best car battery tester 2019: Your Questions Answered

Q1: Why should I buy a car battery tester?

A: A car battery tester helps you monitor your vehicle’s battery health, charging system, and cranking system. This allows you to identify potential issues early, preventing unexpected breakdowns and saving you from costly roadside assistance or premature battery replacements. It’s a key tool for proactive vehicle maintenance.

Q2: What’s the difference between a battery test, a cranking test, and a charging test?

A: A battery test assesses the battery’s overall health, voltage, and state of charge. A cranking test evaluates the starter motor and battery’s ability to start the engine. A charging test checks if your alternator and charging system are working correctly to replenish the battery while the engine is running. These tests combined give you a full picture of your electrical system’s performance.

Q3: Can these testers work on different types of batteries, like AGM or Gel?

A: Yes, most modern car battery testers, including many of the “best car battery tester 2019” models reviewed, are compatible with various 12V battery types. Look for specifications that mention support for Flooded, AGM (flat plate and spiral), EFB, and GEL batteries. Always double-check the product description for specific compatibility.

Q4: Are these battery testers difficult to use for a beginner?

A: Not at all! Many car battery testers are designed with user-friendliness in mind. Models like the MOTOPOWER MP0514A are “plug-and-test” and very intuitive. Others, like the ANCEL BA101 and TOPDON BT100, feature clear LCD screens and menu-driven interfaces, making them accessible even for novice users.

Q5: What does CCA mean, and why is it important for a battery tester?

A: CCA stands for Cold Cranking Amps, which is a rating used to define a battery’s ability to start an engine in cold temperatures. It indicates the amount of current a 12V battery can deliver at 0°F (-18°C) for 30 seconds while maintaining a voltage of at least 7.2 volts. Most car battery testers require you to input the CCA value from your battery’s label for an accurate health assessment, as it’s a key indicator of its cranking power.

Q6: Can a car battery tester tell me if my alternator is faulty?

A: Yes, many advanced car battery testers include a charging system test (or alternator test) specifically designed to check the alternator’s output. These tests can help you determine if your alternator is overcharging, undercharging, or not charging at all, which are common issues that can lead to battery problems.

Q7: Is it worth investing in a 12V/24V compatible tester if I only have a car?

A: If you only own a standard 12V car, a dedicated 12V tester might be more cost-effective. However, if you anticipate owning larger vehicles like trucks, RVs, or even some boats in the future, or if you plan to help friends with various vehicles, investing in a 12V/24V load tester like the TOPDON BT200 offers greater versatility and future-proofing for your automotive diagnostic tools.
