AOK.
No-load terminal voltage for a car battery is 13.2V, which you'll only see for a short while after stopping charging and disconnecting everything. Are typically charged around 14V. With a slight load (i.e. clock & battery leakage current), 12.4V is about right for sitting overnight. Might see a few tenths higher in summer due to warmer.
