I'm trouble shooting a slow starting condition on my TR8, and have discovered that my battery is showing around 13.25 volts, even after resting overnight. I don't think it is my meter, as my other batteries are showing the more expected 12.6-12.7 volts. Also, my battery tender is saying that the battery isn't achieving full charge (which is odd since it is showing such high voltage).
I'm not sure how old the battery is, I can't find any date markings. It was in the car when I got it almost two years ago. I haven't had anyone around to help measure voltage while starting, my theory is that the system voltage is dropping low when cranking the engine over, which is causing the fuel pressure to be slow to come up (fuel injected car).
I may swap the battery over from the 4A, just to see what happens.
