I have used a battery charger with an appropriate lamp bulb inserted in
series
just to maintain charge when the battery has to sit dormant for some weeks.
A 12 volt automotive bulb insures that even if the battery has a dead short,
the charger current is limited. If you work out the Ohms law values, you
can
choose the bulb wattage to give a wide range of "tickler" currents.
It works, and not much could be cheaper.
The old trickle chargers put out about an amp and a half, IIRC, but that
could
be too much for long term storage.
I used to have a good circuit for a tapering charger which will completely
shut off
when the battery is fully charged. I haven't seen it around for a while,
and never
got around to building the thing because I never really needed it.
