Is my car battery dead?

[kaboose]

Hello everyone,
I have 2014 Mazda 3. I left inside car lights on over night (about 9 hours) and now I cannot start the car but everything else works like I can turn on the radio and the headlights work. Does it mean my car battery is dead or there is some other problem? Do I need to jump the battery?
Thanks

@kaboose -Chances are it simply needs a boost to start. Once started, take it for a good long drive or preferably take it in to a shop and have the battery recharged properly, and also have it checked whether it holds the charge well.

I'd also suggest replacing your interior lights with LEDs. I left my LEDs on one night, actually almost a full day this past winter and it barely discharged the battery at all, car started immediately.

Thanks...I think will go to LED for interior lights
