Battery Question
2004 vette and my battery's green eye is not green! I use a float charger from time to time and it seems to charge it just fine. I have read where the green eye is a built in electrolite tester. I tested the battery under load of hood light and it reads 12.50 with the light on and when the light goes out it creaps up to about 12.75 volts.
My question is: Just how important is this green eye anyway? Do I need a new battery if it wont turn green and how long is the battery warranty on a new car.
Thanks

If its a new car , take it back to the place you got it and have them check the battery with a battery tester. But to say they will give you a new one I don't know if thats covered in the deal you had with the people. But the green eye just gives you a clue the battery is good, if the green eye is going out something is not right with the battery, and in that go have it checked.
But it doesn't mean your battery is bad it could also mean your having a charging problem or something like that. So have them do the test with battery in the car so they can check your alternator and charging system.

Part of testing a battery is to test it under a load. The battery's ability to be able to recharge (and how quickly) after that is a good indicator of battery condition.Delco has been using the "green eye" indicator for a very long time. It is nothing more the a small green ball that rises or drops depending on the specific gravity of the electrolyte (acid). It's a function of the state of charge of the battery.
The green ball is directly under a clear plastic tube that is pointed on the end. As the ball rises it gets closer to the pointed end of the tube and allows light to refract off of it making it very visible. Simple but ingenious.
