Have a Mazda 3 that the battery is dead after 2 days of sitting , battery has been tested is 1 yr . old and is ok , alternator is ok , seems to be a constant draw on battery when not driven , No interior lights are left on , trunk light is not on ..any ideas ?

 

What brand of battery?

 

Sounds like you have a parasitic drain somewhere. Time to break out the multimeter and start tracing it (or have a shop do it).
