i posted a couple of days ago about replacing a battery. After removing the 5 year old OEM battery I checked the voltage and it showed 12.1 volts. After driving a couple of days I checked the voltage on the new one and it read 12.3 volts. With the engine running it reads 13.8. I’ve always assumed that a fully charged battery should be at least 12.6 volts.
Could there be something wrong with my new Interstate battery?
