Station Battery
From Unofficial Stationeers Wiki
As for v0.2.3967, every battery is subject to normal drain or conditional "cold" drain.
"Cold" drain occurs if pressure bellow armstrong limit(6.3KPa)(full drain) or below 0C(drain depends on temperature).
Normal drain amount - 10, "cold" drain amount - 50. If atmosphere is "indoor" then drained energy transfered to atmosphere.
Sealed vacuum take full "cold" drain amount, but open vacuum disable all drains(praise the Moon).
Battery cells act little different they skip pressure part, so only temperature matter. And no energy transfer occurs.
Edits made by Jimmyberg actually made energy requirement less clear. Because of word wrapping, I incorrectly read it as 600kJ, instead of 3.6MJ. I propose to use SI units instead of large number with spaces.
