I purchased a new 2018 Leaf SV. Got a nice $11,500 discount and hopefully most of the $7500 tax credit next year.
It had 550 miles and was sitting in the lot for the past year or so.

My leafspy is saying SOH is 95.89%. Does this seem ok? i was expecting something in the 98-100 range for being new.

Also not sure the last time it was charged up to 100%. I drove it home at 97% SOC. So i'm wondering if i should charge it up to 100% to rebalance and see if my SOC goes up?
Please put your location in your profile.

Charging to 100% isn't usually necessary, and leaving the battery at 100% reduces life.

The first 5% loss is quicker than the later loss. The car loses capacity while sitting, especially if sitting at near 100% SOC.

SOC as read by LeafSpy is true SOC, and there is a top buffer, so 97% is expected.
Most everything around here is wet during the rainy season. And the rainy season is long.

So are you saying a 95% SOH is reasonable on a brand new 2018 Nissan Leaf with 550 miles?
I'm just concerned my SOH is low for a new 2018. Granted it has been sitting for several months at the dealer and i'm not sure if it was sitting on a 100% SOC.

That SOH is reasonable for a new 2018 Leaf bought in June of 2019.

PLEASE don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

The only simple solution is to discharge Leaf fully (till zero, killing the rest of energy by the heater) and then to use a pulse balance algorithm (available, for example, at any evtun.com charger).
In most cases, it helps, but the gain is not huge.
My father's car (2016, 30kWh) gained +2,8 SOH. Luckily one bar of SOH gain at the dash, so now there is 11.
Alcohol won't solve your problems. On the other hand, milk won't solve them either...
