I have no idea how old the landlines in our house are - I can tell you I remember talking about them being necessary to keep the house light found if a nanny ever showed up had to call 911 and our kids are 18 and 25 now so it's been a while. Telephones became increasingly unusable and no longer held a charge. The manufacturer no longer offers the batteries needed (they have a newer model) so I ordered these as they turned out to be correct. you absolutely! The landline phones are working normally again, although they are now out of service so that elderly relatives can be located if they ever need to call for help from here.
