SAFETY IS ALWAYS THE FIRST PRIORITY!

READ ALL INSTRUCTIONS BEFORE USING

For your safety, the safety of others, the product, and the vehicle you are working on, PLEASE, CAREFULLY READ AND MAKE SURE YOU FULLY UNDERSTAND ALL THE SAFETY INSTRUCTIONS AND MESSAGES ON THIS MANUAL.

ONLY OPERATE THE TEST IN A WELL-VENTILATED AREA since the vehicle produces carbon monoxide, a toxic and poisonous gas, and particulate matter when  the engine is running.

ALWAYS WEAR APPROVED SAFETY EYE PROTECTION to prevent damage from sharp objects and caustic liquids.

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 engine parts become very hot when the engine is running.

ALWAYS SHIFT THE GEAR TO P (FOR AUTOMATIC TRANSMISSION) OR TO NEUTRAL (FOR MANUAL TRANSMISSION) AND MAKE SURE THE PARKING BRAKE IS ENGAGED.

ALWAYS USE A DIGITAL MULTIMETER WITH AT LEAST 10 MEGOHMS OF IMPEDANCE when conducting electrical tests on vehicles to prevent causing damage to on-board electronic components.

NO SMOKING ANYWHERE NEAR THE VEHICLE when testing. The fuel and battery vapors are highly flammable.

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 causes severe burn or electric shock if it contacts with 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.

Battery acid is extremely corrosive. If acid gets into your eyes, FLUSH THEM THOROUGHLY WITH COLD RUNNING WATER FOR AT LEAST 20 MINUTES AND SEEK MEDICAL ATTENTION IMMEDIATELY. If battery acid gets on your skin or clothing, WASH IT IMMEDIATELY WITH A SOLUTION OF WATER AND BAKING SODA.

FAQ

Q1: Can BT50 test the battery installed in the vehicle?

A : Yes, it supports in-vehicle and out-of-vehicle testing.

Q2: Is the test result accurate?

A : Yes. Our BT50 features advanced conductance detection, able to give you accurate test results in seconds.

Q3: What batteries can BT50 work on?

A : It works on 12V regular flooded, AGM Flat plate, AGM Spiral, GEL and Deep Cycle batteries, with CCA between 100 to 2000.

Q4: Is BT50 designed with any built-in protections?

A : Yes. It offers peace of mind with extra-safe Reverse Polarity and Spark proof protection, and easy operations even if you’re new to battery testing.

Q5: How do I confirm if my vehicle battery is bad or good?

A : The battery tester will display SOH (State of Health), SOC (State of Charge), CCA (Cold Cranking Ampere), Voltage, Internal Resistance, and Rating, with an intuitive test result of “GOOD” or “BAD” for your reference. If the internal resistance is too large, it indicates a broken battery.

Q6: Can this battery tester estimate the remaining capacity of my battery?

A : Yes. The battery tester will display SOC (State of Charge) to express as a percentage of your battery’s rated capacity, a measure of its condition to assess the potential energy.
Note that a decent SOC (State of Charge) doesn’t mean the battery is in good condition. You need to refer to your battery’s actual CCA Value and Internal Resistance for further analysis.
