Range isn't that accurate an indicator of battery health. With the same car one person may go 80 miles and another only 40 with the same battery depending on their climate, route, and driving habits. For example - when I bought my Bolt somehow the previous owner had only averaged 1.4 miles / kWh over the first 30,000 miles of ownership. I have averaged 4.0 mi/kWh over the 21,000 miles I have owned it)
You need to check the remaining capacity of the battery. A crude way of doing that is charging it fully and seeing how many bars remain on the gauge. Much more info can be obtained with a cheap OBDII dongle and a free app. This link should have the info you need
