ANCEL BT310 12V 24V Car Battery Tester 100-2000 CCA Battery Load Tester for Lead-Acid & Lithium Batteries, Digital Analyzer Tests Cranking & Charging, Compatible with Car Truck Motorcycle ATV Boat

[Great-Value Battery tester]: ANCEL BT310 is an all-in-one solution for 12V & 24V lead-acid and lithium batteries, eliminating the need to purchase multiple testers. It supports Flooded, AGM, GEL, and EFB battery types and works with cars, SUVs, light trucks, motorcycles, ATVs, lawn mowers, and boats. Easily diagnose battery health, cranking, and charging systems to maintain peak performance and avoid unexpected failures, even in winter
[Professional-Grade Accuracy]: ANCEL battery tester delivers up to 99.98% testing accuracy with clear SOC, SOH, voltage, and internal resistance readings to assess true battery health. It also measures cranking voltage and time, plus charging system performance under load, no-load, and ripple conditions—helping identify whether issues come from the battery, starter, or alternator. It supports all major standards including CCA/BC/CA/MCA/JIS/DIN/IEC/EN/SAE/GB to avoid result variations across different battery ratings
[Easy to Use & Understand]: Ready to use out of the box with no charging or technical knowledge required. Simply connect the clamps, select the battery type, and enter the CCA value (usually on the battery label) to start testing. Within seconds, the battery load tester displays one of 5 clear results: GOOD BATTERY, GOOD-RECHARGE, CHARGE & RETEST, REPLACE BATTERY, or BAD CELL-REPLACE, so you know exactly what action to take. The backlit LCD with adjustable contrast ensures clear visibility in bright sunlight or dark garages. (Note: The bottom port is for factory use only)
[Enhanced Safety Protection]: Multiple built-in protections—including reverse polarity, short-circuit, overvoltage, and over-temperature—help prevent damage during battery testing. If the clamps are connected incorrectly, power is automatically cut off to protect the tester and the vehicle’s electrical system. A newly added silicone protective case adds an extra layer of durability against drops and daily wear
[Compact & Portable Design]: A compact, all-in-one body keeps battery testing easy to carry and ready to use. The car battery tester fits neatly into a toolbox, glove box, or drawer, so it’s always close at hand when needed. From quick checks at home to unexpected situations on the go, reliable testing stays within reach
[Reliable in Any Season]: Reliable battery testing stays available all year, within a temperature range from -4°F to 158°F, so seasonal temperature changes don’t interrupt testing. Performance stays consistent from colder to warmer months, helping results remain dependable whenever batteries need to be checked
[Multi-Language Interface]: Six language options make the interface practical for users across different countries and regions. English, Français, Español, Deutsch, Italiano, and Português are supported, so menus and test results stay clear in a familiar language. This helps users understand battery status faster and decide what to do next, without guesswork
