How about for a low amperage charger, say 2 to 5 amps?
Can I use a battery maintainer/tender without disconnecting the battery? I'm going into my 1st New England winter with this car and its already cranking slowly.

That is referring to when higher amperage commercial chargers are in use (a good shop charger can put out between 30 and 200 amps, which can fry the voltage regulator or diodes in the alternator). Good quality battery maintainers are under 5 amps, and usually are only running at a fraction of one amp. We store cars over the winter for some customers using very good maintainers, and never disconnect the batteries.
