SECTION 4 BATTERY TEST
● CONNECT THE CLAMPS TO THE VEHICLE'S BATTERY
TERMINALS. RED CLAMP TO THE POSITIVE (+)
TERMINAL AND BLACK CLAMP TO THE NEGATIVE (–).
● ALWAYS DISCONNECT THE NEGATIVE CABLE FROM
THE BATTERY FIRST AND RECONNECT IT LAST.
● The AL500B only supports Lead-Acid Batteries.
LITHIUM-ION BATTERIES ARE NOT SUPPORTED!
● ALWAYS WEAR EYE PROTECTION EQUIPMENT
avoiding direct skin or eye contact with corrosive
liquids.
● PLEASE CONNECT THE VEHICLE TO AN EXTERNAL
POWER SOURCE. This will prevent the vehicle's
electronic control system from malfunctioning
due to a prolonged power disconnection when
conducting the out-of-vehicle test.
● For extra-safety, always have a FIRE EXTINGUISHER
by your side when working on a battery.
● FOLLOW ALL STANDARD SAFETY PRECAUTIONS
WHEN WORKING ON A BATTERY.
