Have had this problem for a week now! Car will start fine 1 day then the next day is dead flat not even the lights on... have bought a new battery about a month ago so figured it can't be that.. when its jump started it starts mo problem! Ideas anyone please?

Have you checked for a short? Is there a drain on the battery when the car is off? DO you know how to check that? Have you had your alternator checked lately ?

First... where did you get the battery?
