I still use a Siemens S55 as a second phone in my hands-free in the car. The old battery had apparently given up the ghost and I ordered this battery as a replacement. To make it short: No one whit better than the old one! The mobile phone is switched off in the charging cradle continuously from. Calls impossible. The same behavior was also evident with the domestic charger (original Siemens). I have the battery then tried in an old Siemens C55 (to rule out that the mobile phone is defective with the same behavior!). So with different chargers and various mobile phones each of the same error. No idea if it seems to me as if Old batteries sold as new. Hands off!!
