I've heard of several people doing just this.

Second battery is smaller type feeding only second elec. ign..
It needs only to be able to feed the elec ign long enough for you to fly to
an alternate airport. I've heard of motorcycle type batteries being used.

Place a diode between the batteries so that the main battery can charge the
secondary but prevent the secondary from feeding back to the primary.
