How can I safely discharge a large lead-acid battery, like a car battery or UPS battery? I assume I use a thick copper cord (I have that in the form of washing machine electrical supply lines, about a 1/4" thick) and then put a resistor in line. The problems I see with
Why Batteries Discharge More Quickly in Cold Weather
Lowering the ambient temperature causes chemical reactions to proceed more slowly, so a battery used at a low temperature produces less current than at a higher temperature. As cold batteries run down they quickly reach the point where they cannot deliver enough current to keep up with the demand.

Lead–Acid Batteries
The discharge state is more stable for lead–acid batteries because lead, on the negative electrode, and lead dioxide on the positive are unstable in sulfuric acid. Therefore, the chemical (not electrochemical) decomposition of lead and lead dioxide in sulfuric acid will proceed even without a load between the electrodes.
