Review: pleasure to have - I have use this now three times for myself and once for the neighbor and has worked perfect and it saves you a trip to the parts store in town. I do like this product it is easy to use, easy to read great tool to have if you have anything battery you need one of these !
Review: Good brand, good product! - Purchased this Top Don battery tester after seeing a couple YouTube videos recommending it as the battery in my suburban was not holding a charge. Tested the battery and it indicated to replace. Tried the Noco battery conditioner but did not resurrect the battery and got a new battery. Yes, I could have driven to the parts store and have them test it, but it is much easier, faster and more convenient to do it yourself and this item let's you do that. To me, we'll worth the price for the convenience of testing at home. That way i can research where I want to get the battery and not feel like I have to get it from the store that tested it for me. Works as it should, nice addition to the tool box.

### ⭐⭐⭐⭐⭐ Unexpectedly good
*by M***S 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 :)
