The specified standby current runs on the order of 55mA. My car sits for three weeks at a time and is fine.
But if the car is sitting for MONTHS at at time, of course it wont start.
Shut the car off, pull out the key, close doors and trunk, pop hood.
Take ground cable off battery, insert ammeter - wait for 90-120 seconds for all modules to hibernate.
If you see more than 60mA (.06 amp) or so, you have more current flowing than there should be.
If you see 55ma (.055amp) or less, it is fine.
If you see ZERO current, you have the meter incorrectly connected or the meter's internal fuse is blown.
BUT, in any case, leaving it for months without a battery tender or a charger on a timer is going to mean a dead battery.
