12.4 V is on the low side in my book. I would check the voltage on this battery monthly. I have gotten up to 7 years with a factory battery on GM cars, but I average 5 years across all brands. I don't think your battery will make it to 5 years.

BlueinTN, I would be worried with 12.2 V after sitting for 2 weeks.
