The simplest solution to your battery problem would be to disconnect
the battery from the rest of the car and charge it in isolation.  Hook
it up when you want to go somewhere.  Unless the deep discharges have
damaged your battery this should solve the stated problem.

That would give you time to discover what switches/shorts/seat heaters
or whatever are drawing down your battery so fast.   But see below for
the possibility that your battery cannot hold a charge any more.   A
battery in good condition  should be able to go for at least a month
of idleness and start your car -- even without the pulse charger doing
its thing.

  A trickle charger isn't going to quickly charge up a battery that is
discharged to about 1 volt per cell (or one or two shorted cells?) as
you report your battery to have been.  Your battery may need
replacing; there may be no excessive drain on the battery.  Your
alternator might deserve a checking, too.
