How to properly maintain your e-bike battery

The more conscientiously you treat your e-bike, the more durable its components and drive parts are. Just before the winter break should therefore think about the proper storage and handling.

Here we tell you helpful tips for your battery to extend its life.

E-bike batteries are an expensive affair, so you should take good care of the battery so that it reaches the maximum life. This is achieved depending on the manufacturer between 500 to 1000 charging cycles, then the battery must be replaced. Nevertheless, there are a few tricks to ensure that the battery remains powerful for as long as possible. We have summarized the tips from the pros Bosch, BionX, Shimano, Yamaha, BMZ, FAZUA and so on.

Care Tips

E-bikes are equipped with the latest Li-Ion batteries without "memory effect". This means that the battery will not lose capacity due to partial charges. The battery could therefore theoretically be charged after each trip.

  • Load

Extreme temperatures are bad for the battery, especially when the battery is charging. Charging the battery in direct sunlight, near heaters, or at very high or low temperatures is detrimental to the battery. This can significantly reduce the life of the battery. Therefore, BionX recommends charging the battery at room temperature (about 20 ° C / 65 ° F) and giving it enough time to reach room temperature. The battery can be charged both on the bike and separately. In addition, the loading should always be done in a dry environment.

  • To store

Unused batteries are best stored in a cool place between 10 ° C (50 ° F) and 25 ° C (77 ° F). The battery should never be stored in locations above 45 ° C (113 ° F) or below -10 ° C (14 ° F) and should never be exposed to extreme temperature changes. Basically, it is important that the battery is protected from moisture during storage to prevent corrosion at the plug contacts. Never drop the battery and avoid mechanical damage. Damage could lead to short circuits or overheating of the battery.

  • Wintering

Store your battery in a dry place and at temperatures between 5 ° and a maximum of 20 ° C. When the battery is completely empty, this means the most stress for the battery. Therefore, the ideal state of charge for longer storage times, e.g. about the winter break at about 30% to 60% or two to three light emitting diodes on the battery charge indicator.

  • Cleaning and care

A direct jet of water should not be used to protect the electronic components in particular. Therefore, before every cleaning of the e-bike, remove the battery, clean it with a damp cloth and occasionally clean the connector poles and lightly grease.

  • Winter operation

If the e-bike is also driven in winter (especially below 0 ° C), the manufacturers recommend that the battery charged and stored at room temperature be put into the e-bike just before the start of the journey. For a longer trip in the cold you should use a thermal protection cover.

  • Transport

For transport, the battery should always be removed from the e-bike and transported safely in the car, to protect the charging contacts on the e-bike there are caps, so that the contacts are not wet when transported on the vehicle.

  • Disposal

Please note: Defective batteries must not be disposed of with household waste! Take unused batteries for proper disposal.
