2 high voltage connections versus the 1 for 11/12, but I think the under panels would have to be pulled
to view. Any way if you can't have access then neither method will work.
My 2013 S was manufactured in August 2013 and has only 3 sensors showing in LeafSpy, and I have heard good things happened to battery tech as 2013 production ramped up in the USA, so I'm hoping that my battery is from after some sort of generational change (for the better). It sounds like there have been 3 generations of battery, and I'd like to collect the definitive "how to tell what battery you have" in one place.
Seems like the Generations of battery ID'd so far are (where batteries from any "whole" generation are interchangeable):
Gen 1.0 25kWh Japan 2011/2012/Early 2013: 4 temp sensors in Leaf Spy
Gen 1.5 25kwh USA Fall 2013 "Early Lizard?"...3 temp sensors in Leaf Spy (?)
Gen 2.0 30kWh 2016
I've searched and searched this forum for "how tell lizard" and I can't find any reference to
- Why it is called Lizard
- If there are any visual differences you can see by peeking under your car (can you see the mounting bracket differences?)
- If there is agreement on the meaning of 3 temp sensors (Leaf Spy says I have sensors 1, 2, and 4)
- When the VIN number or production-month breaks are for the USA transition in battery types (I'm 414434 / August)
