Have a 2004 ....battery went dead got a new battery...went out 24 hrs later totally dead... charged battery...car started ...went out after 20 min car started. Went out after 45 min car started... Went out after 3 hrs cars dead... all lights, radio , A.C. off. Any ideas what's draining the battery...... up till this point car has been running great..

 

Welcome to the forum.

Need to charge the battery while it's disconnected and then reconnect the battery w/ an ammeter in series with the positive cable. Assuming that there is some current draw, then start pulling fuses until if goes away.
