Batteries are different from the picture. No printed markings or labels on them, traces of corrosion are on the bottom plate, and dirt particles left belhind the blue foil. When charging, 3 of them was heating up during the process, up to 35-40 degree. Only one of them remained cool, as expected. Charging current was 1.6A DC (not pulsed) only. Also the self-discharge rates are too high: voltages are decreasing day-by-day, by approx. 10mV in every two to three days. Seller refused to replace them, dispute was initiated. The judgement that passed,was sending them back an receive refund. This is not realistic, however. Return cost would be more than the value of the goods itself ($22.43), so that would just increase the losses. Unfair decision, and no way to protest against it.
