About this item

  • 🏆ALL-IN-ONE PROFESSIONAL BATTERY DIAGNOSTICS - The FOXWELL BT780 is a professional all-in-one battery analyzer with a built-in power supply and integrated thermal printer, delivering complete battery status, starting and charging system diagnostics.

  • ✨CONSISTENT ACCURACY IN EXTREME CONDITIONS – Engineered for long-term reliability, the BT780 printable battery tester delivers stable, precise results from -20 °C to 60 °C.
