The chart that you referenced is clearly marked for a 100% capacity. That's not you. There are other charts, like these one. You need to be below 66% to win the new battery.


Use this 75% chart for a battery that has 10 of 12 capacity bar segments.

Use this 69% chart for a battery that has 9 of 12 capacity bar segments.

Use this 63% chart for a battery that has 8 of 12 capacity bar segments.

Sorry, I was misinterpreting. Thanks for setting me straight.

You're confusing Status of Charge Bars and Capacity Bars.

The range chart has nothing to do with Capacity Bars.

It is using Status of Charge bars.

There is NO correlation between the two.

Tony, were you off by a cell? In your .jpg version for 24 kWh Leafs, you list 60 mph as being 3.9 miles/kWh and 82 miles. 1.262 * 82 = 103.484, but that was for 60 mph, not 65 mph.

3.9 miles/kWh doesn't sound right for 65 mph.

The original chart was purposely conservative.

The LEAF will do 4.0 at 65mph with the original Bridgestone tires, and only a little less (3.9) with the Michelins.

Ok, gotcha. It had looked like you were off by a cell.

Tony,

What does "controlling" mean, in the sentence

'The Mile/kWh value in red below is controlling, NOT speed'

Indeed we are much better off now. My rule of thumb while driving was to assign 7 miles per bar if I drove carefully, or 5 miles per bar on the interstate. I also used the hrs:mins to full charge at 120v on the dash to predict when a bar was about to go out and should therefore not be counted into my DTE estimate.

Now a quick glance at LEAFspy pro is all that's needed.
