I put 3 batteries in the DECT telephone immediately upon receipt. This made no muchs. Therefore, I have put all 4 batteries in my LCD charger. If was "BAD" appears and refuses to load. Voltage measurement revealed: 0.00 volts. So best right after your purchase by all battery test ... I hope now Amazon shows customer friendly. Addendum: Amazon has refunded the purchase price upon return as expected. PS: I am now, however, almost completely switched to Eneloop batteries. Since they are IMHO better and cheaper.
