you've also got to realize that most of the time when someone is advertising a product on here it is normally a spammer and normally they disappear via me. they are just pointing out the obvious and in all seriousness i would never leave my car hooked up to a trickle charger. if the battery cannot maintain itself (so long as the rest of the charging system is up to par) then you should not need it. if it sits for a while, sure (like my bike).
however, this post seems like it's copied and pasted straight from an advertisement or an informative post on a general automotive forum. that is the only reason we called you out like that. take it with a grain of salt, it is the internet afterall..
