Official Response
depends how cold - per the manual


For best results, your battery should be charged in a location where the
temperature is greater than 32°F (0° C) and less that 104°F (40° C).
Do not store it outside or in vehicles.

For Lithium-Ion battery pack storage longer than 30 days:
Store the Lithium-Ion battery pack where the temperature is below 80°F (26°C) and
free of moisture.
Store Lithium-Ion battery packs in a 30%-50% charged condition.
Every six months of storage, fully charge the Lithium-Ion battery pack.
Exterior may be cleaned with a cloth or soft non-metallic brush.
NOTICE:
This battery pack has equipped with an advanced self-maintenance
function. It can maintain 30% of its charge capacity automatically after it is stored
over one month.

I live in Minnesota and just finished snow throwing a three lane by about fifty foot driveway of five plus inches of snow.  I charge my batteries (two 7.5Ah) afterwards and leave them in the basement until the next round.  If over 30 days between snow fall (it happens), I will charge them again before going out.  I would never recommend leaving them in my unheated, uninsulated  garage.  Fifteen below or more can never be good for any battery.  I bring in my motorcycle batteries and those spendy DeWalt 20v batteries too.
