Introduction
12-2415 is our latest version of Battery Analyser which test 12V systems (4 functions) and 24V systems on
Starters and Alternators (Normal and Smart). This tester revolutionized its display format and is the first in the
world with fully graphical display. The graphical display is simple; with step by step instructions enable the user to
clearly understand the operation. The symbols used are universal which solve language barrier.
The unit comes with an integrated printer so the graphical results can be printed immediately after each test. Its
memory stores up to 70 previous test results for later viewing. With its PC Link feature, allows the results to be
transferred and stored in the computer via an USB cable and PC Link software installed into the computer
beforehand.
The Battery Analyser operates on all 12V or 24V Batteries and is able to perform four tests namely:
1. Battery Test:
This Test is intended only on 12V batteries. The analyser clips (red & black) have to be clamped onto the
battery terminals. When the analyser detects the voltage present, the analyser will automatically remind the user
that it can test only on 12V battery when connected to the 24V system.
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 any worry of draining the battery and its results are highly accurate.
Extremely safe as it does not create any sparks during clamping and it takes less than 8 seconds to
obtain the full analysed results of tested battery.
Temperature compensated end Results.
It is powered up from the testing 12V or 24V battery. No maintenance is required during its lifetime
service.

2. Grounding Test:
Same as battery test, this test is also meant for 12V batteries only.
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:
This Test can be performed on 12V and 24V Starters.
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 Tests (with diode ripple test):
This test can be done on 12V and 24V Alternators (Normal or Smart).
These tests check the alternator charging conditions during load at 1,500 ~ 2,000 RPM, without load
at 2,500 ~ 3,000 RPM and the diodes ripple volts with results and recommendations display after
each test. This test will determine whether the alternator is performing its job properly.

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.
•Never lay tools on vehicle battery. You may short the terminals together causing harm to yourself, the
tools or the battery.
•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.
•Always keep a fire extinguisher readily available and easily accessible in the workshop.
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 people 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
equalizing batteries.
•Never disconnect a battery cable from a vehicle with the engine running because the battery acts like a
filter for the electrical system.

Version GS 17628
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.
•Do NOT smoke or cause sparks or flames while the battery is being recharged because batteries give off
explosive gasses.
Preparing for Test:
1. The Battery Analyser operating voltage is from 9V to 36V DC. For Battery and Grounding tests on 24V
system (12V x 2 batteries connected in series), disconnect the connection between each battery and
clamp the analyser clips to one battery at a time and test them individually. For Starter Test (Cranking)
and Alternator Test (Charging), these tests can be done on 12V or 24V system.
2. 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.
3. Always attached the tester 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.
4. Do not attach the tester clips directly onto the steel bolt that tightened to the battery terminal posts; this
may give inaccurate readings or inconsistent results. (Note: This also applies to all other battery testing
methods.)
5. During testing on the battery whist it is still in the car, make sure the engine, all accessories and load are
OFF. Close the trunk lid and all doors.
6. Inspect the battery for cracks or broken casing. Do not use the Tester if the battery is damaged.
7. If the battery is a WET type: non sealed maintenance free, top up the level as specified by the markings
on the battery with distilled water. This will help to purge the gas from the cells. DO NOT OVERFILL.
8. If necessary to remove the battery from the vehicle to test, ALWAYS remove the negative terminal from
the battery first. Make sure all accessories are OFF so that you do not cause any arcing.
Initial Setup
Printer paper installation:
Open the printer cover by pushing it upwards from the middle. Place the roll of thermal paper into the slot with the
paper edge facing up (Fig. 1). Make sure the paper is about 1.0 inch (25.4 mm) out when the printer cover is
closed (Fig. 2).

Note:
The information that has been keyed in will be shown in the result printout after test (see Fig.87).
Switch ON / OFF Key Sound beep
Whenever a key is press, there is a corresponding beep sound which can be heard as to indicate that a key has
been pressed. This sound can be switched ON or OFF by doing the following:
1. Go to the Main Menu as shown in Fig.4 above.
2. Press and hold key for about 3 seconds and a long beep sound will be heard which indicates
that the change has taken place.
3. Then press any key and the sound is OFF.
4. To reverse back, do the same procedure as mentioned in step 2 and the sound will be switched On.
Car / Truck Battery Test:
This test is intended for 12V Batteries but not on 24V.The reason is most trucks that use 24V systems have two
12V batteries connected in series to produce 24V. To test on 24V system (12V Battery x 2), disconnects the
connection between each battery and test one battery at a time.
The test results of individual battery is more accurate than testing two batteries at once due to the unwanted
resistance created by the cable joining of the first battery to the second battery that make 24V. So the battery test
is catered for all 12V Batteries only.
Performing Battery Test whilst it is still in the car or truck:
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 or truck engine and all other accessory loads must be OFF during test in order to have accurate
results. 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.
If the red and black clips were accidentally clamped directly on to the 24V output terminals of the battery while
testing truck batteries, the Analyser display will show (Fig.7 and Fig.8) as below:

test them individually (one at a time) Fig. 9 below.
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.
1. Clamp the Analyser black clip to the battery negative terminal (-) and red clip to the battery positive
terminal (+). The Analyser LCD will light up with the wakeup screen (Fig.10).
2. When one of the Analyser clamps is not properly secured to the battery posts, it will prompt you as shown
below (Fig. 11 and 12 flashing alternately). In this case, unclamp and clamp the Analyser clips again on
the battery posts. Here the Analyser will ensure that its contacts are good before conducting a test.
3. If the contacts between the battery and the Analyser have no problem, then the Menu screen will display
as shown below (Fig.13):

Please take Note:
This output value (120 CCA) is related to the actual power available in the battery in relation to
that battery's rating (180 CCA). On average, a new battery's CCA as measured by this tester will
read 10-15 % higher than its stated rating.
As the battery ages, the CCA number measured by this tester will decrease so it reads near its
rating. While this value is not the same as a CCA test, it is the best available measurement for
showing a battery's current condition in relation to its rating.
From the above example, a 180 CCA rated battery measuring 120 CCA available power does not
mean that the battery would pass a CCA test at 120 CCA.
The available power reading shows that the battery is not able to perform up to its rated ability
(180 CCA).
In comparison to another battery when fully charged, the 180 CCA battery measuring 120 CCA is
no stronger than a 100 CCA battery showing 100 CCA available power when fully charged.
The available power number is meant for comparison to its own rating. In fact, in this example the
180 CCA battery was failing to perform to its rating, while the 100 CCA battery is still working.
Basing on the Society of Automotive Engineers (SAE) in America, CCA test is a manufacturing
process control test applicable only on new, fully charged batteries. It does not produce an actual
value, but is a PASS / FAIL test.
It measures the discharge load, in amps, that a battery can supply for 30 seconds at 0°F/-18°C
while maintaining a voltage of 1.2 volts per cell (7.2 volts per battery) or higher.
Thus, the CCA test shows the minimum power requirement for the battery as rated, which means
a battery rated at 400 CCA must measure 7.2 volts or above for 30 seconds when a load of 400
amps is applied at 0°F/ -18°C.
5. Internal Resistance: 18.91mΩ
In normal condition, the internal resistance of the motorcycle battery should fall in the range of between 5.0
mΩ~ 45.0 mΩis considered to be good. Anything above 45.0 mΩresistance shows that its internal
plates has been aged or sulfated.
For car batteries, its internal resistance of 2.0 mΩ~ 15.0 mΩis considered to be good due to high CCA
value they have.
As a matter of fact, the higher the battery CCA readings obtained the lower the internal resistance should
be.

•SAE (The Society of Automotive Engineers) Standard.
SAE has established Cold Cranking Amperes (CCA) rating for batteries as their standard. Therefore this
rating is the same as CCA rating as mentioned above.
•IEC (International Electro technical Commission) Standard.
IEC amperes rating require that at 0
°
F (-18
°
C), the number of amperes that the 12V battery can deliver
while maintaining a voltage of at least of 8.4 Volts for 60 seconds during cranking.
•EN 1 (European Norms) Standard.
EN 1 amperes rating require that at 0
°
F (-18
°
C), the number of amperes that the 12V battery can deliver
while maintaining a voltage of at least 7.5 Volts for 10 seconds discharged at the rated current, followed
by 10 seconds rest, then it is discharged at 60% of the original current for further 73 seconds to give an
equivalent total discharge time at the lower current of 90 seconds still maintaining 7.5 Volts.
•EN 2 (European Norms) Standard.
EN 2 amperes rating require that at 0
°
F (-18
°
C), the number of amperes that the 12V battery can deliver
while maintaining a voltage of at least 7.5 Volts for 10 seconds discharged at the rated current, followed
by 10 seconds rest, then it is discharged at 60% of the original current for further 133 seconds to give an
equivalent total discharge time at the lower current of 150 seconds still maintaining 6.0 Volts.
•JIS# (Japanese Industrial Standard)
JIS # amperes’ rating is based on Ampere Hours and is calculated using 20 hours rating. In this manual, it
is using CCA ratings reference table list provided basing on the JIS model number.
•DIN (Deutsches Industrie Normen)Standard.
Basing on DIN , the rating requires that at 0
°
F (-18
°
C), the 12V battery is able to deliver the number of
amperes while maintaining a voltage of at least of 9.0 Volts for 30 seconds and 8.0 Volts for 150 seconds
during cranking.
•CA (Cranking Amperes) / MCA (Marine Cranking Amperes) Rating.
This rating is the number of amperes that a new fully charged battery can delivery at 32°F (0°C) for 30
seconds, while maintaining a voltage of at least 7.2 Volts for a 12V battery during cranking.
•?? (Unknown)
If you are not sure which ratings (CCA, EN, IEC, JIS or DIN) that the battery is based on, then choose this
setting. It will show the battery’s Voltage (State of Charge), CCA and the Internal Resistance (m
Ω
) only.
This selection can also be used to test 12V - Deep Cycle Batteries. An example of the results display is
shown below: (Fig.37)
To determine the condition of the tested Deep Cycle Batteries, refer the Volts reading – State of Charge
(should not fall below 12.60V when fully charged for Lead Acid Batteries, 12.85V for Gel Batteries and
12.80V for AGM Batteries) and the Internal Resistance [Int. R] of the tested battery should not be more
15 m
Ω
readings can be considered to be a good battery.

7. Batteries that had been left idle for long periods can still be tested with this analyser. To perform the
test, just clamp the analyser clips onto the battery terminals and it will display the screen (Fig.38) as
shown if its voltage falls below the normal 12.0 volts.
Note: Any battery whose voltage falls below 10.6V will be considered a shorted battery.
Press key to continue and the display will show: (Fig.39)
Check the battery ratings and enter it as described earlier and the results will show as an example below:
(Fig. 40 and Fig.41)
Fig.40 - Results shown [Recharge and test again], it indicated that the battery has to be fully charged first
before repeating the test. Reason: State of Charge: 11.09V is too low.
For Fig.41 - Results shown [To replace], this meant that the battery need to be replaced as its internal plate
resistance [Int. R] 19.21mΩis higher than 15 mΩlimit.
Pressing the key at any moment will exit and return back to the main menu display.
Starter Test:
This test is only available in test and it actually checks the cranking effectiveness of the 12V or
24V battery system during starting and also the starter condition.
1. With engine OFF, place the vehicle transmission in NEUTRAL for Manual and PARK for Automatic then
apply the hand brake.

2. Connect the tester to the battery terminals and the displays will light up as shown below.
From the main MENU (Fig.42), select by scrolling left using key
Press key to continue and the display will show:
Note: In event that you did not crank the engine while on this screen; the starter test will
be terminated after 30 seconds and return to the main menu.
3. Now switch the ignition key to ON and start cranking the engine until it starts. As soon as the engine
starts, the results will automatically display as shown in examples below :( Fig.44 or Fig. 45)
Note:
9.6 Volt is the voltage drop limit for 12V system whereas 19.2Volt is for 24V system. Voltage drop
more than the limits mentioned are considered bad.

Alternator Test:
This test is only available in Test. It checks the MAX and MIN charging voltages output of Normal
or Smart alternator at 2,500 ~3000 RPM without load and 1,500 ~ 2,000 RPM with all loads ON. As Normal and
Smart Alternators on a 12V and 24V systems have its own set of parameters, it can determine the alternator’s
charging conditions and with the test results you can check its condition when in reference with the vehicle’s
Service Manual.
No load testing at 2,500 ~ 3,000 RPM
1. With engine OFF, place the vehicle transmission in NEUTRAL for Manual and PARK for Automatic and
apply the parking brake.
2. Attach the Analyser clips onto the battery terminal posts and it will power up and lights up the LCD
display screens as shown below:
Note:
The Analyser will auto detect the battery voltage once it had clamped onto the battery
terminals, if it has detected a 24V battery then it will set its test perimeters to cater for 24V system
and vice versa if it is a 12V system.
