Battery health estimate
Frequently asked questions
How is EV battery health estimated?
A practical estimate divides current full-charge range by original full-charge range and converts the result to a percentage.
Does this replace a service report?
No. Temperature, tires, software and driving conditions can affect range, so this is only a quick estimate.
