Excellent service but 1 battery would not charge unfortunetly otherwise excellent products

I charged and discharged a single battery at 1 amp and got 1458mAh from it. The spec says 1200mAh in some places and 1700 on the battery. I guess if I had discharged at less than 1 amp I could have got closer to the recommended capacity. They charge in about 2 hours. When discharged they stay at almost 1.5v for the entire time and then drop to 0v. Not good for critical applications as no warning is given as they near the end of their discharge.

Great for what I wanted

Like that they don't need a separate charger.

Not charging. It’s a waste product. I lost money

Generally the batteries work well and it's good for led string lights which they where bought for. However two problems first, capacity was lower than advertised. But second one a bit more worrying. The charge cable is a 4 to 1 usb-microb to usb A. On my cable I later discovered one is wired backwards... I noticed that it made my wall plug usb port very hot a couple of times and one battery didn't charge. I tried using my smart usb pack and it detected an undervoltage error as the +/- where reversed. Luckily there wasn't a fire. No obvious way to contact seller or return so not too happy.
