AUTTGINN 6/8/12/16/24V Battery Load Tester Automotive Car Battery Tester,Battery Charging System Tester and Voltmeter Tester with LCD Display for Cars,Golf,Motorcycles

Guessing whether a battery needs replacement or if the charging system is the real problem wastes time and money, and this AUTTGINN load tester removes that guesswork with an actual load test rather than just a voltage reading. The difference matters because a battery can show good resting voltage and still fail under load, which is exactly the condition that leaves you stranded. The voltage range covering 6, 8, 12, 16, and 24 volts makes it useful across cars, motorcycles, golf carts, and other equipment without needing a separate tester for each application. The LCD display reads clearly in a garage or outdoor setting without squinting at a needle gauge, and the charging system test function lets you check alternator output alongside battery health in the same session. Build quality feels solid enough for regular shop use without the clamps or connections feeling flimsy under the current draw of a proper load test. For DIY mechanics and anyone who wants to diagnose battery and charging issues accurately before spending money on parts that may not solve the problem, this tester pays for itself the first time it identifies the actual fault.

Very good tool

Lori Chase's review is spot on. It's simple. It works. My Club Car utility cart died. I took a battery to local car parts shop, "bad cell" was the diagnosis. Is it me? Has Covid made me cynical? Or are people truly just dishonest by choice these days - are they taught to lie, cheat, and steal, or what? Wanting confirmation of the pricey diagnosis, I got this tester for 1/6th the price of one battery - I have 6 8v batteries, looking at $1200-$1500 to do it myself, plus a sprained back wrestling the beasts in and out of the cart. Tested battery with reported "dead cell" - 8.3v / 7.1v under load. (Don't hold the load switch too long - first go it started smoking! - a simple resistor to simulate load.) Seems reasonable behavior to me. Same for batteries #2-5, within .1 volt. But battery #6 was 7.1/nothing - a bad cell or two, eh? I give them only 4 stars because I just wish the Chinese manufacturers would not practice the English they've learned in some 6-week intensive when they write manuals. There is nice, comprehensive set of instructions on decal on the back of the tester. (See pic) But if someone could translate the words there into meaningful English for me, I would really, really appreciate it. It's really funny to read. Maybe I should give them an extra star for that. This device is simple and cheaply built, but I expect it to serve me well for a long time, given it's going to mostly gather dust in my garage between power crises. Actually, my electric-start generator battery was behaving "mostly dead" too. So I checked it. Yup. 12v battery registered 10.1/nothing. So a two-fer! I note one reviewer gave them 3 stars and complained that the instructions were not sufficient for him. Well, here's the essence: Clip the black lead to the negative post ("NEG -") of the battery, and the red lead to the positive ("POS +"). The digital display will show the at-rest voltage of the battery. For a 12v battery this should be between 12.0 and 12.5v. There is a toggle switch on the bottom of the tester. It is spring-loaded. Switch it to one side or the other - for less than 5 seconds. While it's on, you will get a "load" voltage for the battery. This should be around 10v for a 12v car battery. Lower values - replace the battery - after checking battery water levels if they're accessible. The instructions, just in case you're interested. Pay particular attention to item "Four, warning." I might note in all seriousness that these instructions were obviously written for a device with an analog meter readout (green-yellow-red zones, pointer, etc). This model is a red digital face, like a 1978 clock radio. The pics on its Amazon page are accurate A, battery testing Test battery capacity status, can effectively judge the battery discharge. Second, the testing scope Battery rated voltage is 6v, 12 v, 24v capacity of 32-500 ampere hour dischargecurrent is 100-120. Three, test methods Clip clip on the storage battery pile, indicator for the anode, can undertake test regardless of is the cathode, press load switch until the pointer is stable and time shall not exceed 5 seconds. Four, warning, It is forbidden to fire don't let fall to the battery of the metal, to prevent to produce an explosion caused by spark. Test the single, the red clip must be sandwiched between the anode and the test stick inserted into the table inside the bottom hole for the single test.

Works perfectly and helped detect one bat battery in my Golf Cart

This tester worked as it is supposed to. Found a bad battery on my golf cart with four 12v batteries quickly. First 3 tested at resting voltage around 12.5 volts and load tested at 10.8 volts. Last battery tested at resting voltage 10.2 volts; hit the load test and voltage disappeared altogether. Golf cart shop would have told me I need batteries and a $400 endoplasmic reticulator or something to that effect.

I ordered this to check the voltage on my golf cart batteries which, saved me the trouble of removing the batteries and carrying to the part store to test!! I was greatly surprised to see a good quality tester for such a low price!! I highly recommend it!

You can't vary the load so you don't really know how bad the battery is. The load switch did nothing. The instructions are completely incomprehensible (picture). This is only the second item that I have returned out of several hundred and only my first review. POS

Not sure if it was from shipping or what but it was beat up pretty bad and even had a screw missing when it arrived. I was pleased that it did work like it was suppose to. I took off 2 stars for the box and screw.

Dieses kleine Gerät ist eine gute Investition, denn es hilft wenn die Autobatterie keinen Startstrom liefert. Damit konnte ich schon jemanden helfen, dass Auto wieder zu starten ohne das Risiko einzugehen, mit der eigenen Autobatterie zu überbrücken,was durchaus das eine oder andere Relais beschädigen könnte.

Buenas pinzas. Hace falta manual de uso.
