intermittent dead battery random after sitting long periods, 2 wks or 2days

What is your question?

replaced with new battery a few months ago, condition persists. random dead battery, no crank at all, no lights etc. battery tests good for cranking amps and meter does not detect a draw anyhwere. truck will go dead after a couple weeks or after a couple days. terminals and posts are clean and no service bulletins pertaining to any updates for this model. feeling deflated as it is yet another no fault found
