These battery holders are designed for sure and easy load-
ing/ removal of Panasonic coin type lithium batteries in / from
equipment enabling the batteries to fully exploit their capabili-
ties as the backup power supply in C-MOS RAM memory and
microcomputer memory. All of the battery holders are de-
signed to prevent inverted insertion of the battery.
