Solution
The battery performance decreases more in low temperatures than in normal temperatures, and sometimes the battery indicator will display a low remaining battery charge earlier than expected.
In cases like this, you may be able to restore the battery performance by warming the battery pack up in a pocket, etc. right before usage.
Please make sure that the battery contacts do not touch any metal object(s) (such as keys) in storage or transportation, as the battery pack may become short-circuited.
