If your battery is good it will easily go a couple months with out charging it,The most wear on an engine is at start up its not good to start it up all the time unless your going to ride it.

A good battery will probably go 3 months w/o charging and still start the bike. But that doesn't mean that practice is best for battery longivity, because in even a months time it has discharged enough that it is slowly deteriorating thru the process of sulfation. I have proven several times that lead acid batteries can last 10+ years if they stay fully charged, except when actually using them. But if you think that the price of a battery every few years, is worth not hassling a float charger staying connected during non use, that is quite understandable. But the fact (experts agree) still remains, any battery that stays full charge most the time, will have much better longivity. For myself, connecting a float charger is no harder than hanging up my helment. But my OEM battery,...at 3 yrs old is very weak, probably because of the way is was treated before I got the bike 6 months ago,... but I can probably get another year out of it, just by keeping it fully charged, and maybe just for the challenge of it all

Bill,
You have made it quite clear many times that your battery is some kind of super power, or ???

But the fact is, many.....if not most here have battery problems if not charged every month or 3, especially in colder weather, when our rides are maybe shorter, and the bike's charging system is not keeping up w/ the discharge from frequent starting, because of the shorter rides, etc etc.

I just try to figure out the point of you're several posts that always seem to follow mine as if to counterdict what I post about batteries,.....only to help those that have problems better understand the importance of keeping batteries full charged for the longest service life.
If you are just commenting that your battery......or charging system never needs charging, fine. But if you are trying to convince that all the rest of us never need to charge our batteries in a month or 2, you are only hurting them, not helping.

 Sorry my battery must be a super power battery,But I must luck out because the 16 or so bikes in the last 38 years must have been super power batteries.My brother started when I did he had the super powered batteries too. The more you play around with a battery the shorter the life is.

  Its a 2006,bought in 2007 new. How old is the battery? If your battery is weak at 3 years old you must be doing something wrong.

Most of my rides are maybe 40-50 miles about every other day,I keep it in a dry garage never gets below 32 in the coldest of winter.I've only put water in it one time 2 years ago.When I put distilled water in it I charge it at 2 amps,Then put the charger on 8 amps and let it boil for 5 minutes,I think that cleans the plates off.

  I got a feeling he had a battery tender on it,That will do it in.
