  • [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.

  • So simple yet very useful
Wow, this battery tester is great. I really like the effectiveness of this little hand held device. I should have bought one a long time ago.

  • Works perfectly.
This is a great affordable tester. I watched a YouTube video that featured this tester. I tried it the next day after it arrived on both my cars and it worked flawlessly. The menu on the tester is very clear to use and the data that displayed was useful to me. Read the supplied manual while trying it out and you will be up to speed in about 10 minutes. ... show more

  • Very useful tool AAA
I bought this a few weeks ago to test my boat batteries. Tested both the charging and the status. Very easy to use and navigate the menu. Today I used it to test a Mercedes Aux battery. See attached Pic. It confirmed my guess of a bad battery. I've used this numerous times and am impressed how easy it is to confirm good or bad or maybe a bad charging system. ... show more

  • Function is great
Not the most well made piece of equipment. Gets the job done and nice to have as a hand held unit. Terminal clips are cheap and small. Overall glad I got it.

  • Great tool for the money.
This little gem is great. It’s worth every penny I paid for it. I was told by a good friend, this was the way to go. I have now used it numerous times, it’s quick, accurate, easy to operate, and very portable. Hope this helps

  • No more battery mysteries
This unit was highly recommended in several You Tube videos. The BT100 clearly says what it does in the manual and does what it offers when connected to the battery. For once you don't need to charge something since the unit gains its power when connected to the battery source. The battery in my car charged up fine, but there was a lingering question as to whether the battery was in need of replacement. I could not exactly remember when I changed the battery in the specific car. The BT 100 answered my questions. The charge was 100% and it listed the battery in good condition. I did not try the other functions as yet, but the videos showed the range of capability of the unit. The cost is reasonable, and of all the car stuff that I have, I did not have anything that tested the condition of the battery. A good unit to have on hand. ... show more

  • Nice tester and easy to use
I originally bought the Topdon AB101 model and it worked intermittently. I found the battery clamps very finicky and difficult to get positioned correctly to get any results. Often the unit would just show "testing" and never give any results. Topdon did right by me and I ended up getting the BT100 tester. First off, the clamps are far superior and make much better contact with the battery terminals. The test results come up fast and I like the cranking test and the charging test features as well. For a pure digital battery tester, this BT100 is the way to go. I can easily recommend this particular model. UPDATE 5/20/24: This manufacture has continued to respond and make me happy with my purchase. It is rare today to find companies that not only stand behind their products but do right by their customers who buy their products. I have to say, I am very impressed. ... show more
