Review: The FOXWELL BT780 Car Battery Tester is so excellent for the price of $259.99. Full of the most frequently needed/desired features and it's way easy to use. Just hook its gator clips to the vehicle battery black to black, red to red and this unit gives you instructions on its screen step by step to do battery or full system tests. It's fast and it's very accurate! This unit performs like something costing $1000+ from other manufactures...and with its own 9-volt battery installed this unit a little more accurate and capable as its operation does not rely entirely on power from the car battery that it’s supposed to be testing.... The cable connector to the unit has a very tight space around it...it’s hard to fasten down the screw cap on the connector because it’s hard to get your fingertips onto it to tighten it in that small space. Also, the first time I printed the data slip it was not legible...I don't know why it did that but I did another print out days later and it came out just fine... If you need a GOOD vehicle battery/system tester this unit will do above and beyond for you, especially at this really nice price for all it does. Need one? BUY IT!!! ## Features - UPGRADE TO TRUE PRO TESTING - Step up from the trusted FOXWELL BT705 car battery tester to the BT780 with 6V SOH/SOC testing, 12V/24V cranking & charging diagnostics, a built-in printer & custom shop/technician names.

In the quick tour guide it says to hold the left, down and menu buttons simultaneously. This has no effect.
