I actually use this thing alot. Tells you all about your battery and works good. Easy to use. Wish I had bought one years ago.

Cumple bien su funcion

I purchased this to test my 6-volt deep cycle batteries used on my RV. As things sometimes work out the day I received my tester my cars battery light came on. I have never seen this light up when driving and seeing how I replaced the alternator about a year ago I felt it might have been the battery going bad. I opened the hood to inspect the battery which is now 3 year and 2 months old. (2 months past the free replacement warranty period). I was about to pull out the battery and go purchase a new one when I remembered I had just purchased this fancy battery tester. I hooked up the tester which powers on as soon as it is connected to the battery. The first thing I see is the battery voltage which was reading low. (Now worried about the alternator not charging the battery) I ran the battery test. The menu is easy to follow, and the tester had me perform actions like turn on my headlights then turn them off so it could measure the drop in voltage. Anyways good news was the battery was fine as identified by the test tool. I cleaned the post and reconnected and started the car and now the light on the dash was off and after driving around for about 30-45 minutes (maybe longer) I retested and the voltage had climbed back up and the tester was no longer telling me the battery needed to be charged. I also tested my 2 6-volt batteries. both are reading a low charge and they need to be replaced. I'm running a full charge on them now to make sure they are floated then will retest. If the test tool continues to tell me they need to be replaced I will take them back into Batteries Plus to have them test. The reason for this is my Inverter will not power up and throws a low voltage alarm which has me thinking one of the two new 6 volt batteries are bad. The test tool is telling me they both are bad so will continue my testing and will hopefully update this review with my findings. At this point I'm very happy with this tester, it is easy to use and seems durable.

This tester is so easy to use. It's as easy as plug and play. I checked various batteries on the cars and off the car. All diagnosis was as I expected but confirmation was good as I didn't have to go to a garage or elsewhere which always saves you money. It is so easy to use, step by step on screen, I don't know why I didn't buy one sooner.

Great product does the job it says and works better then drop tester thanks
