Update: After driving my car as normal for a week, I was curious if the battery was holding. I checked it yesterday morning before driving it. Still at 12.62 volts while connected to the car (which drops the volt reading by .2v +/-). So I checked it disconnected and got 12.81v (sweet). I then put it on my Bateryminder 128cec1 for 24 hours to see if that would maximize the battery further and it did. New reading disconnected from the car 13.05v (after 6 hours rest). 12.81 connected to the car. Also, prior to my first post here, internal resistance was at 3.21mΩ. Now it has dropped to 3.02mΩ. So the battery is growing younger and heathier.
I also found a used Batteryminder 12248 on ebay. I will use that on my non Odyssey batteries, even though it is/was approved by Odyssey, I like the false sense of security I feel because the 128cec1 has the Odyssey/PLT mode. Every other weekend, I will hit each Mercedes overnight with a Batteryminder. The Landcruiser will have one on it basically 24/7, since I only drive that a couple hundred miles a month, the current gas prices are terrifying and will certainly get worse.
