You simply need one of the readily available trickle chargers with the
computerized circuit that checks the battery voltage and only turns on the
charger when the voltage drops to a certain level. ****sche and others
make
one that plugs into your cigarette lighter. (Obviously...the ****sche logo
makes that one more expensive than "generic" models.). You should be able
to find one for $35-50.
If your storage garage does not have power, then you will simply have to
take the battery with you...even though it's a pain. (Hint: If the only
power is an overhead light...of the standard screw in type, then consider
installing in one of those screw-in adapters that offers a couple of
electric sockets, plus a bulb socket...and usually a chain on/off switch.)
