the battery charge ratio is low, the battery electrolyte may freeze. Maintain the
battery charge as close as possible to 100%, and insulate it against cold
temperature so that the machine can be started easily the next morning.
Measure the specific gravity and calculate the rate of charge from the
following conversion table.
