In general, charging is normal, if you look at it only in charging, there are many minuses in everything else. The screen does not always show the correct battery percentage. Each time it shows differently, if you pull out and reinsert the battery, it will be a completely different number. Also, 2A charging is used only on one socket when charging only one battery. When charging two batteries, only 1A is used, while when charging three or four batteries, only 0.5A each is used. I would advise you to look at other chargers, for the money you can find better ones.
