I ordered at 20:08:13 2 Duracell batteries 3.0V type electronic 2450 - Lithium button cell (CR 2450) and the delivery was also timely. The cells were empty but what I also complained immediately to the suppliers / producers and called for an immediate replacement delivery. The provider, however, rejects any liability by sending two new cells from beneath the flimsy grounds that my unit was probably broken or the use of cells was carried out improperly. This is called nowadays "service" and "customer service" - I think that's an insult.
