HELP! 2004 supercharged XJR 4.2L

Thx for the reply.
Very interesting. I accept your explanations, you're right on voltage vs current for charging and probably on AGM requirements and ECM (I was not aware).
However...
When I go to the Varta site and look for what should I put on a X350 4.2 SC, they offer Silver Dynamic and Blue Dynamic models (which, I understand, are silver calcium technology unless I am wrong) but also Silver Dynamic AGM, which is AGM technology, which should not be ideal wrt ECM:
Search | VARTA
In Europe, X350s were delivered with Varta batteries, so we may guess Varta knows what a X350 4.2 SC ECM may accept. Or not?
