I live in the polar vortex and so walking outside I’ve had a full phone battery go dead in under twenty minutes. We’re talking idk ≈ -40F. When it’s warmed up again there it is suddenly at 60%. I don’t expect to understand well because I know little about batteries, but what’s the deal? And how is it that once it’s warmed it is not only fully functional but has retained charge? At what temperature does this effect begin to take hold?
In: Technology
Along with sulfuric acid, water is inside of batteries and helps to transport electrons from the negative side of the battery to the positive terminal. When the water is frozen it still conducts electricity. Just horribly. Therefore your battery will act as tho it is drained. Get the battery back above freezing temperature should help restore the issues.
