About using a timer..., if I use a timer and the timer turns off the
power to the battery charger when the time is up, the battery
charger will still be set to "ON" and it will still be connected to
the battery. Is there any problem with that?

Never saw a problem with the charger I used. I very much doubt any
dumb charger has any difference from it being off and no power to the
charger.

Now, I'm getting curious, so I tried a Google search on this question. Not
too much info so far, but here's what I did:

I did a Google search for "leaving an unplugged battery charger connected to
battery" (without the quotation marks). One of the results was this:

It says,

"To remove the battery charger after the charging has been completed, unplug
the charger
from the power outlet before removing the terminal lugs or connector from
the battery.

Remove the terminal lugs from the battery terminals immediately. Do not
leave a fully

charged battery connected to an unplugged battery charger. In some
instances, the

charger will drain the battery through the power transformer."
