## Features

- 𝗖𝗔𝗥 𝗪𝗢𝗡’𝗧 𝗦𝗧𝗔𝗥𝗧? 𝗙𝗜𝗡𝗗 𝗧𝗛𝗘 𝗖𝗔𝗨𝗦𝗘 𝗕𝗘𝗙𝗢𝗥𝗘 𝗥𝗘𝗣𝗟𝗔𝗖𝗜𝗡𝗚 𝗣𝗔𝗥𝗧𝗦 - A slow crank, no-start, or battery that keeps dying does not always mean the battery itself is bad. Built on FOXWELL’s BT705 platform, the BT780 automotive battery tester checks battery health plus 12V/24V cranking and charging systems to help narrow down whether the problem is the battery, starting system, or charging system. Test 100–2000 CCA batteries and use the results to decide whether the battery can keep working, needs charging, or may need replacement instead of guessing and changing the wrong part
- 𝗧𝗘𝗦𝗧 𝗜𝗧. 𝗣𝗥𝗜𝗡𝗧 𝗜𝗧. 𝗦𝗛𝗢𝗪 𝗪𝗛𝗔𝗧 𝗬𝗢𝗨 𝗙𝗢𝗨𝗡𝗗. - The BT780 battery tester with built-in thermal printer lets you turn a test result into something you can actually hand over, explain, and keep. Print directly from the tester with no app, Bluetooth, or subscription required. Show a customer the result on the spot, keep a paper copy for future comparison, or use the report during repair discussions instead of relying on a verbal explanation or a number on the screen. Includes 3 rolls of thermal paper
- 𝗕𝗨𝗜𝗟𝗧-𝗜𝗡 𝗕𝗔𝗧𝗧𝗘𝗥𝗬. 𝗠𝗢𝗥𝗘 𝗙𝗟𝗘𝗫𝗜𝗕𝗟𝗘 𝗧𝗘𝗦𝗧𝗜𝗡𝗚. - Many basic car battery testers rely entirely on the battery under test for power. The BT780 has its own internal battery, so you can power on the tool before connecting, navigate menus, review information, and print results without depending completely on the tested battery. That is especially useful when working with a weak or low-voltage battery and gives you a more practical workflow during repeated testing
- 𝗟𝗢𝗢𝗞 𝗕𝗘𝗬𝗢𝗡𝗗 𝗩𝗢𝗟𝗧𝗔𝗚𝗘 𝗔𝗡𝗗 𝗔 𝗦𝗜𝗠𝗣𝗟𝗘 𝗚𝗢𝗢𝗗/𝗕𝗔𝗗 𝗥𝗘𝗦𝗨𝗟𝗧 - A battery can show voltage and still have poor starting capability. The BT780 displays measured CCA, voltage, internal resistance, SOC, SOH, and battery test results so you have more information to understand actual battery condition before deciding what to do next. Printed reports can also include shop name, technician ID, and battery serial number, making it easier to identify the battery tested, explain the findings, and compare results before and after charging or service
- 𝗕𝗨𝗜𝗟𝗧 𝗙𝗢𝗥 𝗢𝗡𝗘-𝗣𝗘𝗥𝗦𝗢𝗡, 𝗥𝗘𝗔𝗟-𝗪𝗢𝗥𝗟𝗗 𝗧𝗘𝗦𝗧𝗜𝗡𝗚 - A 6.5 ft reinforced test cable gives you more room to work around the vehicle and makes it easier for one person to connect, operate the tester, and review results. The 3.2-inch LCD keeps key data easy to read, heavy-duty clamps provide secure terminal contact, and the protective housing plus hard carrying case help keep the tester and accessories protected and organized between jobs. A practical setup for repair shops, battery stores, mobile mechanics, fleets, and serious home garages
- 𝗖𝗛𝗘𝗖𝗞 𝗬𝗢𝗨𝗥 𝗕𝗔𝗧𝗧𝗘𝗥𝗬 𝗧𝗬𝗣𝗘, 𝗥𝗔𝗧𝗜𝗡𝗚 𝗔𝗡𝗗 𝗦𝗬𝗦𝗧𝗘𝗠 𝗕𝗘𝗙𝗢𝗥𝗘 𝗕𝗨𝗬𝗜𝗡𝗚 - The FOXWELL BT780 battery analyzer supports 100–2000 CCA Flooded, AGM Flat Plate, AGM Spiral, EFB, GEL, and compatible Start-Stop starting batteries, along with CCA, CA, MCA, JIS, DIN, IEC, EN, and SAE rating standards. It is designed for battery testing across cars, pickups, trucks, RVs, motorcycles, marine applications, fleets, and commercial vehicles. Confirm your battery type, rating, and supported electrical system before use. NOTE: Deep-cycle batteries are not supported
