Horn Swap & Batt.

I'm thinkn of changing out my horn and have a couple questions.
How loud is the stock horn in db, what is the power draw?
I want to do a direct swap and have found a 115db horn that draws only 3amps, I think it should be a easy swap and allow me to use the stock switch.

I just have to put my 09 on a charger for the 1st time, cold weather I think and sitting two weeks did not help.
Anyway, looking at the book it says only charge at a 1.5 amp rate. This does not make sense to me, what does the stock Alt. put out, 100w 9amps? I know lots of ele. crap sucks up some of that 100w but I find it hard to believe only 18-20w are left for the batt. to charge. Does anyone really know what the safe max rate is for the batt, at what rate does it charge when running?

BTW iF anyone is interested Amazon has a decent price on a 6/12v 2amp charger with a included 12v plug, batt. rings, and clips, <$28.00

No idea about the horn but as far as a charger is concerned I would just get an optimate or a battery tender. It will keep the battery charged and make it last longer. Just hook it up when your not riding and don't have to think about dead batteries again. Just a little peace of mind.
