Re: Battery Charging Voltage
Dave, Sounds to me like a normal reading. That's what my TJ"s
voltmeter reads. And, it's always a good idea to clean the terminals
every year (before winter sets in). I use a foam battery cleaner in a
can and a battery terminal sealer, also in a spray can. After I use
the cleaner I use a battery post/cable wire brush then reconnect the
battery cables and spray with the sealer....Works for me !

Re: Battery Charging Voltage
An easy way to check battery health is with a voltage load test.
If you find that your battery voltage goes from high to low (relative term)
then odds are it's not handling a charge very well and is bleeding off quite
well.
If you throw a battery on a charger and then measure the voltage you'll
measure a 'skin' charge (or surface charge) that will be equivalent to the
charging voltage.
You need to load the battery to bleed this off. I use an automotive
lightbulb (12V/40W) for 1 minute and then I measure the voltage again.
Being that the charging voltage is around 14.5Volts, if I measure after
bleeding and find a voltage less than 13V then I get worried.
A battery with only 12.1 volts is considered to only have 50% charge left in
it (this is amp capacity it's referring to).
I may have gotten my terms back to front...(and am not entirely sure of the
bulb wattage) but this is a good rough method to determine your battery
health.
