1. BATTERY TEST
1.1 Connect the tester clamps to the
battery posts, red to the positive (+)
terminal and black to the negative (-)
terminal. Rock each clamp back and
forth for better contact.
1.2 Once the display lighted up, it will
prompt you with instructions to
proceed with the test. Follow the
instructions and if it ask you to select
the rating system: CCA, DIN, EN,
JIS#, IEC; select the one according
to the battery rating. If you cannot
find its rating then select Unknown.
1.3 It will run through a self-test and
when completed it displays the Main
Menu as shown below:
New: Clear Memory
•Clear the last tested results stored
in its memory
Continue Test…
•Continue the last test on the same
car from where you had stopped.
Last Test Result
•Review the test results of the last
tested car.
1.4 After you have made your choice,
selecting “New: Clear Memory” or
“Continue Test…” press ENTER will
proceed to the display below:
1.5 Pressing ENTER will proceed to

If the battery is rated in JIS#, EN, DIN
and EIC refer to the conversion list
provided to convert to CCA rating before
keying into the Analyser. If either is not
available on the battery label, select
Unknown.
1.6 Once you had the system rating in
mind, press ENTER key and the
display will show:
Key in the battery rating values using
the LEFT or RIGHT arrow key for
increase or decreases the values by
step of 100 units. For double digits
increase or decrease, use the UP or
DOWN key by step of 5 units each
press.
1.7 Once the CCA rating of the battery is
confirmed, press ENTER key will
start the testing process and will
display the result in less than 5 sec.
RESULTS: Good
•‘Good’ indicates the battery in good
condition. ‘Replace’ indicates that
the battery needs to be replaced.
Voltage: 12.46V
•This indicates the tested battery
voltage (12.46V). It depends on the
stage of charge on the battery:
CCA (Cold Cranking Amps): 406 CCA
•CCA rating is being used here. If
other rating (DIN or JIS# or EN or
IEC) then it will base on the
selected respective rating to
calculate the results.
Int. R (Internal Resistance): 6.72mΩ
•Internal resistance should fall
between 2.0mΩ ~ 15.0mΩ for
normal condition.
LIFE: 50%
•Indicates the battery life expectancy in
percentage. If the reading is greater
than 45%, RESULT will display Good.
It the reading is less than 45%,
RESULT display Replace.

2. GROUNDING TEST
2.1 Make sure that the engine is
switched OFF. Attach the Analyser
clips onto the battery terminal posts
[Red to (+) and Black to (-)] the unit
will power up and momentarily
display LCD screen as shown below.
2.2 It will run through a self-test and
when completed it displays the Main
Menu as shown below:
2.3 Pressing DOWN key once will scroll
down to the “Grounding Test”
2.4 Pressing ENTER key will proceed to
the display as follows.
2.5 Press ENTER key again, it will start
analysing.
2.6 Once it has finished analysing, it will
prompt you with an instruction stating
that you should unclamp the black
battery clip from the battery negative
terminal and clamp it to the engine
body within 15 seconds time limit.
NOTE: 15 seconds is given to establish
the contact to the engine body failing
which the data obtained earlier will be
lost. Then you need to repeat the whole
testing procedures again.
2.7 Once the Black clip is clamped onto
the engine body it will start analysing.

6. LIMITED WARRANTY
This Battery Electrical System Analyser BESA11
is warranted to be free from defects in material
and workmanship for a period of 12 months from
the date of purchase and is subjected to the
following terms and conditions:
6.1 Within the warranty period, the
manufacturer will repair or replace, at
their options, any defective parts and
return to the owner in good working
order.
6.2 Any repaired or replaced parts will be
warranted for the balance of the
original warranty or 90 days from the
date of repair, whichever is longer.
6.3 Cost of delivery charges incurred for
the repair of the product (to and from
the manufacturer) will be borne by
the owner.
6.4 The warranty covers only the defects
arises as a result of normal use and
does not cover those arise from:
•Unauthorized modification and
repair
•Improper operation or misuse
•Accident or neglect such as
dropping onto hard surfaces.
•Contact with water, rain or extreme
humidity or heat.
•Physical damages such as cables
broken, surface cracks, etc.
Caution: Never lay tools on the
battery top. You may short the
terminals together causing harm
to yourself, the tools or the
battery. Always follow Battery
Council International safety
recommendations.
Warning:
Battery terminals
contain lead compounds which
is hazardous to our body if
consumed. Please wash your
hand immediately after
handling.
Performing Battery Test while it is still in the
car:
Vehicle that was running has to have its engine
OFF first and then switch ON the headlights for
30 seconds to remove the surface charge. After
the headlights had switched OFF, let the battery
rest for at least 1 minute to recover before
testing commences.
The car engine and all other accessory loads
must be OFF during test in order to have an
accurate result. When attaching the analyser
clips, make sure that the battery posts were not
oxidized or badly corroded. Clean them first
before clamping to it. Do not clamp onto the
steel bolts directly which may give inaccurate
and inconsistent results.
Testing on stand-alone batteries:
Clean the battery posts with a wire brush prior
testing. For side- post batteries, install stud
adaptors. Do not use steel bolts for better
results.
