I'm sorry, but I'm having a problem with all the dialogue here.Just correct the problem with the drain and forget about it. If you have a pre CAN car, put a 1 ohm 10 watt resistor in series with the negative lead and slap a digital volt meter across it. If you read over .05 volts, keep pulling circuits until you drop below that. If you have a late 90s car with CAN, you may have a circuit that is not going to sleep. You need to find out which circuit that is. This battery brain thing is probably marketed in J.C. Whitney and all Slam Auto stores.
