Most of my batteries last between four and six years (all in ICE vehicles). I had one anomoly, a Mazda Miata in which I replaced my AGM battery after NINE YEARS!! And it was still working but I figured, nah, it’s gotta die any day now. The battery used in the Miata was the very same size battery which was used in my BMW R1100R motorcycle.
Not sure if this is the exact battery mentioned in this thread for $150 dollars. Found it on Amazon for $115:
Shorai LifeP04, Power Sports Battery / 12V 10-14(Ah) 240 Cold Cranking Amps (CCA):

Here’s a Battery Tender model, which is larger capacity, $210 dollars:
Battery Tender BTL35A480C Lithium Iron Phosphate Battery / (12V, 26-35Ah, 480 ICA, 102.4 Watt Hrs.)
-- Caution: Quite a few reviewers report poor customer service from Battery Tender! --

To drive everyone just a bit crazier, here's what popped-up on Amazon for "lithium car battery"

Starts every day I've gone on vacation and left it for 10 days twice once plugged in and once not plugged in and neither time I had an issue starting up and driving to work the next morning. Was $110 on Amazon. Includes a BMS, over voltage protection, and low-voltage cutoff.
Keep spreading misinformation based on conjecture without any experience though
e: Holy crap this battery is down to $89 on Amazon clearance! Wow. Of course it's under $200 so it won't work, right guys?

You need to look carefully at the ratings. Those batteries are advertised as equivalent to certain AHr rating based upon CCA. In reality, they are only about 8 AHr or less actual capacity so they would likely be insufficient to power the residual loads in the LEAF while parked for a few days.
