About this item

[Car Battery Tester] You can easily test and inspect your 12V lead-acid battery with this TT 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 won’t 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.

5.0 out of 5 stars Nice tester and easy to use
Reviewed in the United States on May 16, 2024
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.

This is a great product for testing both your car battery and the charging system. Instructions are clear and it does do a great job of revealing issues with a battery as well as the charging system. Cranking amps and voltage are all displayed clearly and it even tests charging by asking you to rev the engine after starting. Very useful product.

5.0 out of 5 stars Work great to test out Semi Truck batteries

This tester works great. I tested it against an expensive tester that a coworker has and it gave the same results but I didn’t pay tool truck pricing for mine. I use it on medium to heavy duty batteries found in f750s and Semis like Freighliners. Definitely worth it.

It's exactly as advertize. Simple and convenient to use. Works using the car battery alone. No need to ever replace any in the tester itself.

5.0 out of 5 stars Unexpectedly good
Reviewed in the United States on April 28, 2023
I have been using a 500 amp carbon pile load tester to test lead acid batteries for many years. It works well enough, but it’s large, heavy, and tends to smell bad as it heats up when you use it. It also drains a significant amount of energy from the battery under test to the point where the user manual suggested to charge the battery after running a load, test. Also, the analog voltmeter, is not particularly accurate or easy to read in dim light or at an angle, due to parallax.

I bought the TOPDON BT100 with low expectations, but I was proven wrong. The battery health (load) test works by putting a high load on the battery for a very short time, so it does not dissipate much power during the test. This has the advantage of allowing the device to draw very little total energy from the battery and thus generate very little heat. There is also no need to recharge the battery after the test. While the load is applied it measures the battery voltage and calculates the internal resistance of the battery and its capabilities for cranking amps (CA and CCA), as well as displaying its loaded and unloaded voltage. You can set the specified CCA of the battery before the test, which allows it to return a go / no-go result. One of the many advantages of this approach is that the tester is able to determine if the battery clips are not well connected before the test. I tested the BT100 on a number of lead acid batteries, including a 9AH UPS battery, an 18AH UPS battery, a 250AH AGM battery bank that I use for power back up, and my car battery which is rated for 520 CCA. In all cases, I got nearly identical results to the carbon pile tester.

In addition to battery health, you can use it while starting the car to measure cranking time and the minimum battery voltage during cranking. You can also use it to test the charging system in your car, and of course, to report the battery idle voltage.

Overall, I was pleasantly surprised at the quality results provided by this device. I’ve only owned it for a couple of weeks, so I can’t speak to its longevity, but so far it’s a huge win.

Disclaimer: I purchased this with my own money. I was not asked to write this review, and these are my own opinions. Also, I am not an AI bot although I’m not sure how you could tell if I was :)
