if you buy any decent FRESH battery + keep it charged either with enough driving or a good charger it will LAASSSSSSTTTTT a long time! i traded a bike a while ago with 7 yo flooded OR battery + my 13 Vic Hammer has the OE battery in it!! batteries that are activated + set unsold are dieing a slow death!! retired but with 3 bikes, a car + truck use varies with the seasons + my C-Tek smart charger sees "action" on all of them on a regular basis!! charger was $75 + works for all, cheaper than most batteries these days. many motorcycle batteries are stored DRY + YOU activate them with the supplied "fluid" + charge as directed for a long life
