What is a generally good battery show on the battery display? Since I bought my car my battery always read slightly above the red to slightly below half when driving. Battery was old and car wasn't driven alot before I bought it. Recently battery was dead had to jump it got a new battery no problems since but the gauge still reads slightly above the red at idle and goes up to slightly below half while driving. Is this normal seems a bit low to me.

Don't pay too much attention to the dash gauge, you would be better off sticking a volt meter on the battery with it running to see.
Batt gauge sucks. Use a meter
12V when car is off. 12V at idle, and 14V as soon as you go slightly above idle

You need 12.7 to start a car. Stock gauges are notoriously bad. invest in a decent DVM and measure the battery output with the car off, at idle and around 1500pm.
I like my old in-dash amp meter. Only thing it's good for is telling you whether the battery is charging or discharging. You really need a volt meter know what's going on.
I could say the same for folks who have only a volt meter. I like the combination.
