IIRC, my local dealer charges $39 for the useless to the customer battery printout and check.
IIRC, there are reports that folks who didn't get the "required" annual battery check still were able to get their battery replaced under the capacity warranty. It may/may not help if something comes up in the future while within the battery warranty. From the '16 warranty booklet
MAINTENANCE , DATA ACCESS, AND
As a condition of this warranty, you are responsible for
properly using, maintaining and caring for your vehicle
as outlined in your OWNER’S MANUAL and your
NISSAN LEAF SERVICE & MAINTENANCE GUIDE,
and maintaining copies of all maintenance records &
receipts for review by Nissan. You are required to perform
annual EV Battery Usage Reports at intervals of
12 months, 24 months, 36 months, 48 months,
60 months, 72 months, and 84 months. These EV
Battery Usage Reports can be performed by a Nissan
LEAF certified dealer or any qualified repair shop facility.
The 12 and 24 month EV Battery Usage Report will be
performed at no charge to the customer, provided the
work is done at a Nissan LEAF certified dealer. Any
damage or failure resulting from a failure to have these
required services performed, or that could have been
avoided had these services been performed, is not
covered under warranty.
You are also required to provide consent to give Nissan
access to data stored on vehicle systems for the purpose
of vehicle diagnosis and repair. Failure to do so is
likely to result in denial of warranty coverage.
Evidence of the performance of the required maintenance
should be kept and presented as proof of such
maintenance in connection with related warranty repairs.
To assist you in maintaining appropriate records,
the maintenance log located in your NISSAN LEAF
SERVICE & MAINTENANCE GUIDE can be used along
with supporting repair invoices, receipts and other such
