It's the battery that I needed to replace that an additional handset. I have a cordless phone Siemens Gigaset A 265 with 2 additional handsets for almost 10 years. My children are allowed to unload the one that was in their room and he would not recharge. With this new battery is nickel, no need to buy a handset especially that this model is no longer done. It would have taken me to take over a package. So I saved money and it works perfectly !!!
