1. I believe the failure mechanism on lead acid storage batteries is
largely a matter of charge/discharge cycles so long life from a seldom
used battery is not surprising. Capacity also drops with use if the
cells don't short out first. AFAIK the lead plates break down
creating sediment that collects in the bottom.
2. The battery/alternator tie in would be if the regulator let the
alternator overcharge the battery to failure where it shorted and took
out the alternator diodes. Ditto if the battery shorted and cooked
the alternator. The bottom line is that it pays to check both but you
may not need both. It depends on what failed in the alternator.
Before regulators were incorporated in the alternator it was
reasonable to replace the regulator and alternator/generator as a
pair.

Didn't mean to be confusing. That truck and that battery used to be a daily
driver until recently. Now it doesn't see the daily use, but the battery
was subject to normal rigors for years.

No disagreement with that. My original comment was in response to a poster
who suggested replacing both as a matter of course if the battery was over 2
years old.

As it was all to common to have to replace just the regulator. They used to
"stick" and soak the battery overnight.

Re: 1998 hyundai accent, wont hold charge
You should have two powers into the alternator at the plug and charging
voltage out at the main terminal. If you don't have power at those two
wires, your alternator will not charge. If there's a problem in the
charging wire between the alternator and battery, it will not charge. You
should probably do some poking around with a voltmeter.

That's true. I'm curious whether you ever check the fluid levels in your
batteries? It seems that few people ever do, but batteries need to have
water replenished just as much these days as they ever did, regardless
of the bogus "maintenance free" labels manufacturers paste on them. Call
me cynical, but this seems to be nothing more than a tactic to ensure
that batteries rarely last more than three years.

Multiple clicks generally indicate a weak battery. No sound could
indicate a dead battery or starter, depending on whether anything else
electrical worked or not (lights, radio, etc.). If they do, it's
probably not the battery.

That's not true. The alternator produces electricity whenever the engine
is running, just less amperage at idle than at higher revs.
