The tooling, machinery, personnel in the manufacturing plants, etc., etc., doesn’t just change overnight, with any mergers/acquisitions of the holding/parent company. :)

If/when/then - You don’t just throw away all that top level brand value you paid to acquire. :)

Those two are made by the same company. Who is also the oem Ford manufacturer.

You can’t simulate load on the bench, unless you shove a piece of wood into the gear…

Even with my volume all the way up I can’t hear it well at all, but multiple/rapid clicking is more of a symptom of low battery power / bad connection.

However, now that the starter is out, you absolutely should replace it, because it’s OEM regardless. Also, inspect the B+ cable and key+ wire at the starter, and replace any gaskets/bolts as per procedures.

2014 Altima, either the 2.5 or 3.5 is a flooded lead acid group size 35, with 550 CCA. No note 69 for AGM, no note 54 battery is vented to outside of vehicle. So yes, with a proper carbon pile load tester, that’s a bad battery.

I’m guessing that’s for an Interstate AGM MTX line, with an MSRP of 254.95. With tax, and/or installation, that’s right there. The MTP or MT line would be 640 and 550 CCA, $209.95 / $199.95 respectively, and you don’t have to have an AGM battery per OEM specs.

What is the voltage when it’s fluctuating?
