BT101 BATTERY TESTER
BT201 BATTERY/CHARGING/STARTING
SYSTEM ANALYZER
TEST PROCEDURES / OPERATING INSTRUCTIONS
IMPORTANT:
1. For testing 12 volts batteries (BT101/BT201), and
for testing 12 volts charging/Starting system (BT201).
The capacity range:
SAE : 200~1200 CCA
DIN : 110~670 CCA
IEC : 130~790 CCA
EN : 185~1125 CCA
CA(MCA) : 240~1440 CA(MCA)
2. Suggested operation range 32℉(0℃) to 122℉(50℃) in ambient
temperature.
WARNING:
1. Working in the vicinity of a lead acid battery is dangerous.
Batteries generate explosive gases during normal battery operation.
For this reason, it is of utmost importance, if you have any doubt,
that each time before using your tester, you read these instructions
very carefully.
2. To reduce risk of battery explosion, follow these instructions and
those published by the battery manufacturer and manufacturer of
any equipment you intend to use in the vicinity of the battery.
Observe cautionary markings on these items.
3. Do not expose the tester to rain or snow.

- GB.2-V1 -
PERSONAL SAFETY PRECAUTUONS:
1. Someone should be within range of your voice or close enough to
come to your aid when you work near a lead acid battery.
2. Have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing or eyes.
3. Wear safety glasses and protective clothing.
4. If battery acid contacts skin or clothing, wash immediately with
soap and water. If acid enters eye, immediately flood eye with
running cold water for at least ten minutes and get medical
attention immediately.
5. NEVER smoke or allow a spark or flame in vicinity of battery or
engine.
6. Be extra cautious to reduce risk of dropping a metal tool onto the
battery. It could spark or short-circuit the battery or other electrical
parts and could cause an explosion.
7. Remove personal metal items such as rings, bracelets, necklaces
and watches when working with a lead acid battery. It can produce
a short circuit current high enough to weld a ring or the like to
metal causing a severe burn.
PREPARING TO TEST:
1. Be sure area around battery is well ventilated while battery is being
tested.
2. Clean battery terminals. Be careful to keep corrosion from coming
in contact with eyes.
3. Inspect the battery for cracked or broken case or cover. If the
battery is damaged, do not use tester.
4. If the battery is not sealed maintenance free, add distilled water in
each cell until battery acid reaches level specified by the
manufacturer. This helps purge excessive gas from cells. Do not
overfill.
5. If necessary to remove battery from vehicle to test, always remove
ground terminal from battery first. Make sure all accessories in the
vehicle are off to ensure you do not cause any arcing.

OPERATION & USE:
BATTERY TEST - BT101/BT201 (Test for 12V batteries)
1. Before you test a battery in a vehicle, turn off the ignition, all
accessories and loads. Close all the vehicle doors and the trunk lid.

necessary. Clamp the black load lead to the vehicle negative battery
terminal. Clamp the red load lead to the vehicle positive battery
terminal.
3. Make sure you have put 9V battery into the battery chamber. If the
9V battery runs out of power, screen will show ibtL (INTERNAL
BATTERY LOW). Replace 9V battery before starting the test.
Note: Nothing will show on the display until the tester is
connected to a vehicle battery.
4. LED display will light on and show the voltage of the battery
XX.XX on the screen. Press "ENTER" to the next step.
NOTE: If you see HI / ---- / Blank appeared on the screen or
screen flickers, please refer to TROUBLESHOOITING.

TROUBLESHOOTING
–If the screen shows HI :
Voltage of the tested battery is over 15.00V & too high for 12V
battery. BT101/BT201 won't work under this situation. Please
re-check if the tested battery is 12 volts.
–Voltage of the tested battery is under 1.5 Volts. BT101/BT201 won't
work under this situation. Please recharge the battery & retest. If
reading is the same, the battery should be replaced immediately.
–If the screen shows blank :
The voltage of the tested battery is too low to serve the BT101/
BT201. Please recharge the battery retest. If reading is the same, the
battery should be replaced immediately. Or the clamps are connected
reversely. Please check & re-connect it.
–The screen shows ---- :
The voltage is unstable. For a just completely the charged battery or
other factors cause the battery’s voltage unstable, the LED display
shows ----. Please wait 15~30 minutes to let the battery voltage
stable and test the battery or eliminate the factors to test the battery.
