I Feel Blessed
could be a bit lucky but my ST still has same battery from new, standard fit gel, which by its design will hold charge better when not used than a lead acid cell, anyway, have regularily only run mine in summer boost battery once maybe twice in winter and run trouble free all summer without charge, and will most likely do same this year, why are you lot having so much bother? Are you killing the battery by overcharging or are the chargers you use not suitable for gel packs as they overheat and distort if charged too quickly.
