OTC 3180 100 Amp Battery Load Tester - 6V and 12V Compatible

Works great

Seems to work as it should, only used it twice since so far I received it.

I have used this type of battery tester for years, mine disappeared some time ago, so this was a replacement for it. I got so tired of taking batteries to the parts house/store to have them check them for me. I have looked to buy another for some time but at the parts house/store they are way to expencive. I decided to take a look on Amazon and as soon as i found this one I bought it due to it is OTC brand, a brand that I trust and exactualy like the one that I used to have and that is was half the cost shipped then at any local store, including Harbor Freight, which by the way told me (local store) they do not carry them even though they show them on there website... If you are looking to own a battery tester that will last dang near forever, but this one. I used one just like this one for years in an auto repair business.... Buy it and never look back, well unless zombies are chasing you.

Easy to use, Heavy duty, chrome plated, ventilated case. Determines state of charge, cranking and charging volts. I did like the thick gage wires with strong alligator clips. Works well on both 6 and 12v batteries. I decided to go with the metal load switch verses plastic switch on other units breaking. Works as expected. IMPORTANT!! LOAD SWITCH TEST TIME 5-10 SECONDS MAX! BEWARE THE ELEMENTS BEHIND THE VENTILATED STEEL CASE GET VERY HOT TO THE TOUCH.

If you quickly want to know if a battery is good or not, this is a great tool to have in your inventory, and not expensive. It's not super-accurate, but when you're looking for a simple "Yes or No,", it's fine. ProTip: DO NOT LEAVE IT ON FOR MORE THAN THE RECOMMENDED TIME PRINTED ON THE DEVICE. I think it's 15-seconds but even that is a long time. You're essentially holding a really hot toaster. A quick on-read the display-off will suffice.

I've seen these around for years and when a shop would check my car battery, they would use one almost exactly like this model. I figured, if it was good enough to be used by a repair shop, it would be good enough for me. Worked flawlessly and as advertised. Clamped the leads to the battery posts, flicked the switch and it indicated that the battery had to be replaced on my sump pump battery backup system. Saved me a lot of time not having to check the Wayne backup system components. Now I have to get another battery and I'm good to go. It's a tool that you may rarely use, but if you have one, it pays for itself in allowing you to diagnose your battery and charging system without going to a shop or risking getting stuck in the middle of nowhere with a dead battery. Just be careful, follow instructions and always wear safety goggles when working around any lead/acid batteries.

This does the same tesing that most mechanics will do to check the condition of your battery under a load and can see how well the alternator is charging. Smart tool for most DIY mechanics. I can check family and friends cars and save them time and money letting them know where the problem is when trying to diagnose if it's the battery or alternator. Good quality at good price.

Generator would not start, battery voltage was good, could only tell battery was internally open by using high current draw. received quickly, works as described, simple concept, not much to go wrong, should work for many years,

El producto esta bien pruebas de bateria sin problemas solo que el cable y pinzas se ven muy fragil los cables muy cortos . Ecomprado otro modelos de esta misma marca y si me antraido cables y pinzas uso rudo alo mejor no es original

This tester is well built. It is accurate and does exactly what it is supposed to do. Cables are short but so are most load testers. She warms up good as they do but the coil handles it well. Would recommend. GOOD VALUE HERE
