I prefer cheapskate maintenance. Acid eats things for a living and the difference between cold acid and very warm acid is staggering. Nothing on the face of the earth beats temperature corrected constant voltage maintenance for lead acid batteries. It is foolish for someone in Vancouver BC or Miami Florida to insist "his way" of battery storage is "The Right Way". Unless it incorporates temperature corrected constant voltage. The object is to find a happiest medium between sulfation and plate erosion.
Down here high temps with no temp compensation plus washboard terreceria off pavement driving makes for removing a battery from an oven then strapping it to a hardware store paint shaker.
