the original battery of my ancient Gigaset AS140 has maintained a proud 10 years. Only the talks were getting shorter, then went nothing more. The New was within two days because he fits into the phone, can be loaded and holds an eternity, or I am now too used the old ;-) Only the mini plug I had zwängeln something pure, but that's probably like that. The main thing it fits. I will not complain about the price (3.84 including delivery) also. I'm back online!
