Check compatible batteries in cars, trucks, motorcycles, RVs, ATVs and boats—one tool for routine checks across multiple vehicles.
✓4-IN-1 BATTERY, CRANKING & CHARGING TESTS: Slow starts as colder weather approaches? This 12V/24V automotive battery tester checks battery health, starting performance and charging system operation. View cranking voltage and time, charging voltage and ripple readings. Check before winter commutes or road trips to help spot issues that need attention.
✓UP TO 99.98% TESTING ACCURACY — TEST BEFORE YOU REPLACE: A slow start doesn’t automatically mean you need a new battery. This ANCEL battery tester combines a precision smart chip with high-quality copper clamps to help you assess battery condition. Test before replacing to help avoid unnecessary purchases and save money, or check a newly purchased battery before installation.
✓FIVE CLEAR RESULTS — KNOW YOUR NEXT STEP: New to battery testers? The BT310 provides five clear status messages: GOOD BATTERY, GOOD-RECHARGE, CHARGE & RETEST, REPLACE BATTERY or BAD CELL-REPLACE. View SOH, SOC, voltage, CCA and internal resistance on the 128×64 backlit LCD. Adjustable contrast helps you read the results in the garage.
✓EASY-TO-USE BATTERY LOAD TESTER — NO CHARGING REQUIRED: The BT310 12V battery tester also supports 24V systems and draws power from the battery under test. Connect the clamps, select the battery type and enter its labeled rating, then follow the screen prompts. Supports CCA, BCI, CA, MCA, JIS, DIN, EN, SAE, IEC and GB standards, with rated capacities of 30–220 Ah under GB.
✓SAVED TEST HISTORY — REVIEW AND COMPARE: Reopen saved Battery, Cranking and Charging reports through the Review Data menu. Compare readings before and after charging or between routine checks to see whether battery condition has changed. Review previous results without relying on memory alone.
✓FOUR BUILT-IN PROTECTIONS — CONNECT WITH CONFIDENCE: Built-in reverse-polarity, short-circuit, overvoltage and over-temperature protection helps reduce risks from incorrect connections and electrical faults. Incorrect connections trigger automatic power cutoff to help protect the tester and vehicle electrical system. A reinforced silicone case adds durability, while the 800 mm (31.5-inch) cable makes positioning easier. Includes ANCEL’s 1-year limited warranty.
