dash voltmeter indication - charging well? 200

I installed a voltmeter with tack and clock many months ago. All works well.

As far as I've always noticed, the voltmeter is always a hairline below the red, I guess around 14.5 volts.

Around two weeks ago, when I startup the car to idle, without throttle, the voltmeter reads exact 12 o'clock, I guess around 12 volts. If I throttle, after 2-3 seconds it goes up to the usual 14.5. During driving it always stays at 14.5.

Is this indicative of a dying battery? Could it be the charging system not being effective? Should I replace the alt brushes (is it simple, never touched that)? Anything else?

BTW, my idle is always steady at around 600 rpm. The car is very well maintained by me, no issues, no poor history, relatively a virgin except for key maintanance.

Advice?

Thanks,
