G35 Coupe won't start. Replaced the battery last year
 

A couple of months ago, I noticed my car would have a hard time starting. After a while, it would start fine. A few days ago, the lights and dashboard would turn on, but I'd get a clicking noise.

Today, there wouldn't even be any lights or anything (dome, headlights, brake lights, etc).

I changed the battery last year (DieHard) so I'm not sure what the problem would be.

Any help would be appreciated. Thanks.

Do you have a multimeter? Check the voltage of the battery first.

Could gave circuit problem as well draining from the battery when the car is off. I had that a couple of years ago went through two batteries in a month.

sounds like a battery . do a battery test and check for parasitic draws like coffey said
