on account of reading this forum last night and after commuting and confirming it this morning, i brought my headlight inside from being attached to my bike.

it was a fully charged Taz 1200 that was outdoors overnight and not in use.

this morning after reading this, i knew there was potential for diminished performance but after trying to turn the light on, i immediately got the red blinking light indicating a very low remaining charge.

now that the light is inside, i turned it (without having charged it at all) back to a green, full charge light when on high.

i dont know much about charging the batteries while they're cold and whatnot but i guess i'll be bringing this light inside for my winter commute...
