This video explains how a Variable Voltage control system (VVCS) works and why it can sometimes cause your battery to not get recharged properly. It also shows you where the IPDM is located and which wire to cut if you want to deactivate your VVCS. If your Infinity or Nissan battery goes dead frequently, this video is worth watching before you go buy a new battery or replace an alternator.

All the above have connector E13 pin 33 which is a red wire.
UPDATE 12/23/22: Since making this change, our battery that would typically go dead in about 6 weeks is no longer going dead. It has been working great!
