[PA135i]

I am coming up on the 4 year mark for my 135i and in the past replaced batteries at 4 yrs. as preventive maintenance. I asked my SA and he said I would get symtoms before it goes dead. ie. the heated seats stop working... etc.

I know this battery is around $350 installed, but would rather be safe than sorry. Was wondering what you guys plan to do as you approach the 4 yr. mark.

thanks
