[Shop-talk] Trickle Chargers

Another option for batteries that run down due to constant drain from the
vehicle is to add a battery disconnect switch.  It can be a simple and
inexpensive switch that you add on the battery post or a more sophisticated
one like the ones made by Battery Brain. (www.batterybrain.com)

I use the remote control models of the Battery Brain on antique cars that are
not driven regularly.  It comes with a remote key fob with a single button to
wirelessly disconnect the battery or turn it back on.  This device has the
added benefit of foiling a thief.  On modern cars, a disadvantage of a
disconnecting the battery is the fact that you lose any settings that require
a constant voltage, such as clock settings and radio station presets.
