6V, 12V BT300 Car Battery Tester, 5-3000 CCA Car Batteries, Starter and Alternator, Starting System Load Analyzer for Vehicles, Trucks, SUVs, Boats -

【CHARGE AND STARTING TESTS】 The BT300 car battery condition tester and alternator tester can also perform: √a starting test of the vehicle's starter motor to check if it starts correctly, √a charging test of the alternator to prevent overcharging or incomplete charging. Note: Please turn off all electrical devices (such as air conditioning, headlights, stereo, or any other electrical equipment) during the charging test. 【WIDE COMPATIBILITY】 The BT300 battery charge tester works on all 6V and 12V batteries with CCA ratings of 5-3000, including flooded lead-acid (VRLA or SLA)√ AGM√ GEL√ SLA√ STANDARD LSI batteries for cars√ light trucks√ SUVs√ vans√ motorcycles√ RVs√ ATVs√ trailers√ boats√ yachts√ lawnmowers and more. Our 12V car battery tester allows you to quickly adjust the CCA to ±5 or ±50 rather than just ±50. NOTE: Does NOT work on lithium batteries. 【ONE-CLICK VOLTAGE AND BATTERY TEST】 When you start the battery test, the real-time voltage is displayed as a waveform graph as quickly and accurately as possible. The BT300 vehicle battery tester gives you a detailed view of all output variations. Note: This battery analyzer can work on both vehicle and off-vehicle batteries. 【PLUG & PLAY, EASY TO USE, AND VISUAL LED INDICATOR】 The BT300 battery and alternator tester is plug-and-play, equipped with a large, easy-to-read 2.8-inch HD TFT screen and a single button to test/check/display the battery waveform, allowing you to start working directly as needed. Additionally, helpful LED indicators visually display the battery's health status (green: good, yellow: normal, red: bad) and support 12 languages. 【6V 12V BATTERY TESTER FOR CAR, MOTORCYCLE, TRUCK, QUAD, ATV, AND BOAT】 The BT300 is a fast and accurate battery tester that performs virtually all the necessary tests to check the health of your vehicle's battery before it dies or a jump starter is needed, including 6V and 12V battery tests such as voltage, charge, internal resistance, ripple test, rated power, SOC, SOH, CCA test, load test, and cranking test. It's an essential battery testing tool for DIYers and professionals alike. 【FAST TEST RESULTS WITH 99.5% ACCURACY】 The BT300 car battery tester performs battery tests efficiently and provides reliable results with over 99.5% accuracy. Test results can be saved and viewed directly on the screen. To print the data, simply connect the battery tester to a computer.
