Before you swap it

  • The code is printed on the flat face of the old cell. Match it exactly and the new one will fit.
  • Button cells with the same size can come in alkaline (LR) and silver oxide (SR). Silver oxide holds its voltage better, so an SR can stand in for an LR, but don't put an LR where the maker asks for SR.
