Product description
Battery tester for extreme temperatures
Car batteries usually last three to five years but can die suddenly. Even if your battery appears charged, it could be weak. Warm weather and regular driving can conceal this, but cold temperatures or neglect can lead to starting issues. It's crucial to get a battery test with a BA101 to be sure.
-
The AH value is required (from your battery label). If it's missing, choose the 'Battery Test' menu.
-
Select correct parameters (Type, CCA Rating). Attach clamps to terminals or as close as possible.
-
Ensure correct clamp connection, clean terminals, and verify battery voltage before testing.
-
Ensure normal battery voltage and turn off unnecessary electrical loads for more accurate testing.
Winter shouldn’t surprise you with car battery problems! Say goodbye to uncertainty with the BA101. When winter hits, your car battery’s condition can become unpredictable. By the end of the season, you’re left wondering. BA101 offers a quick, accurate test to remove all the guesswork

3 Reasons to Stop Checking Your Car’s Battery with a Multimeter
Charge Retention: Multimeters may give false readings as car batteries can hold a charge even when their capacity is low.
Low Load Impact: Multimeters have high impedance, putting minimal load on the battery and leading to inaccurate voltage readings.
Better Options: Dedicated battery testers like BA101 with lower impedance provide more reliable results than standard multimeters, ensuring accurate assessments of battery health.

Common Mistakes to Avoid When Using a Car Battery Tester
When using a car battery tester, here are some common mistakes to avoid: incorrect connections, poor battery contact, wrong parameters (such as inputting the wrong battery type or cca), testing immediately after turning off the engine, leaving electrical loads on, skipping the charging system test, and not testing according to the battery's capacity. Being aware of these mistakes will help ensure more accurate and reliable test results.

-
Does this tester work with 6V or 24V batteries?
No, this tester is designed for 12V lead-acid batteries (30–200Ah). It does not support lithium, 6V (below 30Ah), or 24V systems. For 6V or 24V testing, consider the BA101 Pro or Plus, with Plus supporting 6V+12V and Pro supporting 12V+24V
-
Is this tester powered by a built-in battery?
No. Like most car battery testers, it is powered by the vehicle’s 12V battery during testing for more accurate results. Testers with built-in batteries are typically basic voltage/esistance testers and not intended for automotive system diagnostics.
-
How can I get the most accurate test results?
For best accuracy, make sure the correct battery type, battery standard, and CCA rating are selected. Always connect the clamps directly to the battery terminals. For stable results, test the battery after the engine has been off for about 2 hours.
-
Do I need to remove the battery from the vehicle to test it?
No. The battery can be tested directly on the vehicle, making routine checks faster and more convenient. Our tester offers two modes: “battery in vehicle” and “battery out of vehicle.” You can choose the mode that best fits your testing situation
-
Is this tester safe to use?
Yes. It is built with reverse polarity protection and high-performance power cables to ensure safe and reliable testing, helping protect both the tester and the vehicle’s electrical system during use
- Catch Battery Problems Early: Featured in two videos by Project Farm, a popular YouTube channel with millions of subscribers, the ANCEL BA101 helps you quickly spot battery issues before they leave you stranded. It provides easy-to-understand readings for State of Health (SOH), State of Charge (SOC), voltage, current, CCA, plus cranking and charging system tests, so you can better understand your battery and help avoid unexpected breakdowns
- Know the Real Condition: Don’t let inaccurate readings lead to costly surprises. Built with high-quality copper crocodile clips and a precision smart chip, this battery tester is designed to deliver dependable results. For the most accurate test, enter the correct battery type, rating value (such as CCA/Ah), and temperature exactly as shown on your battery label, so you get a clearer picture of your battery’s true condition
- Fast, Clear, Hassle-Free Testing: The classic black-and-white screen, adjustable contrast, and white backlight make results easy to read in bright sunlight or low-light conditions. One-handed operation keeps testing simple, while direct power from your vehicle’s battery means no charging and no internal batteries to deal with. Multi-language support makes it easier for more users to test with confidence
- Protection When Mistakes Happen: Built-in 4-in-1 protection helps guard against reverse polarity, short circuits, overcurrent, and overvoltage for safer testing, especially in tight spaces where clamp slips or wiring mistakes can happen. The 3x reinforced ABS housing adds extra durability and helps protect both the tester and your battery during everyday use
- Built for More 12V Batteries: Supporting global standards including JIS, EN, DIN, SAE, BCI, GB, CA, MCA, and IEC, this tester works with 12V batteries used in cars, trucks, boats, RVs, ATVs, lawnmowers, golf carts, and motorbikes over 30Ah. Compatible with Flooded, AGM, GEL, and EFB batteries. Not for lithium batteries, non-12V batteries (6V/8V/24V), or motorcycles below 30Ah. For 6V testing, choose BA101 Plus. For 24V testing, choose BA101 PRO
