 Do the math.
 
 5 mA.= 1/200 of an amp.  Typical battery is 60 amp hours.
 
 60 / 1/200 = 12000 hours = 500 days for the radio to flatten the battery.
 
 Look elsewhere, like self discharge in the battery.  A battery left
 for more than a couple of weeks should be on a smart trickle charger.
 500 days is a heluva lot more than a couple of weeks.

 Why does the above draw 5 ma when turned off? Had this sucker hooked up
 direct to the batt and over several months, it drained the it.

 Do the math's properly!
 5ma is 59390hrs from a 60Ah battery with Peukert exponent applied,
 2474 days, 6.77 years.
 However obviously internal losses will flatten the battery much
 earlier!
