I always use the hidden OBC menu to track running car voltage and it shows 14.1-14.3V since the new alternator was installed 3 years ago. I do worry that if I do install the AGM and do NOT keep maintaining it every few weeks, via a tender, that this AGM may then tax the alternator too much to charge it back UP when driving and then I'm dealing with another alternator repair again...
Tho you DO have my curosity peaked about this...
