Check the output voltage of the replacement alternator, especially if it is
an aftermarket one. Check cable and ground connections.

Slight dimming of lights is normal when idling because alternator does not
output so much energy. It should disapear after slight increase of RPM (more
than 1000).

So in other words, batteries are like milk.

Apart from the obvious difference that you don't drink what's in the
container, and that after six months unrefrigerated it is still ok.

Sorta - but you can't pour battery acid on your corn flakes.

Car batteries go bad just on time if nothing else. If you bought a
battery with a 60-month warranty and it's 60 months old, better get it
load-tested and think about changing it. Because it's thinking about
going bad - at the worst possible moment...

Milk goes bad quicker if it isn't refrigerated, batteries go bad if
you try to deep-cycle a regular starting battery, or you overcharge or
undercharge (bad alternator or voltage regulator), or you subject it
to wild temperature extremes regularly.

If it's sub-zero weather, better have the battery fully charged or
the acid gets weak, it'll freeze and crack the case.

That sounds good. The alternator doesn't put out it's full power
output at curb idle, an 80-Amp rated alternator might only put out 25
Amps if the engine is only turning 600 to 800 RPM.

The ignition, headlights, taillights, brake lights, heater fan and
radiator fan can easily draw more than 25 Amps. So if you are stopped
with the headlights and the heater fan on, you are running partially
off the battery and the system can drop into the 13V or even the 12V
range safely. As long as it picks back up to the 13.8 to 14.5 Volt
range when you start moving, it's fine.
