TURN THE IGNITION OFF BEFORE CONNECTING OR DISCONNECTING THE TOOL FROM THE BATTERY to prevent damage to the tester or the vehicle's electronic components. DON'T SMOKE OR HAVE ANY FLAMES NEAR THE VEHICLE when testing. Fuel and battery vapors are highly flammable. DO NOT WEAR LOOSE CLOTHING OR JEWELRY WHEN WORKING ON AN ENGINE.
ABOUT THE BT100W The BT100W is a battery tester that applies the most advanced conductance testing technology and incorporates reverse polarity protection. It is designed to help technicians locate faults quickly by taking accurate measurements of the vehicle battery's actual Cold Cranking Amps (CCA) and State of Health (SOH), as well as testing the cranking system and charging system.

SECTION 3 GETTING STARTED 3.1 What Are the Most Commonly Used Car Batteries? Cars are powered by lead-acid batteries. The most commonly used ones are listed below: ● Flooded Lead Acid Batteries (Wet): This is the oldest/most common car battery type, also known as a "SLI battery." The Flooded Battery is usually made of 6 cells with a liquid electrolyte solution of sulfuric acid and water that needs to be topped off periodically.
