What does this mean on top of the battery: Top Charge Date 4/18/11.
Also, I live in a 2 family house. My landlord has FIOS for years and never had to replace the battery. Me on the other hand have FIOS for a year and half and have problems with the battery. Is there a way to tell if she switched batteries? Would the battery say its from Verizon because mine didnt say that.
