Safety Precautions for Ebike Battery Charging and Maintenance

Storage Temperature
To prolong the battery's life expectancy, store it in a cool, dry place. Continuous exposure to heat affects the power unit’s performance. As a result, it has to be stored at a certain temperature, from 0°C to 20°C, which is preferable.

 

Proper Charging Measures
Charging your bike frequently helps maintain the power unit’s capacity. Regular charging also prevents cell degradation if you keep your bicycle stored for a long time. At the same time, never allow the battery to drain completely, nor should you leave it discharged for an extended period.

 

Cleaning and Protection
The battery must be kept clean and should not come in contact with dust, dirt, or even water. To clean it, you could use a damp cloth, but make sure the cloth is not dripping wet.

 

Routine Inspections
Once in a while, it is advisable to check the electric bike’s battery for damage, such as leakages, contact looseness, cracks, etc.

 

Precautions for Storing Ebike Battery

Partial Charge

Charge the battery partially, ideally around 40%-60%, as storing a battery that’s fully charged or fully discharged for a long time can reduce its lifespan.

Store Indoors

Store your e-bike’s battery in a cool, dry place away from direct sunlight. This will help maintain its capacity and lifespan.

Check Regularly

Even when stored, the battery will slowly lose charge. Check the battery’s charge every few weeks and top it up if needed.
