If you are looking for a professional battery load tester suitable for both 12V and 24V systems, the Foxwell BT705 and BT780 are two excellent options. These tools can perform cranking tests and charging system analysis, making them ideal for various types of vehicles and equipment, including passenger cars, trucks, SUVs, heavy-duty machinery, boats, yachts, lawn mowers, and more.
These digital battery testers also function as reliable battery testers with load, capable of handling all batteries rated from 100 to 2000 CCA. They support a wide range of battery types, including: Regular flooded batteries, AGM flat plate, AGM spiral, GEL batteries, EFB, Start-stop AGM batteries.
2. Which Foxwell Battery Testers Support Charging System Diagnostics and Cranking Test?
Foxwell BT705 and BT780 both support full charging system diagnostics. These tools can easily perform three key tests: battery health, cranking, and charging.
By analyzing battery voltage, internal resistance, SOC (State of Charge), and SOH (State of Health), they provide a comprehensive view of the battery's overall condition. For the starting system, they can assess the cranking state and cranking voltage, helping determine whether any issues exist with the starter mechanism. Regarding the charging system, they can analyze alternator output and provide detailed charging data.
As a professional battery and charging system tester, both BT705 and BT780 are excellent choices.
In comparison, the compact Foxwell BT100 Pro can read real-time battery voltage but does not support advanced charging system diagnostics, making it more suitable for basic 12V home-use scenarios.
These models are ideal for users looking for a reliable Foxwell battery tester or a precise battery charging system tester for vehicles of various types.
3. What Are the Advantages of the Foxwell BT780 Compared to the BT705?
The Foxwell BT780 offers a more efficient workflow compared to the BT705. Specifically, it includes the following enhancements:
