Review on 🔋 Tenergy TN299 Universal Battery Charger: Smart Charger for AA, AAA, C, D, 9V, 18650, and More with 4 Independent Charging Slots by Gin Bajema

So this is my second charger. The first charger I bought in 2010 is a Tenergy T9688 which I use at work and it works well. I needed one for my home and couldn't find the same one as before so I bought the TN299. The weird thing about these chargers is that if one charger tells you the battery is bad and doesn't try to charge it, the other charger will charge it. This happens in both cases, so I'm pretty sure I've thrown away good batteries in the past. So together they are 5 stars but individually they are 4 stars. So if you buy this charger it will tell you that some batteries are bad and you need a second charger which is not the same to know if the battery is really bad.
