Colorado. Why AGM for Leaf? Don't need the cranking amps, still heavy, more expensive and only twice the life of lead acid, to name a few reasons.
I totally agree! What's with this continued obsessiveness about replacing the Leaf's battery? It's a waste of money,
my OEM 2013 Leaf battery lasted over 7 years. It's replacement was $110. Most data reported about the need for
a Leaf battery replacement are just anecdotal! Few if any longitudinal data have been reported. Some complain
about the Leaf's low charging voltage, and then recommend an AGM which requires a higher charging voltage than
a typical flooded lead acid battery.
Well, batteries can die suddenly, and this may result in somebody getting stranded in a random place.
There is nothing wrong with upgrading a battery, even before its' death, and if there is clearly a better solution, I would go for it regardless how fresh my flooded lead acid factory battery is. Alas this is the issue, there is no silver bullet out there at this time, while LiFePO4 seems very promising and exciting, the need for BMS tampers that. I also think the self-heating solutions are in their infancy, given a few years they may become more robust and mainstream, along with better prices.
I may actually opt for an AGM after all at this time, as I can foresee it lasting for quite a while, and with the winter coming, might just as well bite the bullet now.
The weight is similar, but there are pluses in that these are more resistant to shaking (I always hated that about flooded lead acid), and the price is not exorbitant. I've done a few mods to my Leaf already (horn, internal/external LEDs including yellow fogs, trunk organizer, rear seat cup holder, 3D mats), why not the 12V battery
