As you know in October 2019 to start erasing some of my EV ignorance I bought a 2016 Nissan Leaf SL with a dying traction battery pack after 22K miles.
The 107 miles EPA range was down to 60 miles. This helped me to learn about the subject of range anxiety since I live 15-25 miles from my 3 Walmart options.
I am 50 miles from a fast DC charger but I risked that it would be working. Only one fast charge a day is suggested per day because of overheating the battery.
The Nissan dealership assured me I would be triggering a new battery warranty soon. That happened 35 days after I got the car home. After some pushback I started to researching and learned that Nissan was all the ropes financially speaking and predicted to be in bankruptcy by 2022 by the fired CEO. Due a Covid-19 bail out and loans from Japan the bankruptcy can has been kicked down the road I expect.
Six weeks after I trailered it 75 miles to the nearest Nissan Leaf certified dealership I got a call the battery had come in. 20 minutes later I got a call back that the car was ready for me to pick up because the 30 kWh battery had been replaced with a new 40 kWh
$13,000 (per Nissan) battery at no cost to me.
So my driving range jumped from 60 miles to 150 miles. Nine months later a guy ran a red light in a Toyota van injuring my wife and daughter. While he totaled our Leaf he landed on his rooftop sliding to a stop when it hit the curb down the road.
EVs I have learned never run empty like a gas tank. When our Leaf warns Low Range it can pop up a list of charging stations and offer directions while you still have 15-20 miles of actual range. For bull headed redneck's that plow ahead Very Low Battery displays.
About 6 miles later the computer pops up a

icon (think Limp mode). I have seen it once coming up the steep Hill to the house. Since I was 300 feet from the charger I didn't test the range to Drop Dead. For some reason after I powered down I restarted the computer and the turtle was gone. Keep it mind when my 400 volt battery reports dead it's still contains 350 DC volts.
Consider buying a sub $14K EV for your own EV crash course.
