I've done a hefty bit of google searches of this forum and youtube and in general and haven't stumbled across a how to for this yet.
Personally I've replaced the 12v in a Prius which I assume was harder to do (especially the part about crawling back to the hatch, finding the manual release lever, and actually getting the hatch to open, when the car wouldn't open or operate normally) but I'll be replacing the 12v in my Leaf in the next few days and thought it'd be nice to review someone's instructions and make it easier for others to find.
* Parts needed?
* Tools needed? (I used a 10mm socket, rachet, 1/4 to 3/8 adapter, some packing paper, and my hands)
* Safety concerns?
* Step by Step?
All the threads I've seen bounce around more about deciding if you need to do it or discussing the cost of going to a Lithium ion 12v replacement but none seem to cover the basics for a beginner or semi beginner to have a check list.
Bonus points if someone can point to a video of replacing a 12v in an actual Nissan Leaf.
edit: I've added Pics with notes further down.
The Carwings activation was inactive and the time on the car was Sunday at midnight instead of the current date/time. I had to set the time on the dash.
I did lose miles/kWh on the dash. Reset back to blank so I'll have fresh data.
I did NOT lose any significant settings, radio stations, window auto up, charge timers all remained.
I did have to connect to car wings once to get the carwings reactivated but it already knew the username and pw, so I just had to menu into carwings settings and tell it to sign in. Until doing that the charge timers were disabled but they came back on as soon as I activated carwings.
edit 2:
I had 10 DTCs before I replaced the old battery. Just swapping batteries cleared 9 of 10. I was unable to clear the 10th DTC immediately. I had to drive the car to work and then Leafspy Pro was able to clear the final DTC. The first and only time I needed the pro version, all because of a dead 12v battery. I'm going to say that means you'll likely need Leafspy Pro if you don't change your battery out before you start throwing DTCs.
