CR2450 ‐ 650231 Instructions for Usage and Safety The battery consists of lithium, organic, solvent, and other combustible materials. Proper handling of the battery is of utmost importance; otherwise, the battery could lead to distortion, leakage (accidental seepage of liquid), overheating, explosion, or fire and cause bodily injury or damage to equipment. Please strictly comply with the following instructions to avoid the occurrence of accident.
CR2450 ‐ 650231 battery should not be soldered directly to equipment which it must be done only on tabs or leads. The temperature of soldering iron must not be over 50 degree C and the soldering time must not be more than 5 seconds; it is important to keep the temperature low and the time short. The soldering bath should not be used as the board with battery could stop on the bath or the battery could drop into the bath.
CR2450 ‐ 650231 Using and setting protective resistance In order to refrain from changing the battery by large surges of current when the diode is failed, the protective resistance should be applied. It is recommended to adjust the protective resistance to make the maximum current not over the figures as stated in the table.
