Review: Great Indicator! - Note: This is NOT a carbon pile tester of old but a great tool to perform a quick check. And it is also much lighter, convenient and more compact than Ol Smokey. I found this works best when directly connected to the battery vs the "access nipples" under the hood on my 2024 Audi A5 when testing for load. My battery in is in the trunk under the spare tire. When tested from the access points, the battery tested low but when directly connected, showed up a more believable 55% on the OEM battery. (Note I live in Florida and the heat takes a toll, so I have "learned" to test periodically.) On my bride's Ford Escape, you have to hold your tongue right to get good connections as the battery is under the cowl and I didn't feel like removing the hold downs to pry it out to get a better hands free connection but on that car, it showed a 80% on a 2 yr old Interstate ostensibly made for the hot climate. The other test functions are viable with the most interesting to me the ac ripple test (anyone who owned a 7th gen maxima can appreciate that early warning as those OEM alternators failed regularly every 100,000 to 150,000 miles with High Ripple (don't know if that issue still exists with their diode packs of today but it ran very hot under the hood and those diodes were NOT mil-spec!! :) ) I also appreciated the "dumb guy" indicators when you didn't ensure a good connection. Really helped with those "DOH!" moments. The voltage reading was spot on when compared to my fluke and old Simpson 260b. Nice Job.
Review: Easy, Reliable 3-in-1 Battery Tester - I just installed a brand new car battery and checked it with the TOPDON BT100. It showed the battery was bad, which probably saved me from being stranded. The battery was under warranty, so I got a new replacement. The tester is very easy to use and gives clear results. I especially like that it’s a true 3 in 1 tool: it tests battery health, checks the engine crank, and measures the charging system. Now I can conveniently check my battery anytime without going to AutoZone or O’Reilly Auto Parts. This is a great value and definitely worth keeping in the car.
