I found prices for the Valence Battery on Energy Bay - the 40 amp is $699.

hey Nerys,

So the leaf is known, at least the 2012 and older models, for not being very good at looking after and charging the 12v battery. I figured that out after having all sorts of issues with my 2012 leaf and they were resolved with a new battery and I've changed how I behave.. I now don't just plug in my car anytime I'm home as this pulls juice from the 12v all the time to keep the car charging system ready even if it's not charging. I also plug it in to a battery tender every few weeks. My 12v battery was replaced after 3 years.. but I hope that my new behavior will allow this replacement battery to last a little longer.. more like 7 yrs and getting closer to your average you mentioned. Most ICE cars are good at looking after 12v batteries and it's so strange that nissan didn't make the leaf be just as good.

i think that is what the other posters are saying and why they are asking about your location.. I'm Utah and the winters are cold and long enough to stress out a poorly maintained 12v battery.

My batteries last ten plus years what other options would I need to look for?

I have yet to have to replace a battery because it wore out the only thing that has ever killed a battery for me is neglect on my part.

if I ever have to replace the 12 volt battery in my leaf, ever, short of neglect, I would consider it defective.

Now the lithium battery that's pissing me off I am well below 70% capacity but it won't drop the third bar somehow I think it's programming.

I should start checking my 12 volt battery to see if anything might have improved as far as maintaining a more optimal resting voltage while connected to the car. As far as batteries lasting, I have also seen several in my area go 8-10 years or more but I am in a unique area that is vastly different that most of the US.
