Mack,

Good practice is to remove your batteries during the winter months if you don't have them on a trickle charger. A dead battery will freeze and be permantly damaged. A properly cared for battery can last ten years. Below is info from an article

"It would actually be better to leave the trickle charger on the
battery. The freezing point of the electrolyte varies directly with the charge on the battery and therefore the concentration of
sulfuric acid in the electrolyte. At full charge, the freezing
point is very low, lower than -10 deg F, if my scratchy memory
serves. As the battery (self) discharges, the acid concentration is reduced until at full discharge the concentration is very weak and the freezing point rises to approach the 32 deg F FP of water. When the freezing point and the outdoor air temperature intersect, a frozen and almost always ruined battery results.
