Storing my scooter outside for winter

[FullyCharged]

Due to space limitation I am being asked to store my scooter outside for winter.  I can do all proper cover so that snow doesn't fall on it, but I am worried about the battery.  How much degradation can I expect?   should I charge it up once in a while?  I know teslas get stored outside even in winter, but they get trickled charged or whatever.   What about a scooter?  Is this a bad idea?

Not worth it if you can avoid it.  It would be something significant like 5% to 15% depending how cold.  These batteries degrade in general, but this just adds to it.   It is also bad for the motor.  Condensation could build up.
