Winter Electric Bike Battery Maintenance Guide
 Dec 27, 2021|View:683

As the weather changes and the temperature starts to drop, it is important to ensure that you consider 

the impact this has on the electric bike battery. By following our simple recommendations, you can 

continue riding in the colder months without reducing the performance or range that you would normally

 achieve.


Let's start with why temperature has such a significant effect on the battery. Almost all electric bicycles 

use lithium batteries. We use a specific type of lithium ion battery, namely lithium cobalt manganese battery.


This particular type of battery has the lowest discharge rate of all electric bicycle batteries and has an 

impressive charging cycle. This means that it can be easily charged 1000 times without degrading 

performance, far exceeding many competitors on the market. Its charging time is also much longer 

than a lot of competition.


These electric bicycle batteries use a gel-like substance to transfer electrical energy from the batteries 

surrounding the battery. When the ambient temperature is below +5°C, this gel starts to harden. When

 this happens, the charge level (incoming charge and outgoing charge) that the battery can handle will

 decrease because the gel cannot move as freely as it does at normal operating temperatures.


With this in mind, it makes sense that the lower the temperature, the harder the gel, and the further

 reduction in charge.


Because even the slightest temperature change can affect the battery, riders often find that they have

 less mileage on a single charge in winter compared to spring or summer. However, by following the

 steps below, the impact can be minimized.


Store the battery in it

If you store your bicycle overnight in a cold place, such as an outdoor shed or garage, the battery will

 become cold. During this time, the gel inside will harden, thereby reducing the available range-this

 is especially inconvenient if you plan to ride long distances or commute.


We understand that it is not convenient to store an electric bicycle inside; therefore, we recommend

 removing the battery from the bicycle and taking it home when not in use.


The bicycle itself can be left in the shed or garage, because only the battery will be affected by the

 cold. Then, whenever you want to ride, you can reinstall the battery as usual.


Charge the battery

Similar to the above point, if the battery is charged in a cold environment, the charge will not move

 freely around the battery, so it will be difficult to reach full capacity. This not only affects the mileage,

 because the battery can never be fully charged, but also shortens the life of the battery.


Therefore, whenever you need to charge the battery, we recommend removing it from the bicycle 

and charging it indoors. It is also worth pointing out that the battery should be at room temperature

 before charging, so if you have just returned from a cold ride, please let the battery rest for a few

 hours before inserting it.


If not in use, remove the battery

If you don't like to ride in winter, and the bicycle will be idle for a while in winter, then we recommend

 that you take the battery out of the bicycle and store it indoors at room temperature.




To get the best battery maintenance effect, after taking it out, charge it to about 60% power, and then

 store it inside until you are ready to ride again. Our smart battery has useful features designed 

specifically for this situation. By pressing the button on the charger, it will charge (or discharge) the 

battery to 60%, and the battery management system will automatically put it in sleep mode to protect

 the battery when it is not used for a period of time.


Clean bike

Needless to say, in winter, you will definitely encounter more rain and dirt. This is not a problem,

 because the bicycle is designed to protect the battery in a downpour. However, you may need to clean

 the bike after the ride.


We do not recommend using a high pressure washer on our electric bikes, as this will damage the

 connection and force water into areas where it should not enter. Instead, wash the bicycle by hand

 (we recommend doing this with the battery installed to ensure that the terminals are covered), and then

 thoroughly dry the bicycle before removing the battery for charging or storage.


Practice good battery maintenance

Although it has nothing to do with temperature, it is best to completely drain the battery at least once

 every three months. This will help keep the maximum charging capacity as high as possible.


Don't worry about catching a cold while riding

Although we have said so far, don't be afraid to use your bike in cold weather!


Lithium-ion batteries heat up slightly during use, and this heat helps keep the battery temperature above

 5 degrees. It is important to emphasize that the cold will not damage the battery; our suggestions will help
