Re: Charging on a timer ?
if you get a battery tender/ battery tender jr/ yuasa charger, they all have smart technology that won't over-charge (in other words, they will condition the battery, keep it charged, but not over-charge the battery--you can leave the charger on for literally months, or theoretically years at a time with no harm).
If you were to set it on a timer, assuming you mean "on one day a week" as opposed to "on for a couple hours a day," all you'd be doing is letting the battery drain (although just a TINY bit) between re-conditioning/re-charging.
Get one of the above, plug it in, forget it--lots of people do that for 4-5 months over the winter if they live in northern climates anyway. Once the battery is fully charged, it's probably half a penny a day if that to keep the thing running.
