so recently my car's battery went dead and i had to replace it. i got a new one, everything turns on now. however once my car is on, generally it'll take like 15 seconds and then the car rumbles and shuts off.

if this sounds familar, you know can you help me out? like wut do you think is the problem so i could take it to the mechanic asap.

thanks for the time.

Does it die out if you keep giving it gas? Battery terminals tight? Have you checked your alternator?

It sounds like your altanator is shot.
They can test it if your car can get to a autozone
