I didn't say anything about premature failures. Just that the battery will never be charged to it's capacity. If the AGM drops below 10.5vdc threshold then it may be irreversable.
Autoparts stores don't know everything. or understand specific vehicles quirks.
There is alot of disscusion about this on the web. Specifically Nissan, because they all seem to have same type of charging architecture.
The supposed rule of thumb is (usually), if the car came with Lead Acid Flooded, stick with that. Likewise for AGM. So the OEM dealers tell me.
I'm guessing you'll get FLA with new cars because they are cheaper and lighter than AGM.
I thoght there was a thread on this but it can be from another forum.
This is from Odysee:
A. If the battery is used in a starting application, the alternator should provide between 14.2 and 14.5 volts at the battery terminals. In cycling applications, the absorb voltage should be between 14.4 and 14.8 volts, while the float setting (if applicable) should be between 13.5 and 13.8 volts.
The problem is that the Nissan IPDM controls the amount of charge to the batter based on demand. Put a voltmeter on you r battery or observe through a OBD scanner how much the volatge will fluctuate at the battery whil ecar is running and varying the accessory load.
