Nissan Leaf Battery Flattening Test

Post by 4Springs »

Has anyone had their Nissan dealer recommend that they flatten their battery on a routine basis?
A member has had this advice, that he should run the car almost flat, then turn on the heater flat-out until the car completely dies. Then charge it up again, and repeat a couple of times over the following week.

Does this sound like a thing? Or just a dealer hearing something somewhere and applying it to a Leaf?

I think it's worth doing but only to gauge capacity loss over time. Perhaps not turtle the thing...

Given the nature of Li batteries, I would have thought this would be a bad thing to do on a regular basis.
Maybe very,very rarely to see the State of Health (SOH).

My dealer didn't give that advise.

Although I did notice my SoH increased very, very slightly (around 1%) when I did test to flat, but it quickly revert to normal. See the spike in Feb early this year on mine (ignore other spikes):
