You can probably go lower complexity than that. Assume 5 minutes of
charging per day at 500mA. That would be 0.05 amp-hours per day, or around
2 mA continuously.
Assume you have a 20V DC wall wart lying around from an old
somethingorother. Or assume you have an AC wall wart and can invest in a
suitable diode (<$1).
http://en.wikipedia.org/wiki/Wall_wart
A 20V DC wall wart and a 5K resistor, left connected continuously, would
probably be fine.
And if you want to think a little harder and are willing to spend the big
bucks (maybe $4 at Radio Shack for a bridge rectifier), you can probably get
rid of the wall wart. (But once you do that, a fuse and a metal box are the
safest bet, which all told could drive the cost up to maybe $20 at Radio
Shack prices.)

Face facts. Motorcycling simply is not the sport for someone like you.
Take up blogging or something without expensive problems.

This an _ad hominem_ comment. Ad hominem means a remark addressed
"to the man" personally rather than to the issue.
If you must post personal comments about Bryan, please make them
non-confrontational and respectful, such as asking if he has multiple
wives or whether members of his family were among the Mormons who
attacked a US Army wagon train in 1857.

That's curious; I left my Suzuki S40's key on for a few hours
until there was no ignition light and then charged it up and now
it seems to work fine.

I think how tolerant a battery is to total discharge depends upon the
battery. It's been awhile since I read about it, but I think one of
the traits of a Deep Cycle type battery is that it is more tolerant of
sever discharge than a standard battery.
I used so many "thinks" that I decided I should Google something up.
