SPECIFICATION

ENGLISH

For your safety and the safety of others, as well as to

avoid any damage to the product and your vehicle,

carefully read and make sure you fully understand

this manual's safety instructions in its entirety. You

must read the vehicle's service manual, the battery

stated precautions or instructions before and during

any test or service procedure.

ONLY OPERATE TESTS IN A WELL-VENTILATED AREA

since the vehicle produces carbon monoxide (a

toxic, poisonous gas, and particulate matter) when

the engine is running.

ALWAYS BE AWARE OF MOVING PARTS (such as

coolant fans, pulleys, belts) since they spin or turn at

high speeds when the engine is running.

DO NOT TOUCH HOT ENGINE PARTS to prevent

severe burns. The motor parts can get extremely hot

when the engine is running.

TURN THE IGNITION OFF BEFORE CONNECTING OR

DISCONNECTING THE TOOL FROM THE BATTERY

to prevent damage to the tester or the vehicle's

electronic components.

DON'T SMOKE NEAR THE VEHICLE when testing.

FIRST PRIORITY!

READ THE INSTRUCTIONS BEFORE USING

EN I 5

DO NOT WEAR LOOSE CLOTHING OR JEWELRY

WHEN WORKING ON AN ENGINE. Loose clothing can

easily be caught in the engine's fan, pulleys, belts,

etc., and jewelry is highly conductive, which may

cause severe burn or electric shock if it contacts

electricity.

DO NOT CUT THE PRODUCTS CORDS OR SUBMERGE

THEM IN WATER. The product is an electrical device

that can cause shock and severe burns.

WARNING: Battery acid is extremely corrosive. If acid

gets into your eyes, RINSE THEM THOROUGHLY WITH

COLD RUNNING WATER FOR AT LEAST 20 MINUTES

AND SEEK MEDICAL ATTENTION IMMEDIATELY.

If battery acid contacts your skin or clothing, WASH

IT IMMEDIATELY WITH A SOLUTION OF WATER AND

BAKING SODA.

Where is the battery of a car located?

Let's take the following picture as a reference:

Explanation of LCD Display:

Bluetooth icon. A ashing icon indicates the tester is

not connected to the App; a solid icon indicates the

tester is connected.

This symbol indicates NOT to test twice within 10

seconds.

This symbol indicates voltage is too low. Charge the

battery rst.

This symbol indicates an over temperature. Wait until

the temperature is normal, and then test again.

This symbol indicates a poor connection between the

battery and clamps. Please reconnect.

This symbol indicates the tester reset failed. Please

reconnect the battery and clamps.

This symbol indicates the tester is abnormal or the

battery capacity is beyond the test range. Please

reconnect the battery and clamps, and try again.

1) Most models hold the battery in the engine bay, under the

hood, in one of the front corners. See battery location ① and ②

in Figure 3.1.1.

2) To balance uneven weight distribution, some manufacturers

hold the engine in the trunk. See battery location ⑤, ⑥, and

⑦ in Figure 3.1.1. In this case, the battery may have a plastic

cover that should be removed prior to any testing.

3) For some models, the battery might be stored underneath the

rear seat. See battery location ④ in Figure 3.1.1.

4) For other vehicles, the battery can be located underneath the

passenger seat. See battery location ③ in Figure 3.1.1.

WARNING:

DO NOT TEST THROUGH THE JUMPSTART POSTS. For

models that hold the battery under the seat or in the trunk,

the manufacturer usually includes jumpstart connector

conductor posts under the hood (see Figure 3.1.2) to make

jumpstarting easier. However, to ensure data accuracy and

operation safety, DO NOT CONNECT THE BATTERY TESTER

TO THE JUMPSTART POSTS.

1) Battery Capacity: 80Ah

Battery Capacity is dened as the total amount of electricity

generated in the battery in a certain time, and is measured in

ampere hours (Ah).

2) Voltage: 12V

When fully charged, automotive batteries should measure

at 12.6 volts. However, this measurement should be from 13.7

to 14.7 volts when the engine is running. If the battery tester

1) Before connecting the clamps to the terminals, please use

sandpaper to polish off the corrosion on the battery terminals.

With this, you can avoid inaccurate test values.

2) Attach the red clamp to the positive (+) terminal, and connect

the black clamp to the negative (-).

• ALWAYS KEEP THE RED & BLACK CLAMPS FROM

TOUCHING.

• ALWAYS DISCONNECT THE NEGATIVE CABLE FROM THE

BATTERY FIRST AND RECONNECT IT LAST.

3) Once the clamps are properly connected, the battery tester

will power on automatically and be ready to conduct tests.

Connect the Clamps to the Battery Terminals (See

Figure 3.3.1)

reads less than this standard, it means that the battery's

resting voltage is weak. In this case, typically, the battery needs

to be charged or replaced.

3) CCA: 650A (SAE)

The CCA rating refers to how many amps a 12-volt battery

can deliver at 0°F in 30 seconds while maintaining at least a

7.2V voltage. This means that the higher the CCA rating is, the

easier the engine can be cranked in cold temperatures.

SECTION 4 TEST THROUGH

THE TEST BUTTON

Soon after the battery tester is powered on, the real-time voltage

of the battery will be displayed on the screen, and the Bluetooth

icon will ash.

Press the Test Button, and wait for several seconds. The

corresponding Battery Voltage Indicator (FULL / MEDIUM / LOW)

and Battery Health Indicator (GOOD / MEDIUM / BAD) will light

up to show the test result.

the diode rectier to turn into a direct current - that's when

the ripple occurs
