1. A battery confirmation method for confirming a state of charge in a vehicle battery installed in a vehicle, comprising:
- connecting a tester to an onboard diagnostics connector of the vehicle;
obtaining an electrical load measurement representative of an electrical load on the battery from a controller of the vehicle through the onboard diagnostics connector;
obtaining a vehicle operating voltage from the onboard diagnostics connector only when the electrical load of the battery is within a predetermined load range wherein the vehicle operating voltage is a vehicle operating voltage measurement obtained through the onboard diagnostics connector from the controller, anddetermining a state of charge (SOC) value based on the vehicle operating voltage.

Abstract
A battery confirmation system and method for confirming a state of charge in a vehicle battery installed in a vehicle includes a vehicle having a controller, a battery powering the controller, and an onboard diagnostics connector operatively connected to the controller. A tester is connectable to the onboard diagnostics connector. The tester is configured to receive a vehicle operating voltage from the connector when an electrical load on the battery is within a predetermined load range and to determine a SOC value based on the vehicle operating voltage.
