Battery Electrical System Analyser
(12-1015)
For testing all 12V automotive starting batteries
rated in CCA, SAE, DIN, JIS#, IEC, EN and CA.
Also for testing vehicle Electric
al System.
Quick Start Guide
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.

LIMITED WARRANTY
This Battery Electrical System Analyser [12-1015] 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:
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.
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.
3. Cost of delivery charges incurred for the repair of
the product (to and from the manufacturer) will be
borne by the owner.
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
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.
• 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.

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.

Rating: 630 CCA
Volts: 12.45 V
Int. R: 6.72 mOhm
Life: 76%
RESULTS: Good
‘Good’ indicates the battery in good
condition. ‘Replace’ indicates that the battery
needs to be replaced.
Voltage: 12.45V
This indicates the tested battery voltage
(12.45V). 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
(SAE or DIN or JIS# or IEC or EN or CA)
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: 76%
Indicates the battery life expectancy in
percentage.
If the reading is greater than 45%,
RESULT will display Good. Anything less
than 45%, RESULT display Replace.

Important:
The tester has to be connected to a 12V battery
in order to work with the mobile printer. This is
because it needs higher Amps to operate which
the PC USB output is unable to provide.
To print 1 test at a time, just press key on,
while the test results are still on the screen. The

PRINTER SETUP
SELECT DISPLAY LANGUAGE
1. The printer will only work when connected
directly to a 12Volt car battery because it
needs higher amps than an USB port from
the PC can provide. The red LED indicates
the printer is ON and the green LED will blink
when the printer has run out of paper. If
there is paper present and it still blinks then
the printer has overheating problem. The
green LED will also stay lighted up when
there is no paper if BST 12 is connected to
the PC through the USB port.
2. Open the printer cover (Fig. 5a). Place the
thermo paper roll into the slot with the paper
edge facing up (Fig. 5b). Make sure the
paper is about ¾ in out when the printer
cover is closed (Figure 5c).
