Precautions for use of the battery
1. Precautions for use of the battery in a cold climate
Charge and discharge are the effects of a chemical reaction inside the battery. The
capacity of a battery declines in cold weather because the chemical reaction isn't as
active when the temperature is low. The mileage of E-bikes then often becomes shorter
in this case but note the cause of this phenomenon is not battery failure. We advise
when riding in colder conditions that you store the battery inside (more than 10°C)
when you are not riding. We also recommend that you charge the battery indoors where
the temperature is higher.
2. Precautions for long term battery storage
Remaining capacity decreases even if you don't use the battery, because the chemical
reaction continues and then a protection circuit becomes active. Our advice regarding
long-term storage is as follows.
1) When a battery is kept in the fully charged condition for a long time, the battery
suffers some damage. Try to keep the battery in a capacity condition that 3
LEDs of the remaining battery capacity indicator are turned on.
2) When the battery is completely discharged for a long time, the battery suffers
damage. Check the remaining capacity with the LED indicator every 3 months.
If, when checking the remaining-capacity status, only one or two of the LED’s
are lit, charge the battery until 3 LEDs are lit.
3) DO NOT leave a battery in high temperature environment. When temperature is
high, chemical reaction becomes more active, and the remaining capacity
decrease rapidly. Keep the battery in a dry place where it isn't exposed to direct
sunlight and the ambient temperature is less than 30°C).
4) Store the battery in a plastic bag to prevent a short circuit.

lights is ideal. Check capacity every 3 months and re-charge as necessary.
