BA101 Plus Car Battery Tester

Key Features

• Upgraded BA101 for 6V & 12V Batteries: ANCEL BA101 Plus keeps the trusted BA101 battery testing experience and adds wider 6V/12V lead-acid battery support. Test Regular Flooded, AGM Flat Plate, AGM Spiral, GEL and EFB batteries from 20-2000 CCA, including CCA, voltage, internal resistance, SOH and SOC
• Battery, Cranking & Charging System Check: More than a basic voltage meter, this automotive battery tester checks battery health, cranking voltage and charging system status, including load/unload voltage and ripple voltage. It helps identify weak batteries, abnormal cranking voltage or possible alternator charging issues before they lead to no-start problems
• See Results Clearly & Track Battery History: The 2.8-inch color TFT screen makes test results easier to read in the garage, shop or driveway. View real-time voltage curves and replay up to 120 seconds of data to spot voltage drops during cranking or charging checks. Store up to 1,400 records to compare battery condition over time or review tests for multiple vehicles
• Fn One-Touch Test, Safer DIY Use: Press the Fn shortcut key to start a quick battery test without searching through menus, saving time when checking multiple vehicles or batteries in the garage, driveway, repair shop or battery counter. Built-in reverse polarity, short circuit, overcurrent and overvoltage protection help reduce operation mistakes, while durable insulated clips provide stable contact
• Wide Vehicle Use, Lead-Acid Only: Designed for 6V and 12V lead-acid batteries in cars, trucks, motorcycles, SUVs, ATVs, boats, RVs, lawn mowers and golf carts. Not compatible with lithium, LiFePO4 or 24V battery systems. For best results, enter the correct battery type, standard and rated CCA value from the battery label
• Trusted ANCEL BA101 Series: Built on the market success of the ANCEL BA101 battery tester, BA101 Plus continues the simple, reliable testing experience valued by mechanics, battery service providers and DIY users. With practical upgrades inspired by real-world use, including 6V/12V battery support, a color display, voltage curve review, test records and Fn one-touch quick testing, BA101 Plus is designed to make battery checks faster, clearer and easier
• Driver Installation for Printing: To use the printing function, you need to install the printing software designed specifically for this tester on your PC. Since it is a dedicated program for our product, it is temporarily not listed in mainstream security databases. This may trigger a standard safety alert from Windows Defender or other antivirus software — this is completely normal. The software is 100% secure. Simply select "Allow", "Trust", or "Run" to proceed with the installation
