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!!! Review: Properly functioning - This battery, starting, a d charging system tester is excellent. I purchased it to .ake my life easier when doing an inspection that requires this information. It comes in a nice hard carrying case. I open the case, attach the sufficiently sized alligator clips to the tester body, then attach the clips the the battery being tested. I can test only a battery outsideof a vehicle if I want to. Or I can test the battery in a vehicle, then proceed to start the vehicle in order to test the starter cranking voltage, then once running I can finish by testing the alternator and charging system. Once the tests are complete and the program has run, I can print out a receipt that states whether the battery and subsequent tests have passed or failed. It is all very intuitive and easy to use. Similar to an alignment machine it really walks you through the steps. So, this battery, starting, and charging system tester, is a winner in my book. ## Features - FLAGSHIP 6V/12V/24V BATTERY & SYSTEM DIAGNOSTICS - Upgraded from FOXWELL BT705, the BT780 is a flagship battery analyzer for technicians, dealerships, fleets, battery retailers, service professionals and DIYers who need fast, dependable answers.

So, the reports I printed for my customer look very odd (it shows I did the test last year). The case is not good. Cables don’t fit well in the case. Case supposedly has a cut, so you don’t have to screw and unscrew the cable jack every time that you are using the machine... but the cut is offset,... and it can’t be used to store the machine with the cables on. Screw and unscrew the cable jack is a bit of a pain in the b. Plug is inside of a deep or orifice and the fingers don’t really fit on this small spot. Test is ok. Menu is easy... in exception of date and time options. I tried to clean the printer but it always does a line on the report, which is a bit odd on a brand new device. ## Frequently Bought Together - FOXWELL Car Battery Load Tester for 6V 12V 24V Cranking and Charging Start-Stop System Test Tool BT780 Auto Batteries Analyzer with Built-in Thermal Printer&Carrying Case … - FOXWELL BT705 Car Battery Tester, 12V 24V Battery Tester 100-2000CCA Battery/Cranking/Charging Tests for Cars Motorcycles SUVs Trucks, ideal battery tester for Professionals with 2.8 inch LCD Display - JOREST 168 Pcs Car Fuse Assorted Kit, 114 Mini Blade + 54 Standard+ 1Pullers – 11 Specifications Mixed Auto Fuse: 2Amp 3A 5A 7.5A 10A 15A 20A 25A 30A 35A 40A --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/157172951-24v-12v-6v-battery-tester-with-printer-foxwell-bt780-car](https://www.desertcart.hr/products/157172951-24v-12v-6v-battery-tester-with-printer-foxwell-bt780-car) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-23*
