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!
