Since about 3 weeks I have the third (!) New battery in use. 2 from the first provider I have wg. to lower service life (2 -. 2.5 days max, then de beam was without telefoniern away. The third battery I have from another vendor: The same problem, the service life is my old battery immediately. For me, now raises the suspicion that, because there is this guy so long, larger amounts of Altherstellung were delivered to the distributor. The original target capacity is no longer achieved due to superposition. The might notice that they should charge the battery "very long" is nonsensical, because bestowed independently of if it is loaded and that you can take it off. The big question: How can I get a good quality product? ?
