Since months have already passed since the request from someone else and one of the main advantages of this series of Gigaset phones is precisely the possibility for any layman to replace the battery, I ask again, especially since it would also be the right battery for the Volla Privacy Phones.This would add to the 5-6 models you are actively selling here, which theoretically have no end of support thanks to free software and could be used as long as the hardware is still alive and well enough, as long as you can get batteries for it, ergo finally take them into stock! ;) Volla also sells the batteries that fit the phone -since the Volla Phone22 is "only" a rebranded Gigaset GS5 with a better OS-, maybe you can get them via them!
