I had ordered the same 2 batteries. One was great, the other defective from the outset. The good I've been a friend and criticizes the other by the consignor. Yet in the same night you promised me replacement without Sending the defects. The replacement has taken a while, but then came twice. It has also been sought on its own contact and even gave me a headset as compensation. The batteries last even after months use nor very good.
