The strategy is/was as follows:
1. I scheduled a battery test with Mark Mitsubishi after giving them both of the EvBatMon readings.
2. Today, they did the wrong test (the "cell smoothing" test instead of a "capacity" test), see this topic: viewtopic.php?f=23&t=2386
. Then the service manager said to call Mitsubishi service as they couldn't do what I requested. They did not charge me for the battery "cell smoothing" test. (Forum members perhaps should note this if they request a capacity test and the dealership does the cell smoothing test). After the cell smoothing test the RR on our car showed 66 miles.
3. I called the Mitsubishi service folks and have opened a case, the notion being that with 22% degradation, I have a warranty claim under the 10 year warranty and pages I-4, 5 of the manual as the battery is less than 2.5 years old.
As an aside, we were given an i-Miev loaner. It was a 2012 i-Miev (JA3215H17CU022346) with no quick charge, a battery that was 3 months younger than ours and 18k miles. After taking the battery to one bar and recharging, the RR showed 52 miles. EvBatMon shows (32% degradation):
I emailed this info to the service manager.
To be continued.
