Batteries can go bad in a hurry, I lost a brand new (five months old)
starting battery in the middle of a trip back in September.
But, if the battery is dropping to about 12.35 and then staying there you
may not have a problem.  And as for the LED indicators, the circuit that
drives them has an adjustment and might not be exactly up to snuff.  I have
no idea how to adjust it, I just recall discussion here on the list about
it.  Maybe check the archives?
