One experiment you could do is turn on all the appliances, excepting
heat or A/C (but fan, yes), and see what the instrument panel says the
power consumption is. I would guess you want the battery to sustain
that, or close to it.
This might be more accurately measured with an ODBII reader. I bought a
couple but couldn't get them to work with my Leaf...

Even a Yellow Top is the wrong battery for the job in your Leaf. It too
is optimized for engine starting. But it does have enough amphour
capacity to also support the large number of "always-on" computer loads
in modern cars that will run down the batter in a few weeks if you don't
have a high enough amphour capacity.
Lee HartIf 41 lead acid amp hours is adequate for a Leaf how many LiPO amp
hours do you need? If I knew how much a Leaf used daily I could calculate the
proper sized battery for as many months unused a Leaf has to endure. 20ah
should work for weeks. Since LiPO performs better than lead then a smaller
battery should work and could be sized for even a year however the smart thing
to do as with an ICE...simply use a battery tender or fully charge every few
weeks from external sources...maybe a little solar panel in the windshield some
Leafs have it built in. Lawrence Rhodes
