Car has been sitting over summer.
Went to start- Battery very dead. Jumped it easily. Started great.
Ran it around town for a half hour. Turned off and went to start- no luck.
Got a new battery fully charged.
Installed it. Went to start and it starts to turn over and then does the rapid ticking sound of a weak battery. Jumped it and starts easily.
Ran it for half an hour. Turned off and went to restart- it tries to turn over then ticky noise again.
Connections are good, but I am out of ideas. Help.
