Product Description

digital battery tester

Dual Testing Modes: Quick & Precise Test

Quick Test: Ideal when cold cranking amp (CCA) parameters are unknown. Evaluates battery startup capacity based on general battery capacity (3Ah-250Ah).

Precise Test: Input exact cold start current values (CCA, EN, IEC, DIN, JIS) for ultra-accurate battery health (SOH) and state of charge (SOC) judgment.

Frequently Asked Questions

Why is the battery voltage reading higher than normal right after stopping the car?

Immediately after the vehicle engine is turned off, the battery is fully charged and holds a surface charge. For accurate results, turn on the car headlights for about 3 minutes to dissipate surface voltage, then perform the test once voltage stabilizes.

What should I do if the tester prompts a poor clip contact warning?

Clean any rust, dirt, or oxidation off the battery terminals before attaching the clamps. Ensure both sides of each clamp make solid metal-to-metal contact with the battery posts.

Can this unit test both 12V and 24V vehicle electrical systems safely?

Yes, the device is designed for 12V and 24V lead-acid batteries with an integrated over-voltage protective range spanning from 9V up to 35V DC, meeting strict CAT III 300V safety guidelines.

What is the primary difference between Quick Test and Precise Test?

Quick Test allows evaluation based solely on battery rated capacity (Ah) when cold cranking amps are not marked. Precise Test requires you to input designated battery standard values (CCA, DIN, IEC, EN) for exact health analysis.

How do I export diagnostic data from the tester?

The tester generates an on-screen QR Code containing all key diagnostic parameters. You can scan this code with a mobile device to easily view, store, and export diagnostic records.
