    "All batteries, regardless of their chemistry, will self-discharge. The rate of self-discharge for lead acid batteries depends on the storage or operating temperature. At a temperature of 80 degrees F. a lead acid battery will self-discharge at a rate of approximately 4% a week. A battery with a 125-amp hour rating would self-discharge at a rate of approximately five amps per week. Keeping this in mind if a 125 AH battery is stored for four months (16 weeks) winter without being charged, it will loose 80 amps of its 125-amp capacity. It will also have severe sulfation, which causes additional loss of capacity. Keep your batteries charged while not in use!"

    I learned a few things from this article, like: "Add water to your battery after it has been fully charged, never when the battery is partially discharged."

    I know, most of our bike batteries are closed and don't need water added.

    Living in the Denver area and w/ the area's dynamic changeable weather and temps seems I should be able to get out on average once a week or more for 30-40 mile runs, with the occasional longer stretch of 2-3 weeks where I won't want to get out to ride. I'm assuming I don't need to do much of anything, should I? I replace batteries every 3y regardless of their condition.

    FWIW, I've had motorcycle batteries last six years, in one case 6 2/3rds years.
