After 6 years, my battery appears to be on life-support (literally, as the voltage reads 14+V when running but drops to 12 or so immediately after cutting the engine)
First off, for those that have replaced batteries recently, where are you getting your direct-vent batteries and what warranty have you been seeing offered? In AZ, everyone stopped offering any type of warranty beyond 1 year free replacement (no pro-rata) except on top-tier batteries, but they still wouldn't warranty out past 2 years. Locally, VatoZone says they have pro-rata warranties in place, but the Interstate dealer says theirs are gone. Not sure if the Duralast has any direct-vent options, as past inquiries were in passing, not serious shopping.
Secondly, has anyone noticed that a worn out battery was affecting boost and power? Morning temps are in the 40s and 50s currently and even after 2 miles of warming up the engine, I am not even getting 10 lbs boost and the feeling is very sluggish. I got really personal with the charge pipe connector at the turbo and cannot feel any breaks in the hose, although I will be replacing it with silicone next week when I drain the coolant and replace all those hoses. Its been sluggish ever since I arrived in FL except for a small space of time over the summer when I got all my power back. I trailered the car to get it here, but some readers may recall all my whining posts about the lack of power over the last 2 years, as I can't seem to find any reason for it.
