Take it for what it's worth but my instructor at aviation mechanic school said "In theory, a fully charged battery will last indefinitely". So on that note, I use a solar charger on my outdoor 4x4/snowmobile truck and a Battery Tender on my tractor. Have had extremely good results from both. The solar is a cigarette lighter plug and the Tender is the quick connect that came with it.
