Safety Information
For your own safety and the safety of others, and to prevent damage to the device and
vehicles upon which it is used, it is important that the safety instructions presented
throughout this manual be read and understood by all persons operating or coming into
contact with the device.
There are various procedures, techniques, tools, and parts for servicing vehicles, as well
as in the skill of the person doing the work. Because of the vast number of test applications
and variations in the products that can be tested with this equipment, we cannot possibly
anticipate or provide advice or safety messages to cover every circumstance. It is the
automotive technician’s responsibility to be knowledgeable of the system being tested. It
is crucial to use proper service methods and test procedures. It is essential to perform
tests in an appropriate and acceptable manner that does not endanger your safety, the
safety of others in the work area, the device being used, or the vehicle being tested.
Before using the device, always refer to and follow the safety messages and applicable
test procedures provided by the manufacturer of the vehicle or equipment being tested.
Use the device only as described in this manual. Read, understand, and follow all safety
messages and instructions in this manual.
Safety Messages
Safety messages are provided to help prevent personal injury and equipment damage. All
safety messages are introduced by a signal word indicating the hazard level.
DANGER
Indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury to the operator or to bystanders.
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in death or
serious injury to the operator or to bystanders.
Safety Instructions
The safety messages herein cover situations Autel Intelligent Technology Corp., Ltd. is
aware of. Autel Intelligent Technology Corp., Ltd. cannot know, evaluate or advise you as
to all of the possible hazards. You must be certain that any condition or service procedure
encountered does not jeopardize your personal safety.

iii
DANGER
When an engine is operating, keep the service area WELL VENTILATED or attach a
building exhaust removal system to the engine exhaust system. Engines produce carbon
monoxide, an odorless, poisonous gas that causes slower reaction time and can lead to
serious personal injury or loss of life.
SAFETY WARNINGS
Wear safety glasses and protective clothing.
NEVER smoke or allow a spark or flame in vicinity of battery or engine.
Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing
or eyes.
If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters eye, immediately flush eye with cold running water for at least ten minutes and
get medical attention immediately.
Use caution when working with metallic tools to prevent sparks or short circuits.
Remove any jewelry or watches before you start servicing the battery.
Keep hair, hands, and clothing as well as tester leads and cords away from moving
blades and belts.

2 General Introduction
OTOFIX BT1 Lite
Smart Battery Tester
The BT1 Lite is a battery and cranking/charging system analysis tool that uses
Adaptive Conductance, an advanced battery analysis method to produce a
more accurate examination of the battery’s cold cranking ability and reserve
capacity, vital to determining a battery’s true health. The BT1 Lite enables
technicians to view the health status of the vehicle's battery and
cranking/charging system. Download the free and easy-to-use Battery Test
mobile app that is available for iOS and Android devices. Together with the BT1
Lite, this app can complete battery & cranking and charging system tests and

9 Maintenance and Service
To ensure that your OTOFIX tester performs at its optimum level, we advise
that the product maintenance instructions discussed in this section are read and
followed.
9.1 Maintenance Instructions
Maintain the device with the following precautions and guidance in mind.
Do not use any abrasive cleansers, detergents, or automotive chemicals
on the tester.
Maintain all devices in dry conditions and keep them within normal
operating temperatures.
Do not store the devices in humid, dusty or dirty areas.
Check the housing, wiring, and connectors for dirt and damage before
and after each use.
At the end of each work day, wipe the device housing, wiring, and
connectors clean with a damp cloth.
Do not attempt to disassemble the tester.
Do not drop or cause severe impact to the device.
Use only authorized battery chargers and accessories. Any malfunction
or damage caused by the use of unauthorized battery chargers and
accessories will void the product warranty.
Ensure that the battery charger does not come in contact with conductive
objects.

33
9.2 Troubleshooting Checklist
A. When the tester does not work properly:
Ensure the tester has been registered.
Ensure tool’s firmware is upgraded.
Check all cables, connections, and indicators to ensure proper
communication between tool and vehicle and battery.
B. When you are unable to charge the tester:
Check the connections.
Ensure you are using the power supply included with the tool.
Ensure the tool is being charged in a room of moderate temperature, not
too hot or too cold.
Contact technical support or your authorized OTOFIX supplier if the unit
or charger is damaged.
C. When Bluetooth connection fails:
The Bluetooth signal is out of range. Move the battery tester closer to
your mobile device.
On your mobile device, turn Bluetooth off and then on.
Power your mobile device off and then on.
NOTE
Contact OTOFIX technical support or your authorized OTOFIX supplier if the
problem persists.

34
9.3 About Battery Usage
Your tester is powered by a built-in Lithium-ion Polymer battery. This means
that, unlike other battery technologies, the battery can be recharged with some
remaining battery life without damaging its longevity.
DANGER
1. The built-in Lithium-ion Polymer battery is factory replaceable only;
incorrect replacement or tampering with the battery pack may cause
an explosion.
2. Do not use a damaged battery charger.
Do not disassemble or open, crush, bend or deform, puncture or shred.
Do not modify or remanufacture, attempt to insert foreign objects into
the battery, expose to fire, explosion or other hazards.
Make sure to only use the charger and USB cables that are supplied
with the tool. The use of other chargers and/or USB cables might result
in malfunction or damage to the tool.
Only use the charging device that has been qualified with device per
the standard. Use of an unqualified battery or charger may present a
risk of fire, explosion, leakage, or other hazards.
Avoid dropping the tester. If the tester is dropped, especially on a hard
surface, and the user suspects damage, contact OTOFIX technical
support.
The battery recharging time varies depending on the remaining battery
capacity.
Battery life inevitably shortens over time.
Overcharging may shorten battery life. Remove the tester from its
charger once it is fully charged. Unplug the charger once charging is

35
complete.
Ensure the tool is stored in a dry and moderate temperature area.
Extreme heat or cold may result in damage to the tool and/or its battery.
