Query: Poor quality, 2 dead cells, one exploded on first use

The charger is mediocre, it only charges PAIRS of batteries, not singles and has no indication of charge complete.But the batteries are a waste of money... potentially a risk to your equipment.Two of my 4 NiMH rechargeable cells would not hold a charge - zero volts, right out of the box. One of the "free" alkaline cells literally exploded in a radio, blowing the back of it after 1 hour of moderate (300 mA) rate use, filling the battery case with caustic goo.I noticed that unlike quality NiMH cells, these "Tech B" cells have no (visible) overpressure vents to prevent their explosion on charging either.
