2013 won't start after low 12V battery event

[cwerdna]

Is there a URL somewhere to a version of the LeafSpy Help screen that I can look at on my laptop? A quick search didn't turn it up.

There are directions at the top of the help on how to email the author for a PDF of the help file.

could I see if I could find a mobile mechanic who has a LeafSpy or some other kind of tool that could do essentially the same job?

I think the car will start and drive once the 12V battery is replaced. After that you can decide how to proceed. I'd suggest getting LeafSpyPro for yourself, it will cost about $30 in total and is well worth it, IMHO. The codes may reset by themselves but if not I'd guess most mechanics with an OBDII tool could reset them although some codes seem to be more persistent and might require several passes to clear completely. Finally, consider getting an AGM style battery since they are better suited to the needs of a Leaf (no starter motor and no alternator). BTW, a Leaf uses a 51R group size battery.

To directly answer the question: you can replace the battery yourself, if you have enough experience to do so with a normal car. It's virtually the same as with a modern ICE car. Be careful with the positive terminal and cable.
