Bought this charger in dec of 2018. I used it 2 times and it worked great. The third time I went to use it it would not read the voltage of any batterys. I may have done something. I dint belive so. I have been in and around the electrical field most of my life. But because it is out of a 90 day warranty period. I'm stuck with a 200 dollar charger after about 4 and half Months that is broke. I'd look else where. Maybe a comoany that stands behind there priduct sales a but longer and better. Update. To be fair. When I decide not to give up on getting a replacement.. I called the company back again. I Got a different Rep. The issue was resolved with a replacement. So all in all. I would recommend the charger.
