re: Storing a vehicle - battery issues

with today's vehicles, there is always some small drain on the battery to keep things going (i.e. clock, alarm, and other electronics) that will eventually run a battery down. as some of the others mention, get yourself a decent quality trickle charger and even then, only plug it in for a day every week or so...I have even put the trickle charger on a timer to run one hour per day before.
