Returned home from a weeks vacation. Had to run to store to fill frig from being away. 2014 Charger battery dead, has about a 6 month old AGM battery. 2012 company truck, battery dead, maybe a year old. No problem, any excuse to take the Roadrunner out - battery dead. 3 yr old NAPA Legend, always disconnected when not used. Screw it, I'll mow the lawn. Battery dead. Thank goodness for 10 yr old Jeep Wrangler, it started. Oh yeah, while vacationing, the Marine battery died in camper, and key fob battery died for truck. So, Just what is going on?
