Operating Temp: -30C to 60C Self Discharge: ~1% / year Industry Standard Dimensions mm (inches) 3.20 (0.126) 20.00 (0.787) 17.70 (0.697) Maximum 19.70 (0.776) Safety: (1) KEEP OUT OF REACH OF CHILDREN. Swallowing may lead to serious injury or death in as little as 2 hours due to chemical burns and potential perforation of the esophagus. Immediately see doctor; have doctor phone (800) 498-8666. 0.20 (0.008) Maximum Ref. Permissible deflection from a flat. 0.10 (0.004) Minimum Ref. (Applies to top edge of gasket or edge of crimp, whichever is higher.) (2) Battery compartment design. To prevent children from removing batteries, battery compartments should be designed with one of the following methods: a) a tool such as screwdriver or coin is required to open battery compartment or b) the battery compartment door/cover requires the application of a minimum of two independent and simultaneous movements of the securing mechanism to open by hand. Screws should remain captive with the battery door or cover.
