CR2450 DatasheetEEMB Li-MnO2 Battery (Edition: Apr. 2016) Discharge through Conductive Electrostatic Prevention Mats Conductive mats are widely used to prevent static electricity from destroying semiconductors. If a circuit board with a battery mounted in put on a conductive mat, the soldered conductors may touch the mat, providing a discharge path for the battery. Improper Battery Mounting Polarity When the battery's positive (+) and negative (-) terminals are backward with respect to the battery mounting's polarity marks, the battery may be discharged, depending on the type of electriccircuit. Solder When the battery's lead plates are dipped in a molten solder bath, the battery is temporarily short-circuited. Therefore, complete dipping within 5 seconds.
