SPECIFIC SAFETY INSTRUCTIONS
1. When connecting the Battery Cables to the battery,
avoid creating sparks - especially when the battery is
being charged. Explosive gases are created.
2. DO NOT touch the cooling vents on the Load Tester
during or immediately after testing the battery; they
become very hot.
3. When placing the Load Tester in the vehicle’s engine
compartment, take special care that the metal housing
of the Tester does not come in contact with either
terminal of the battery or other electrical connections.
4. Be certain of the test battery polarity before connecting
the test Cable Clamps. The red Cable Clamp goes to
the positive terminal of the battery. The black Cable
Clamp goes to the negative terminal of the battery.
Reversing Load Tester Cable Clamps on the battery will
damage the tester.
5. DO NOT drop the Load Tester as it may affect proper
operation.
6. DO NOT smoke or have open flames near the battery.
7. DO NOT connect the Load Tester to the battery while
the engine is running. Turn the engine off before
connecting.
WARNING:This product contains chemicals known to
the State of California to cause cancer, birth defects or
other reproductive harm.
WARNING:Thoroughly read and understand the
provided product manual before attempting to use this
product.
WARNING:ALWAYS perform vehicle maintenance in a
well-ventilated area.
WARNING:DO NOT attempt to repair or disassemble
the tester. Contact customer service or a qualified service
professional.
WARNING:DO NOT attempt a test on a battery with a
broken case or cover.
WARNING:DO NOT smoke in the vicinity of a battery or
engine.
WARNING:DO NOT submerge the battery tester.
WARNING:DO NOT allow the battery tester to contact
any liquids.
WARNING:Remove all metal items from your body
(rings, bracelets, watches, etc.) to avoid risk of electric
shock and severe burns.
WARNING:During use, the metal casing will get hot
enough to burn skin or cause property damage. Always
carry the product by the handle. If the handle becomes
hot, allow the tester to cool prior to attempting use.
TESTING PREPARATION INSTRUCTIONS
1. Wipe the battery terminals with a cloth to remove any
dirt and grease.
2. Make sure the Load Knob (C) is in the OFF position.
Connect the red (positive) Cable Clamp (A) to the
positive terminal (+) on the 12V battery.
3. Connect the black (negative) Cable Clamp (B) to the
negative terminal (–) on the battery.
4. Turn the Load Knob (C) clockwise until the DC ammeter
reads 1/2 the Cold Cranking Amp (CCA) rating or three
times the amp hour (Ah) capacity of the battery. The
CCA and Ah rating are printed on the battery label.
Maintain load for 15 seconds to simulate an actual load
on the battery. After 15 seconds, the unit will make a
beep sound.
5. View the DC Volts Meter and read the battery condition.
Refer to the “Battery Condition Analysis” section on the
next page.
6. Turn the Load Knob (C) counterclockwise to OFF, and
remove the Cable Clamps from the battery.
NOTE:Freezing temperatures affect the battery test
reading. Decrease the battery rating 50 cold cranking
amps for each 50°F (10°C) below freezing 30°F (0°C).
TESTING SYSTEM INSTRUCTIONS
1. Turn the Load Knob (C) counterclockwise to the OFF
position.
2. Connect the Cable Clamps to the battery as previously
described.
3. Outside, start the vehicle engine and run at fast idle
speed.
4. View the DC Volt Meter and read the Alternator &
Regulator condition. Refer to the “Battery Condition
Analysis” section below.
5. Turn the vehicle’s engine off, then remove the Load
Tester Cable Clamps.
WARNING:Avoid Carbon Monoxide Poisoning. This
gas comes from the vehicle’s exhaust and is colorless
and odorless. It can cause SERIOUS INJURY and DEATH
if inhaled.

BATTERY CONDITION ANALYSIS
LOAD TEST / 15 Sec. (Display Reading)
Battery Condition
OK (Green area)
Battery Capacity is good. May or may not be fully charged.
Check the charge state by testing the Specific Gravity (SG)
with a Hydrometer. If SG is less than full charge, check for
possible charging system trouble. Recharge to full level.
BAD (Red area)
If the DC Volt Meter needle is failing, the battery is
defective or has a bad cell. For a quick check, turn the
Load Knob down (counterclockwise) and note DC Volts
Meter reaction. If voltage recovers to its full potential after
only a few seconds, the battery is probably defective. If the
voltage recovers slowly, the battery may only be run down.
Check specific gravity level, recharge, and retest.
CHARGING SYSTEM (Alt. & Reg. Test)
If the DC Volt Meter needle reads OK, charging system
is functional. If it falls on the low red or high red areas,
charging system may be malfunctioning.
STARTER MOTOR TEST
If starting your vehicle is difficult, you may have unnecessary
starter motor draw, which dramatically shortens battery life.
This test identifies starter motor performance.
1. Make sure your engine is running at normal operating
temperature, and that the battery is fully charged and in
good condition.
2. Connect the Red Clamp to the positive (+) terminal
post on the battery. Connect the Black Clamp to the
negative (-) terminal post on the battery.
3. Turn the Load Knob (C) counterclockwise to the OFF
position.
4. Disable the engine to make sure the car will not start.
Refer to your vehicle’s service manual.
5. While watching the DC Volt scale, crank the engine
briefly to determine the voltage reading during
cranking. A display reading of 9 volts or less indicates
excessive current draw. This may be caused by a bad
connection of a failing starter motor, or the battery
is too small for the vehicle’s requirements. Consult a
qualified mechanic.
6. When starter motor test is complete, remove Black (-)
Clamp from battery first; then remove Red (+) Clamp.
INSPECTION, MAINTENANCE, AND CLEANING
1. Periodically check all nuts, bolts, and screws for
tightness.
2. Store in a clean, dry location.
3. Clean the outside of the unit with a damp cloth.
Never use solvents to clean any parts of this tool. Use
compressed air to blow out debris from the load vents.
Allow tool to dry completely before use.
4. After each use, clean the cable clamps of any possible
battery electrolyte. Apply a thin coat of silicon grease to
prevent corrosion.
