Key features

• •Upgraded from the Original BT705 – The BT705 Plus is the enhanced, next-generation upgrade to the classic BT705—now delivering results up to 30% faster with a more powerful processor and refined algorithms. It provides higher accuracy even on low-voltage or nearly dead batteries, making it easier to spot weak batteries, alternator issues, and starting problems before they turn into breakdowns or towing bills.
• •Reliable Results Even in Freezing Winter Conditions – As winter approaches, cold weather can quickly drain or damage batteries, but the BT705 Plus is built to handle even the harshest conditions. Featuring high-conductivity clamps, this tool delivers accurate readings even in freezing temperatures—helping you spot weak batteries and prevent cold-start failures before they happen. Stay ahead of winter breakdowns and keep your vehicle or equipment running smoothly all year long.
• •Complete Battery, Cranking & Charging Tests in One Tool – No need for multiple tools, the BT705 Plus performs battery, cranking, and charging tests in any sequence and measures key metrics like SOH, SOC, cranking voltage/time/CCA, and charging ripple. Detect weak batteries, cold-start risks, or alternator problems with ease—helping you identify potential failures before they disrupt your day.
• •Easy to Use with Clear, Colorful Readouts – A high-contrast color LCD ensures crisp visibility indoors or outdoors. Five diagnostic indicators are displayed at a glance, making testing easy for anyone. The extra-long 5.9 ft cables let you test batteries solo—no extra help needed.
• •Wide Compatibility for 24V/12V Vehicles & Eco-Friendly Choice – Compatible with Flooded, AGM, Spiral, and GEL batteries (not for lithium), covering 12V/24V systems for cars, trucks, RVs, boats, heavy-duty, and tractors. Ideal for mechanics, fleets, and DIYers. Certified under GRS standards, FOXWELL delivers both performance and responsibility. Keep your batteries healthy, reduce waste, and drive smarter all year round.
• •Note: (1) You need to enter the rated CCA value of the battery according to its labeling; (2) For in-vehicle testing: ensure all accessory loads are switched off, the ignition key is in the OFF position, and all vehicle doors are closed
