OOPS!Len did say 1.5W which would be on the order of ~125mA.

You're correct - it isn't. A 10 ohm load at a battery voltage of 12.6 volts would draw 1.26 amps, but when the voltage drops to, let's say 11.5 volts, that same 10 ohm load would only draw 1.15 amps; the change of the state of charge is definitely time dependent.Also, the time to discharge to any given level isn't necessarily a linear function of the load.
Ned said:I still think you're in the range of self discharge. A 220AH battery has 2640W of power at full charge. If it self discharges at 3%/month that's 2.64W/day, more than you're seeing.

I have removed all 12v fuses except for the circuit that has the radio on it. I have watched the voltage drop for about 64 hours so far. For what ever reason the radio does appear to be consuming 1.0w to 1.5w per hour in the "off" mode. Thinks thats high but that is what it is.
