FAQ

Q: Can BT300P test the battery installed in the vehicle?
A: Yes, it supports in-vehicle and out-of-vehicle testing.
Q: Is the test result accurate?
A: Yes. Our BT300P features advanced conductance detection giving you accurate test results in seconds.
Q: What batteries can BT300P 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.
Q: Is BT300P 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.
Q: 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.
Q: 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.
