The charger says it's running at about 3 amps. When can I consider the
battery properly charged?

Lead-acid batteries are best left being trickle charged. Of course
that implies that the charger is capable of doing that, which many
cheap ones are not.


Ouch no!! That's the best way of wrecking a lead acid battery, especially
if the sealed types. Any current after it's fully charged will dry out a
battery.

The best charger has always been a constant voltage charger. This matter
has been discussed ad nauseum before in the NG.
