GMC Sierra Batteries Parts Questions & Experts Answers
Q: How to accurately test batteries on GMC Sierra?
A: To accurately test a battery, it must be at or near a fully charged state. Begin by disconnecting the negative Battery Cable and visually inspecting the indicator eye or electrolyte level. Test the specific gravity of the electrolyte using a hydrometer and charge the battery if necessary. Perform an open circuit voltage test using a digital voltmeter and charge the battery if the voltage is less than 12.5 volts. Use a battery load-testing tool to evaluate the battery's ability to operate the Starter and other accessories during periods of heavy amperage draw. Conduct a battery drain test to determine if there is a constant drain on the vehicle's electrical system. To remove the battery, disconnect the cables and remove the front fender rear upper brace, battery tray support bracket, hold-down clamp bolt and clamp. Clean and inspect the battery tray before installation.
