If this isn't OPs question then my bad lol. I guess I was understanding it wrong. And if I'm mixing up what I have with a charger then my mistake again lol

The issue is that when programming, the ECM requires precise voltage or it will stop programming. Most battery chargers or tenders will not provide a stable amount of voltage. For lengthy programming, it's not safe to use anything but a voltage stabilizer.
