I have three red tops. One's in the GN that I drive 5-10 miles every week or two. Sometimes a month between drives. Had it four years with no trickle or any other charge and so far no problems. Put one in my son's truck right after putting one in the GN. It also drives an amp-subwoofer system. Once, he left the lights on all day and drained it. Jumped it off and alternator-charged it with no problems. The other's in my daily driven truck and had zero problems. I know others who've had nothing but bad luck with their's. All batteries have a failure rate so I likey just got lucky with my three. I bought them because they look cool, theres no maintenance or acid corrosion issues, and - if lucky, they'll outlast conventionals.
