07 S80 3.2 not starting
 

Car was parked for the winter , tried starting with a boost but no clicks from the starter but all lights are on as normal. Radio seems to be working intermittently aswell as saying low battery.

I'm thinking the battery might just be flat dead and not taking any charge or not producing the proper voltage so it's making everything a bit wonky. I'm going to replace the battery tomorrow but from what I read it could also be the fuseable link on the battery cable.

Does anybody have any experience with this ?
