My battery only has 12.1 volts sitting still, running my alt keeps it about 14.3 and a little less with all lights on... Should I get a new battery before making the 1700 mile round trip to nxm ?
Well not to scare you or anything but 3 years is the normal age for a car battery to go kaput....it might still last you awhile longer but don't be surprised if you have to get jumped soon. My vote would be to buy a spare one and take it to nxm just to be safe.
Not ragging on you but I sell batteries for a living. 3 years is a short life. I would say the average life is 5 years but typically they last longer than that. 12.1 volts just means your battery is discharged. Technically speaking 12.0 volts is 0% charged and 12.77 is 100% charged. Your alternator will not charge the battery from that low, hook it up to a battery charger over night then take it in to get load tested. Not tested with an electronic tester but an actual load tester-they are much more accurate.
