Hello, I am here to help. If you have replaced the battery but it still is dying either you have a bad alternator but if you are sure it is good this leaves one thing which is a bad connection to the battery. You will need to clean both the negative and positive battery cables. If they are clean you also need to test for continuity on the battery cables. If there is a break in the wire that is under the protective coating it will be hard to see unless you test with a multi-meter. If the wires are good the alternator is at fault. It has a built in voltage regulator sometimes even will pass a test because they fail when they get hot so after a few minutes it will stop charging causing you with a dead battery.
