- I doubt it. I have a similar tester that is a different brand. These testers only test the battery voltage and the voltage of the alternator output. Mine works perfectly. I have had it for years and use it regularly in all of my cars and when helping friends diagnose problems with their cars. It comes in handy when I am using a power inverter to run light duty 120 volt AC appliances off of my car battery and I want to monitor the battery voltage so I can start the engine and recharge it before it gets too low. I can't speak to how the "start" function works, as mine does not have that function and I have never seen one that does. My guess is that it does that by measuring the battery voltage while you are trying to crank the engine and the red light comes on if the voltage falls below that point. The battery voltage of a good battery should stay above a certain point when the starter is engaged. If that function works well, I would say this device is well worth the extra five dollars or so that it costs above most similar devices I have seen. Most of the ones I've seen cost between $15 and $20 and can be found at auto parts stores. I wish mine had that function! It's a super cheap version of a load test. Be forewarned, though, that on some cars, the cigarette lighter and/or accessory socket are disengaged when the key is in the "start" mode. If that is the case with your car, the "start" function of the device won't work. the other tests should work fine, though, as long as the socket is getting power.by Richard029/15/2013Was this answer helpful?
