Battery Diagnostics Made Simple—and Fast

The BT300P delivers clear results in seconds with a simple, guided interface that anyone can use. No training, no guesswork—just fast, accurate diagnostics that help you confirm battery health and move on with confidence.

One Tester for Every 12V Battery

From Flooded to AGM, GEL, and EFB batteries, the BT300P handles them all. With support for 10 international standards—including CCA (100–2000), EN, DIN, JIS, and SAE—you can test virtually any 12V battery with professional precision.

Complete Testing for a Clear Battery Diagnosis

The BT300P runs four essential tests to give you a full picture of battery and system performance:
-CCA Value: Confirms actual Cold Cranking Amps (100–2000 CCA) for real-world starting power.
-State of Health (SoH): Evaluates overall battery condition and remaining life.
-Cranking System: Checks the starting system to identify weak batteries or starter issues early.
-Charging System: Measures alternator output and charging efficiency to ensure balanced performance.

Certified Accuracy You Can Trust

The BT300P meets major global standards—CCA, CA, BCI, MCA, DIN, IEC, EN, SAE, JIS, and GB—delivering precise, repeatable results across Flooded, AGM, GEL, and EFB batteries. Wherever you test, you can count on professional-grade accuracy and consistency.

Print, Share, and Save Test Results on the Spot

Give every test a professional finish. The BT300P’s built-in thermal printer lets you generate clear, detailed reports in seconds, making it perfect for customer documentation or tracking performance over time, without computers, extra cables, or hassle.

Full-Color Readouts That Simplify Every Test

The BT300P’s bright 2.4-inch color display shows every reading clearly, even in dim garages or bright sunlight. Sharp graphics and easy-to-read data help you confirm results faster and make confident decisions with every test.

Safe, Smart Testing Every Time

Connect with confidence, without worrying about sparks or damage. The BT300P’s reverse polarity protection safeguards both the tool, the user, and the vehicle, while advanced conductivity technology ensures every result is accurate, consistent, and reliable.

Lightweight Design. Heavy-Duty Performance.

Weighing just over one pound, the BT300P is easy to carry yet built to last. Its rugged housing and responsive performance make it tough enough for shop floors, mobile calls, and everything in between, ensuring you’re always ready when the job calls.

    Great Battery Tester - Great Results

    Had a friend with a battery that had a "Chia Pet" on his battery terminals. Used the BT300P, and it tested weak with a "Replace Battery" warning. Used the BG battery cleaner so it would have a better connection on the terminals. Once the battery was cleaned, tested again, and the battery tested "Good Battery" and had a 100% health. I did the test to see the difference in results and see if the BT300P would pick it up AND IT DID! Very good and smart battery tester.
