Brief Introduction
The BT70 is a battery tester tool for testing the performance of start-up lead-acid
batteries. The device uses a large-screen LCD display, and the test process and
results can be displayed through sound alarms and icons. The internal protec-
tion of the device has been strengthened to prevent it from reverse polarity
connection, high voltage access and poor test clamp contact, which ensure
more security and convenience in the operation.
Safety rules and precautions
This manual includes instructions for using the instrument and warnings for safe
operation and how to maintain it. Please use the battery tester device strictly
according to the manual. This device strictly complies with GB4793. l Safety
requirements for electronic measuring instruments and IEC/EN61010-1 safety
standards for design and production.
● This product is suitable for the detection of 12V and 24V car batteries.
● The working voltage range is 8 volts to 30 volts with direct current (DC).
● When the battery is in just fully charged state, the voltage will be slightly
higher than the normal value. Please turn on the headlights for 2~3 minutes and
wait for the voltage to drop back to normal before testing.
● Before use, check whether the insulating layer of the test clamps is intact,
damaged, exposed, or disconnected. It is strictly prohibited to use the back
cover before it is closed, otherwise, there is a danger of electric shock.
● Do not use or store the device in harsh environments such as high tempera-
ture, high humidity, flammable, explosive, and strong electromagnetic fields.
● Do not change the internal wiring of the device at will to avoid damage to
the meter.
● If the car engine is running, do not put the equipment and accessories next
to the engine or exhaust pipe to avoid damage by high temperature.
Product icons and Description
Description of icons and test clamps:
● Voltage display:
1

● Battery status: high, medium, low ;
Determined Recommendation by status: good, charge or replace
Red test clamp: Positive wiring test clamp;
Black test clamp: Negative wiring test clamp.
Function instructions
The voltage detector has two modes: 12v/24v. After the device is powered on, it
will automatically identify the 12v or 24v battery voltage type and display the
measured voltage and battery status on the LCD screen.
Example display of 12V battery :

Example display of 24V battery :
Installation instruction
After confirming that the car battery is in normal condition, please install it in the
following order.
● Simply connect the red clamp to the positive of the battery, and the black
clamp to the negative of the battery, then the battery tester device is connected
with the car battery. Pay attention to ensure good contact, so as not to affect the
test results.
● After the connection is completed, the battery tester will automatically detect
and identify the 12v or 24v battery voltage type, and its voltage value and
battery status will be displayed on the LCD screen.
● The principle process of this product is:
After power on, the buzzer will beep once, and the 12v/24v battery will be
automatically detected and displayed. The indicator lamp lights up one after
another and the voltage is detected after three cycles of operation, and the
battery status is judged. After the test is completed, the buzzer beeps once, and
the LCD screen displays the voltage value and battery status.
※Precautions※
● If the voltage reading is greater than 15.0V (for a 24V system, the reading is
greater than 30.0V), please check if there is a problem with the voltage regula-
tor.
● If the voltage reading is less than 13.3V (for a 24V system, the reading is
less than 26.6V), please check the connection, wires, and generators.
● If the voltage reading is less than 12.8V (for a 24V system, the reading is
less than 25.6 V), please check whether the generator belt is worn out and the
3

wires are short-circuited.
※Precautions※
● The engine starting performance of the battery varies with factors such as
temperature, and the starting performance at low temperatures is poor.Therefore,
even if the battery decays to the same extent, it shows a poorer starting perfor-
mance at low temperatures than at room temperature.
● Since this product diagnoses the engine starting performance of the battery
based on the engine starting characteristics of the vehicle, this result may differ
from that of a battery tester.
● If an external power supply is used to start the engine through the booster
cable, the correct engine starting performance will not be displayed.(Usually, the
engine starting will show the correct engine cranking performance.)
● If the motor is turned without stepping on the clutch while the manual vehicle
is in gear, the correct engine starting performance will not be displayed.(Usually,
the engine starting will show the correct engine cranking performance.)
※Precautions※
● When the battery voltage is detected as low voltage, the buzzer will beep
five times, wait for three seconds and then cycle, then the “CHARGE” or
"REPLACE" icon will light up.
● When the battery voltage is detected as medium voltage or high voltage, the
“BATTERY GOOD” icon lights up.
Maintenance/inspection
⑴Clean car battery lifespan diagnose unit
● Wet the cloth with water, wring out, and wipe the dirt.
● Do not wipe with a dry cloth or other materials that may generate static
electricity.
● Do not use volatile oil (petroleum), thinner, gasoline and other organic
solvents as cleaning agents.
⑵ Installation inspection of connectors
● Make sure the test clamps are well-connected.
● If it is loose,the test clamp needs to be reconnected and fixed.
