The type and chemistry of batteries used in space are not the same as those used for terrestrial energy storage. The space batteries are not batteries of high capacity and many of them aren't chemical primary batteries at all. Some space "batteries" are actually RTGs, radioactive thermal generators which use plutonium nuclear decay to extract energy. Energy storage batteries on Earth would require heating to maintain their electrochemical properties and cannot be directly compared to space batteries.
Space batteries aren't meant to deliver huge amounts of power. They only output a few Watt-hours at best where terrestrial storage batteries for use in the power grid must be capable of delivering Killowatt-hours. Apples and kangaroos here. Also, space batteries need to be heated as well so they can function. They're not frozen and they will fail too if they get too cold. Space batteries also don't have to deal with water condensation since there is no humidity in space.
