Default Stupid car

For the past several months I have been having serious battery drain problems. The battery will drain in less than two days.

I had a yellow top Optima and several friends suggested that the yellow top might be the problem so I went with the red top and it still does the same thing.

I have disconnected the negative terminal and measured the draw between the negative cable and the negative battery terminal to be less than 10ma.

I have had the alternator checked and it tested perfectly with no faults.

The only thing that I have not checked yet is all the grounds to make sure they are all good. Which I intend to check tonight when I get home from work. But could one bad ground really cause the battery to die in less than two days?

I don't know what else to check, what else to do. Can anyone give any suggestions, help, direction?

Thanks,
Brian

Have you check that the system is charging? I mean, the alternator may have tested good. But that little source wire to tell the alternator to turn on when it's running?

I don't see a trickle charge killing either one of those batteries with that little draw.

Check the grounds for sure.
