I have been driving my R4EV for 11 years, it has 105K miles on it. The battery has never been "extended charged". On most days when I wake up and unplug it, the range meter says between 95 and 102 miles - it depends on weather and how aggressive I've been driving. However, for the last 2 days it suddenly shows only 74 miles range - though it still shows the battery as fully charged.
I'm relatively certain I didn't lose 20 miles of battery capacity overnight, and it's just a matter of the meter being confused. Has this happened to others? Any idea how to fix it? I was planning on just driving it normally and letting the meter sort itself out, but that might be unpleasant if it goes into reduced power mode 20 miles earlier than it needs to.
 
Do a simple Tony test and you will know the actual SOH of your car battery.

or only with TDS soft
