Good to talk to you all. Its been a long time since I wrote here last time. sorry for my english, not a native english speaker. hopefully, you will understand what i mean 
Anyways, I don't seem to ride the 800 as often as I used to. but i don't like the idea of removing the battery so i came up with this setup to charge the battery every so often through the cigarette lighter socket.
Well, to cut the long story short, some of you will probably laugh at me, but that is fine as long as I hear some of your opinions
I went and bought a motorcycle charger (SM-1236 by Deca-weld (i think italy) which comes with conventional red and black clamps for connecting to battery terminals. I modified the connections of the charger so that now the charger connects directly to the F800GS cigarette lighter adapter. the connection was made professionally and tested for continuity etc. all was ok. so I feel good about that part. But i haven't actually tried charging yet.
My question is, is this a good idea? I mean, is it going to do the job?
The charger I'm intending to use basically has 2 charging modes: Mode 1: 0.8 Amps, Mode 2: 3.6 Amps.
So, the big question is: will it actually work through the cigarette lighter socket on F800GS? I mean, do I need to keep the ignition on?? etc. or is the cigarette lighter socket live with the ignition switched off?
