Review on Batteries ANVOW Rechargeable Surface Battery by Melanee Deal

After receiving these batteries I want to charge them but two of them will not charge. I use a suitable charger (Nitecore Intellicharger i4). First, three sets of indicators flashed that charging was in progress. I connected the battery to a different dock connector on the charger, it still wouldn't charge. Then I started hearing some sort of hiss and realized that one of the other batteries was being charged. I took it off the charger and put it to my ear and it hissed and gurgled. When I put it back in the charger it stopped charging. It doesn't hiss anymore either. Now I have 2 batteries that are not charging. I will not buy these batteries again.
