌ Avoid:

  • Keeping the battery at 100% for many hours

  • Deep discharge cycles regularly

2. Use Only the Original Charger

Every e-bike battery has a specific voltage and current requirement.
Using the wrong charger creates overheating and cell damage.

🔧 Follow this:

✔ Always use the manufacturer-provided charger
✔ Check that the plug is not loose
✔ Charge on a flat, non-metal surface

3. Keep the Battery Cool While Charging

Heat is the number one enemy of lithium batteries.

🔥 Avoid:

  • Charging under direct sunlight

  • Leaving battery in a hot car

  • Storing near stoves, heaters, or windows

🌡 Best temperature:

15°C–30°C is ideal for charging and storage.

4. Don’t Wash the Battery With Water

Electric bike batteries are water-resistant but not waterproof.

🚿 Avoid:

  • High-pressure water spray

  • Soaking the battery in wet cloth

  • Washing connectors with water

✔ Instead:

  • Clean with a dry or slightly damp cloth

  • Protect battery during bike washing

  • Check connectors for dust after rainy rides

5. Charge the Battery at Least Once Every 20–30 Days

If you don’t use your e-bike often, don’t leave the battery idle.

🗓 Storage rule:

  • Maintain 50–60% charge

  • Charge once every 3–4 weeks

This prevents battery cells from going into deep sleep mode.

6. Never Charge the Battery Immediately After a Ride

After riding, the battery becomes warm.

⚠ Why it matters:

Charging a hot battery reduces its lifespan and can damage internal cells.

✔ Best practice:

Wait 20–30 minutes before charging.

7. Avoid Overloading the Bike

Extra weight = more motor load = faster battery drain.

✔ Tips:

  • Maintain proper tire pressure

  • Avoid unnecessary luggage

  • Ride at an optimal speed (20–25 km/h for best range)

8. Keep Your Software & Display Updated

Some e-bikes—like CANDULLA models with smart displays—may receive updates that improve battery management.

✔ Check for:

  • Firmware updates

  • Battery calibration

  • Range optimization settings

9. Store Battery in a Safe, Dry Place

For long-term storage:

✔ Ideal:

  • Room temperature

  • Away from moisture

  • Away from metal objects

  • Avoid direct sunlight

❌ Never store:

  • In extremely hot/cold environments

  • Near flammable objects

10. Replace the Battery Only With Certified Models

Cheap, non-certified batteries can damage controllers and motors.

Always choose:

  • Original CANDULLA batteries or

  • IS-certified lithium batteries

🔚 Conclusion

Taking simple steps like charging properly, protecting the battery from heat, and avoiding overuse can double the lifespan of your electric bike battery. Whether you ride a CANDULLA Black Hawk, a daily commuter, or a mountain e-bike, these habits will keep your rides smooth and safe for years.
