For your safety, the safety of others, and 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 manufacturer's specic
safeguards, and observe the stated precautions or instructions
before and during any test or service procedure.
ALWAYS WEAR APPROVED EYE PROTECTION to prevent damage
from sharp objects and/or caustic liquids.
ONLY OPERATE TESTS IN A WELL-VENTILATED AREA since the
vehicle produces carbon monoxide when the engine is running.
DO NOT TOUCH HOT ENGINE PARTS to prevent severe burns. The
motor's parts can get extremely hot when the engine is running.
ALWAYS BE AWARE OF MOVING PARTS (such as coolant fans, pulleys,
belts, etc.) since they spin or turn at high speeds when the engine is
running.
READ ALL INSTRUCTIONS BEFORE USING
EN I 4
DO NOT CUT THE PRODUCT'S CORDS OR SUBMERGE THEM IN
WATER. The product is an electrical device that can cause shock and
severe burns.
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.
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 burns or electric shock if it contacts electricity.
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.
DON'T SMOKE OR HAVE ANY FLAMES NEAR THE VEHICLE when
testing. Fuel and battery vapors are highly ammable.

ABOUT THE BT100W
SECTION 1 WHAT'S IN THE BOX?
The BT100W is a battery tester that applies the most advanced conductance testing
technology and incorporates reverse polarity protection. It is designed to help
technicians locate faults quickly by taking accurate measurements of the vehicle
battery's actual Cold Cranking Amps (CCA) and State of Health (SOH), as well as
testing the cranking system and charging system. With it, users can perform any of
the tests on the tester itself or on an APP through their phone.

SECTION 3 GETTING STARTED
Cars are powered by lead-acid batteries. The most commonly used ones are listed
below:
Let's take the following picture as an example (See Figure 3.2.1):
Figure 3.2.1
●
Flooded Lead Acid Batteries (Wet):
This is the oldest/most common car battery type, also known as a "SLI battery."
The Flooded Battery is usually made of 6 cells with a liquid electrolyte solution
of sulfuric acid and water that needs to be topped off periodically. This battery
typically supplies a voltage of 12.6V at full charge.
●
Enhanced Flooded Battery (EFB):
This battery type also uses a liquid electrolyte solution. However, different from the
Wet Flooded Lead Acid, it is sealed and maintenance-free. The Enhanced Flooded
battery is usually seen in cars with simple start-stop technology, and can provide
up to 85,000 engine cranks.
●
Gel Cell Battery (Gel) & VRLA Battery:
Gel batteries are similar to ooded batteries. Although for this type, calcium
replaces the antimony in the lead plates, and silica is added to the electrolyte
solution, turning the liquid into a gel.
●
Absorbent Glass Mat Battery (AGM):
AGM batteries are designed to deliver powerful bursts of starting amps and run
for a long time. "Absorbed Glass Mats" are used to cushion the ultra-thin lead
plates, allowing manufacturers to include more leads into one battery and provide
more power. AGM batteries are divided into two categories according to the cell
structure. They can be AGM FLAT PLATE or AGM SPIRAL. This type of battery
is ideal for vehicles with automatic start-stop applications and braking energy
recovery.

Type
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 3.3.1.
2) To balance uneven weight distribution, some manufacturers hold the engine in
the trunk. See battery location
⑤
,
⑥
, and
⑦
in Figure 3.3.1. 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 3.3.1.
4) For other vehicles, the battery can be located underneath the passenger seat. See
battery location
③
in Figure 3.3.1
Figure 3.3.1
1) Reserve Capacity: 80Ah
The Reserve Capacity is a time measurement that explains how long a fully-
charged battery can deliver a 25 amps current in an 80°F environment before the
battery is discharged and drops to 10.5V.
2) Battery Type: AGM
3) Voltage: 12V
When fully charged, automotive batteries should measure at 12.6V. However, this
measurement should be from 13.7 to 14.7V when the engine is running. If the
battery tester 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.
4) CCA: 650A (SAE)
The CCA rating refers to how many amps a 12V battery can deliver at 0°F in 30
seconds while maintaining at 7.2V at least. This means that the higher the CCA
rating is, the easier the engine can be cranked in cold temperatures.
3.3 Where Is the Battery of a Car Located?
EN I 9
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 3.3.2) to make
jumpstarting easier. However, to ensure data accuracy and operation safety, DO NOT
CONNECT THE BATTERY TESTER TO THE JUMPSTART POSTS.
Figure 3.3.2
Figure 3.4.1
1) Before connecting the clamps to the terminals, please use sandpaper to polish
off any corrosion on the battery terminals. With this, you can avoid inaccurate test
values.
2) Attach the red clamp to the positive (+) terminal and the black clamp to the
negative (-) (See Figure 3.4.1).
• 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.
3.4 Connect the Clamps to the Battery Terminals.

For any of the tests (either via the device or APP), clamps must be connected
securely to the corresponding terminal, that is, black to the negative terminal (-) and
red to the positive terminal (+) (See Figure 3.4.1). After the connection is made, the
BT100W will automatically start and display the interface as shown below (See Figure

Charging Ripple: A vehicle's battery operates
on one-way direct current (DC) electricity, while
alternators output alternating current (AC)
electricity. In this process, the power needs to
go through the diode rectier to turn into a
direct current - that's when the ripple occurs.
