They should never have treated you that way, with a known problem...dead battery. In addition, they should have run a complete diagnostics on the battery before selling if they had to jump it to move it off the lot. It is a shame how some ignorant dealers try to circumvent the system.
If they have a vehicle that sits for a long time, and they attempt to replace the battery at delivery, it is sometimes bounced since the failure is their fault for not charging. However, if it lasts in the vehicle for a few weeks, then they can slide it through warranty.
