Welcome. Yes, there is a starting type 12 volt battery in the Leaf, along with most other EVs. If there is an outlet nearby, your best option is to connect a 12 volt external battery maintainer, leaving the battery installed in the car and connected.

I ran mine one Summer, and at least in a gentle use case, they hold up fine.

It can be considered to be a design flaw to have the 12 volt battery, which is needed to start the car, remain a critical component while driving.

I had to update LeafSpy Pro to get rid of the quirk. IIRC, the quick setting change is changing kilometers to miles.

People have installed lithium iron (LiFePO4) batteries, with good results, in warmer climates. Most replacements, though, if they aren't OEM type flooded cell batteries, are AGM type, which work better in the Leaf than the OEM.

This sounds like one or more cells in the battery are going South. You need to use LeafSpy Pro to get a depiction of the battery cells and the voltage variations between them. Hawaii is kind of deceptive, in that while you don't usually get extreme heat, the generally warm/very warm nights prevent t...

What's happening is that Nissan, claiming to be short on 40kwh packs, is offering to buy the cars back. There is negotiation involved, so if they offer that, don't accept their first $ offer as their final one.

Toyota is also working on the solid state batteries. It makes me wonder if this is the Hydrogen Stalling Tactic in another guise...

For that kind of draw, I'd go to a fused connection directly to the 12 volt battery.

I think that the second gasket is actually different more than damaged. I'll get to posting a photo of them sometime this week...
