1. SAFETY
1.1. PERSONAL PRECAUTIONS
9Ensure that there is another person within hearing range and close enough to come to your aid, should a problem arise when working
near a lead-acid battery.
9Wear safety eye protection and protective clothing. Avoid touching eyes while working near battery.
9Have fresh water nearby in case battery acid contacts skin, clothing, or eyes.
9Rinse immediately with water if battery acid contacts skin or clothing. If acid enters eye, flush eye immediately with cool, clean
running water for at least 15 minutes and seek immediate medical attention.
9Remove personal metallic items such as rings, bracelets, necklaces and watches. A lead-acid battery can produce a short-circuit current
which is high enough to weld such items to the vehicle and cause severe burns.
9Ensure that hands, clothing (especially belts) are clear of fan blades and other moving or hot parts of engine. Remove ties and contain
long hair.
8DO NOT smoke or allow a spark or flame in the vicinity of the battery or engine.

4. TEST PREPARATION
4.1. Be sure area around battery is well ventilated while battery is being tested.
4.2. Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
4.3. Inspect the battery for cracked or broken case or cover. If battery is damaged, DO NOT use tester.
4.4. If the battery is not sealed maintenance free, add distilled water in each cell until battery acid reaches level specied by the
manufacturer. This helps purge excessive gas from cells. DO NOT overll.
4.5. If necessary to remove battery from vehicle to test, always remove earth terminal from battery rst. Make sure all accessories in the
vehicle are o󰀨 to ensure you do not cause any arcing.
5. OPERATION
NOTE: Each time you connect the tester to a battery, the tester will run a quick cable verication to ensure a proper connection
through the output cables to sensors in the clamp jaws. If the connection checks out OK, the tester will proceed to the Home Screen.
If the connection is poor, the display will show “CHECK CABLE”. In this case, check cable connections for visible signs of damage, as
you may need to re-connect the clamps to the battery or replace the cable end.
5.1. BEFORE TESTING:
5.1.1. Before you test a battery in a vehicle, turn o󰀨 the ignition, all accessories and loads. Close all the vehicle doors and the boot/tailgate.
5.1.2. Make sure the battery terminals are clean. Wire brush them if necessary.
5.1.3. Clamp the black load lead to the vehicle negative battery terminal. Clamp the red load lead to the vehicle positive battery terminal.

5.4.4. Press ENTER to begin charging system test.
5.4.5. Press the ENTER key, one of the three results will be displayed along with the actual reading measured.
HIGH CHARGING VOLTS WHEN TESTED AT IDLE
The voltage output from the alternator to the battery exceeds the normal limits of a functioning
regulator. Check to ensure there is no loose connection and the ground connection is normal.
If there is no connection issue, replace the regulator. Since most alternators have the regulator
built-in, this will require you to replace the alternator. The normal high limit of a typical automotive
regulator is 14.7 volts +/- 0.05. Check manufacturer's specifications for the correct limit, as it will
vary by vehicle type and manufacturer.
CHARGING SYSTEM NORMAL WHEN TEST AT IDLE
The system is showing normal output from the alternator. No problem is detected.
LOW CHARGING VOLTS WHEN TEST AT IDLE
The alternator is not providing sufficient current to the battery. Check the belts to ensure the
alternator is rotating with engine running. If the belts are slipping or broken, replace the belts and
retest. Check the connections from the alternator to the battery. If the connection is loose or
heavily corroded, clean or replace the cable and retest. If the belts and connections are in good
condition, replace the alternator.

functioning properly. If the mounting and belts are good, replace the alternator.
5.4.9. Press the ENTER key to continue to test the charging system with accessory loads. One of three
results will be displayed along with the actual testing measured.
CHARGING SYSTEM HIGH WHEN TESTED WITH ACCESSORY LOADS
The voltage output from the alternator to the battery exceeds the normal limits of a functioning
regulator. Check to ensure there are no loose connections and that the ground connection is
normal. If there are no connection issues, replace the regulator. Since most alternators have the
regulator built-in, this will require you to replace the alternator.
CHARGING SYSTEM LOW WHEN TESTED WITH ACCESSORY LOADS
The alternator is not providing sufficient current for the system’s electrical loads and the charging
current for the battery. Check the belts to ensure the alternator is rotating with the engine running.
If the belts are slipping or broken, replace the belts and retest.
Check the connections from the alternator to the battery. If the connection is loose or heavily
corroded, clean or replace the cable and retest. If the belts and connections are in good working
condition, replace the alternator.
CHARGING SYSTEM NORMAL WHEN TESTED WITH ACCESSORY LOADS
The system is showing normal output from the alternator. No problem detected.
5.4.10. Press ENTER when charging system test is completed. Turn all accessory loads and engine off.
Press ENTER to read the system test results.
IN VEHICLE TEST
This is a combination test of both battery test and system test. Please refer to above testing procedures or follow the instructions on the
display of the tester.
GLOSSARY
What is a GEL battery?
A gel battery is a lead-acid electric storage battery that:
■ is sealed using special pressure valves and should never be opened.
■ is completely maintenance-free.
■ uses thixotropic gelled electrolyte.
■ uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded lead-acid battery
(particularly in deep cycle applications).
■ is non-spillable, and therefore can be operated in virtually any position. However, upside-down installation is not recommended.
■ Connections must be re-torqued and the batteries should be cleaned periodically.

What is an AGM battery?
An AGM battery is a lead-acid electric storage battery that:
■ is sealed using special pressure valves and should never be opened.
■ is completely maintenance-free.*
■ has all of its electrolyte absorbed in separators consisting of a sponge-like mass of matted glass fibres.
■ uses a recombination reaction to prevent the escape of hydrogen and oxygen gases normally lost in a flooded lead-acid battery
(particularly in deep cycle applications).
■ is non-spillable, and therefore can be operated in virtually any position. However, upside-down installation is not recommended.
■ Connections must be retorqued and the batteries should be cleaned periodically.
What is a VRLA battery?
Valve Regulated Lead Acid Battery – This type of battery is sealed Maintenance Free with a “Bunce” Valve or Valves in the top of them
that opens when a preset pressure is realized inside the battery and let’s the excess gas pressure out. Then the valve resets itself.
What is a SLI battery?
These initials stand for Starting, Lighting and Ignition, which are the three basic functions which a battery has to perform on all
normal vehicles. Batteries given this description will have been specifically designed for service on cars and trucks within a
voltage controlled electrical system. Those SLI batteries which are intended for heavy haulage vehicles fitted with large diesel motors may
often be called COMMERCIAL batteries. They have to be much more powerful and more robust than batteries intended for cars.
What is STATE OF HEALTH?
It means how much battery capacity is left (%) comparing with the marked original battery capacity.
What is STATE OF CHARGE?
It means how many percent of the battery is actually charged.
What is CCA (COLD CRANKING AMPS)?
The current in amperes which a new fully charged battery can deliver for 30 seconds continuously without the terminal voltage falling
below 1.2volts per cell, after it has been cooled to 0OF and held at that temperature. This rating reflects the ability of the battery to deliver
engine starting currents under winter conditions.
What is AMPERE-HOUR?
The unit of measurement of electrical capacity. A current of one ampere for one hour implies the delivery or receipt of one ampere-hour.
