TOPDON Battery Tester
TOPDON OBD2 Scanner
[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.

Title: Unexpectedly good
Review: I have been using a 500 amp carbon pile load tester to test lead acid batteries for many years. It works well enough, but itâs 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. Iâve only owned it for a couple of weeks, so I canât speak to its longevity, but so far itâs 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 Iâm not sure how you could tell if I was 🙂

Title: Great tool for the money.
Review: This little gem is great. Itâs 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, itâs quick, accurate, easy to operate, and very portable. Hope this helps

Title: Very useful
Review: The app let’s you leave the device attached to constantly monitor your battery. The load testing feature seems accurate and helps to determine when batteries are too far gone to mess with. I use it on a bank of solar panel batteries at my remote cabin to monitor charging and voltage. The graphs tell you when the battery is charging during the day time and when it’s losing power at night. Good for charging boat batteries too..

Title: Simple basic tester
Review: Easy to use wo reference to manual. Does not agree with a better one I have. Shows lower values of battery life. But, a pretty good general reference for if your battery and charging system are working and how much life is left in the battery.

Title: No more battery mysteries
Review: 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.

Title: Great tool for any garage
Review: Yes, you can go to those parts shops and have them scan you battery but Iâve had to deal with tons of attitude and sales pressure in the past.So I stopped the inconvenience on its tracks and picked this up.It shows the same parameters those larger units show and you can diagnose your battery without leaving home.Very easy to use. Display is easy to see and understand.

Review: I needed a tester for my battery and this one works perfectly. Very easy to use. Once I determined the old battery was no good, I was able to use this on the new one to confirm it was at 100%.

Review: This tool helped me diagnose:2 failing batteries.One 40 percent health battery (time to replace too)It also tested my alternator diodes to make sure that the diodes in it are working fine.Although it does not detect a failing voltage regulator which is my main problem, it should be pretty obvious with voltage spikesOverall 10/10It also has marine cranking amps to pick from in the battery tester section CCA and anything else you might needI was gonna pick the bt200 but I don’t have any 24v systems or trucks etc so this works perfect and saves a few bucks picking the 12v option.
