What is the service life of rechargeable battery on cordless phone?
Under normal conditions, its service life is 2-3 year or longer. If any one of the following items occurs, the batteries should be replaced: 1) After each charge, the talk time becomes shorter; 2) Ring sign is not enough clear or talk effect is indistinct and chirp voice is louder. 3) The distance between cordless phone and the base should be closer and closer, i.e. the ranges that the phone can work become narrower.
