Features

  • [Car Battery Tester] You can easily test and inspect your 12V lead-acid battery with this TOPDON car battery tester. The SOH (State of Health), SOC (State of Charge), Voltage, Current, Rating, and numerous other understandable analytical data are provided by this battery tester. It is compatible with 100-2000CCA regular flooded, AGM flat plate/spiral, EFB, and GEL for their optimum performance.
  • [Wide Application] This 12V battery load tester can only be powered on once it is properly attached thanks to a safe passive testing approach. You may test the batteries of a number of vehicles, including cars, motorbikes, trucks, RVs, ATVs, SUVs, boats, yachts, lawnmowers, and even golf carts, without needing to charge the device first.
  • [3 Testing Function] A battery health test will determine whether or not the battery is in excellent operating order. A cranking test will determine whether or not the electrical system has sufficient power to start the engine. Check to see that the charging current, rectifier diode, and generator are all functioning normally. This handy auto battery analyzer makes sure your summer road trips wont end on a flat.
  • [Ergonomic Features] To help you rapidly determine the health of the battery, this load battery tester is built with three different colors of LEDs. It's easy to use because it operates through a menu system. Additionally, for a reliable and secure connection during the testing process, premium-quality copper clamps have polarity reverse prevention and spark proof features.
  • [Great Choice] The TOPDON BT100 is small and compact, making it simple to keep in a glove box or center console. This battery load tester's rapid and precise results will enable you to decide whether your car battery needs to be replaced or jump-started making it an excellent choice for auto shops, garages, and DIY users who frequently check batteries.

I use this every single day and it seems to be pretty accurate. The functionality of the battery tester is easy to use and can test the charging system as well as doing a cranking test. Would recommend anyone needing a better tester for 12v battery’s

  • Fast, Accurate, and Easy to Use
This tester gives clear, detailed readings on battery health, charge, and cranking performance. It’s plug-and-play with no setup required, and works on a wide range of vehicles. I’ve used it on cars, motorcycles, and bus with no issues. It’s compact, reliable, and a must-have for any garage.

  • Easy to use - better than plain multi meter
Easy to use. Just attach leads and scroll through the prompts. Much better than using multi meter. I use this to monitor battery health on a auto start/stop featured Hyundai. Good investment I think.

  • solid build quality
This battery tester is pretty cool. It is well made. It does various tests, testing CCA and a few other options to test capacity. It does all the different battery types. It has functions for testing battery charging and discharge as well. The buttons are intuitive and operation is straight forward. The display is good and easy to read. The wire length is decent at around 32 inches to the alligator clamps. I tested it with AGM and standard flooded batteries. ... show more
