Been using this charger for about 1.5 years. Everything has been fine until recently when I went ahead and put my batteries in the slots and the LCD screen didn't come on(it should). I unplugged the charger and took my batteries out and tried to the process all over again on another outlet and the same thing happened. So I decided to test it out a bit and put it in the middle of my garage. I was needing to do stuff outside anyways so I grabbed a fire extinguisher and waited. Gave it 2 hours. I noticed the charger itself was hot and the batteries did not charge. tldr; d4 charger lcd not working and not charging batteries I don't think my warranty works anymore too which sucks. Any ideas?
