I would think the TESLA Powerwall would be a better choice than trying to create a home battery back-up unit with an old Leaf pack. JMHO.
Tesla's
powerwall is far too expensive to be practical.
It would actually be much cheaper to buy a
NEW LEAF pack (assuming Nissan would sell you one) at ~$6,500 per ~21.5 kWh available than a powerwall, at $3k per each ~7 kWh available module.

My minimum-lenght trip is 50-55 miles with ~1500 ft of net descent, with the same ~1500 ft of net ascent on the return, requiring ~10 kWh from the pack in Summer, and ~12-14 kWh in the Winter.
So I don't think I will want to rely on my OE pack, once it is down to ~16 kWh available (Winter) from"100%" to turtle, which now looks likely to occur by ~2019.
I knew ~all this when I bought my LEAF, but also counted on the option of keeping my used battery, when and if I ever bought a replacement.
I wouldn't mind returning my pack to Nissan, as long as they paid a reasonable trade-in value, for packs with a lot of use left in them.
The $1,000 core charge means Nissan would essentially be offering me ~ $62.50 per each of the ~16 available kWh, in my used pack.
Sounds to me like a great deal...
for Nissan.
In any case, any future battery problem I may have with Nissan is probably years away, and any number of other circumstances could intervene prior to then, rendering the question moot.
So I'm not suffering with this, or any other
battery-related anxiety.
