This is a good tester if you want to quickly access the condition of a battery. The first 10 second use will burn off the dust/oil on the elements, then you're pretty much good to go. checked out 3 batteries in a minute with this. "Not for small motorcycle/four wheelers batteries" car, boat, rv batteries etc due to the 100 amp draw.

This tester seems to work OK based on the one battery I've checked so far. I was very nervous when I first did a load test and it smoked and smelled like burnt metal or something. It reminded me of an electric heater after being stored. I immediately thought this needs to go back. Thought about it a while and thought maybe it's just burning off it's newness so did it two more times and the smoke went a way so only time will tell if it is a durable and safe product.

the tester worked 1 time and then the next time I went to use it the load switch did not work, but the company I bought it from is sending me another. so maybe the next review will be good.
