1.0 - Introduction
1.1- BESA 12 (Battery Electrical System Analyser):
This Analyser uses the modern technology in battery testing which can test
batteries as they are without charging before test. Testing procedures are quick
and easy with repeatable results. Test Results can be printed directly on attached
mobile printer or it can be stored in the computer for records.
1. Battery Test:
Analyses the battery condition using microprocessor controlled testing
methods without the need of fully charging it before test.
The unit consumes very little current during testing hence the test can
be repeated numerous times without worry of draining the battery and
its results are highly accurate.
Extremely safe as it does not create any sparks during clamp on and it
takes less than 7 seconds to obtain the full analysed results of tested
battery.
2. Grounding Test:
Analyses the condition of the electrical return circuit contacts resistance
which were connected to the engine or chassis body from the battery
terminal with results and recommendations display after test.
3. Starter Test:
Checks the cranking effectiveness of the battery to predict when the
battery will fail to crank a vehicle basing on voltage profiles with results
and recommendations display.
4. Alternator Test:
This test checks the alternator charging condition during load at 2,000
RPM and without load at 3,000 RPM with results and recommendations
display after each test.
This Analyser is maintenance free and does not require internal batteries. It
powers up when connected to the battery posts during testing or through an
external 12 Volts DC source for later review of the test results.

2.0 Safety Measures:
For safety reasons, read this manual thoroughly before operating the Tool.
Always refer to and follow the safety instructions and testing procedures
provided by the car or equipment manufacturer. The safety messages presented
below and throughout this user’s manual are reminders to the operator to exercise
extreme care when using this test instrument.
2.1 Safety Precautions:
When the engine is running, it produces carbon monoxide, a
toxic and poisonous gas. Always operate the vehicle in a well
ventilated area. Do not breathe exhaust gases – they are
hazardous that can lead to death.
To protect your eyes from propellant object such as caustic
liquids, always wear safety eye protection.
Fuel and battery vapors are highly flammable.
DO NOT SMOKE NEAR THE VEHICLE DURING TESTING.
When engine is running, many parts (such as pulleys,
coolant fan, belts, etc) turn at high speed. To avoid serious
injury, always be alert and keep a safe distance from these
parts.
Before starting the engine for testing or trouble shooting,
always make sure the parking brakes is firmly engaged. Put
the transmission in Park (automatic transmission) and
Neutral (manual transmission).
Always block the drive wheels.
Never leave vehicle unattended while testing.

AE TOOL LTD
l
USER MANUAL VERSION 1301
l
www.aetool.com
Never lay tools on vehicle battery. You may short the
terminals together causing harm to yourself, the tools or the
battery.
Engine parts become very hot when engine is running. To
prevent severe burns, avoid contact with hot engine parts.
Do not wear loose clothing or jewelry while working on
engine. Loose clothing can get caught in fan, pulleys, belts,
etc. Jewelry can conduct current and can cause severe
burns if comes in contact between power source and
ground.
When the engine is running, be cautious when working
around the ignition coil, distributor cap, ignition wires and
spark plugs. They are HIGH VOLTAGE components that can
cause electrical Shock.
Always keep a fire extinguisher readily available and easily
accessible in the workshop.
2.2 Other Precautions:
•This Battery Analyser is meant for testing of 12 Volts batteries only.
•Its operating voltage is from 9V ~ 15V DC and should not be tested on 24V
directly. It will cause damage the unit. For 12V x 2 batteries (in series or
parallel), disconnect the connections and test them individually.
•Battery that has just been charged by the charger contains surface charge
and it should be discharged by turning ON the Head lights for 3~5 minutes
before testing.
•Always attached the analyser clips on the lead side of the battery terminal
posts during testing so that it has a good contact. This will provide better
and accurate results.
•Do not attach the analyser clips directly onto the steel bolt that tightened to
the battery terminal posts; this may give inaccurate readings or

AE TOOL LTD
l
USER MANUAL VERSION 1301
l
www.aetool.com
inconsistent results. (Note: This also applies to all other battery testing
methods.)
•If the battery terminal posts were oxidised or badly corroded and the
connections were bad, the analyser will prompt you to check the
connections. In this case, clean the terminal posts and performs testing
directly on the terminal posts it-self.
•During testing on the battery whist it is still in the car, make sure the
engine is OFF.
•Do not store the analyser near high humidity or temperature area.
Exposing to extreme temperatures will cause damage to the unit.
3.0 Working with Batteries
Lead-acid batteries contain a sulfuric acid electrolyte, which is a highly corrosive
poison and will produce gasses when recharged and explode if ignited. It can hurt
you badly.
When working with batteries, make sure you have plenty of ventilation, remove
your hand jewelry, watch and wear protective eyewear (safety glasses), clothing,
and exercise caution.
Do not allow battery electrolyte to mix with salt water. Even small quantities of this
combination will produce chlorine gas that can KILL you!
Whenever possible, please follow the manufacturer's instructions for testing,
jumping, installing, charging and equalising batteries.
Never disconnect a battery cable from a vehicle with the engine
running because the battery acts like a filter for the electrical
system.

AE TOOL LTD
l
USER MANUAL VERSION 1301

www.aetool.com
Unfiltered [pulsating DC] electricity can damage expensive
electronic components, e.g., emissions computer, radio, charging
system, etc.
Turn off all electrical switches and components; turn off the ignition
before disconnecting the battery.
For non-sealed batteries, check the electrolyte level. Make sure it is
covering the plates, and it is not frozen before starting to recharge
(especially during winters).
Do not add distilled water if the electrolyte is covering the top of the
plates because during the recharging process, it will get warm and
expand. After recharging has been completed, recheck the level.
Reinstall the vent caps BEFORE recharging, recharge ONLY in well-
ventilated areas, and wear protective goggle.
Do NOT smoke or cause sparks or flames while the battery is being
recharged because batteries give off explosive gasses.
If your battery is an AGM or a sealed flooded type, do NOT recharge
with current ABOVE 12% of the battery's RC rating (or 20% of the
ampere-hour rating).
Gel cells should be charged over a 20-hour period and never over
the manufacturer's recommended level or over 14.1 Volts DC.
Follow the battery and charger manufacturer's procedures for
connecting and disconnecting cables and other steps to minimize
the possibility of an explosion or incorrectly charging the battery.
You should turn the charger OFF before connecting or
disconnecting cables to a battery.
Do not wiggle the cable clamps while the battery is recharging,
because a spark might occur, and this could cause an explosion.
Good ventilation or a fan is recommended to disperse the gasses
created by the recharging process.
If a battery becomes hot, over 43.3 °C (110 °F), o r violent gassing or
spewing of electrolyte occurs, turn the charger off temporarily or
reduce the charging rate.
When charging the battery in the car with an external MANUAL
charger, make sure that it will not damage the vehicle's electrical
system or components with high voltages.
Even if this is a remote possibility, it is best to disconnect the
vehicle's battery cables from the battery BEFORE connecting the
charger.
