Car dead (not fuel relay)

My battery is dead, when I push start it, it will start and after I drove it around and shut it off it started again, but this morning it was dead. I think the battery might be dead for ever, since I bought the car used I’m not sure how old it is. But what do you guys think?

Only sure way is to test it with a Voltmeter…or unless you have a battery testing machine to load test the sucker.

Alright i got a new battery… its working fine now… I’m dam sure its the battery because it was making bubble nosies when the car was off.
