Help! Slow Battery Discharge

If car sits for 2 weeks that is a long time for a battery to sit ... especially if this is a weekend cruiser .... with short weekend drives ... make sure that aftermarket add ons are supplied 15 power where recommended and not 30 power .... if the old school method of test light is no illuminated and ma draw is virutally nothing ... battery tender is the answer... i have same issue and battery tender is the key...
