DEFINITION: This Symptom Diagnosis Table tests a charged battery's capability to produce current. Do not perform this test unless a green dot is indicated at the battery hydrometer. Also, do not perform this test on a battery that has been frozen or otherwise damaged.

1. Access and store any Diagnostic Trouble Codes which may be present. Refer to Powertrain On Board Diagnostic (OBD) System Check in Engine Controls -- 2.2L or Powertrain On Board Diagnostic (OBD) System Check in Engine Controls -- 4.3L.
2. Place the Ignition Switch in the Lock position.
3. Remove the battery. Refer to the Removal Procedure in Battery Replacement .
4. Observe that the battery hydrometer displays a green dot.
5. Install Battery Terminal Adapters.
6. Tighten to 15 N·m (11 Lb Ft).
7. Connect a voltmeter between the battery's positive and negative terminals.
8. Estimate the battery's temperature.
