Precaution & Handling
1) Do not disassemble or short-circuit batteries.
2) Do not recharge batteries.
3) Do not dispose of batteries in fire.
4) Do not allow metal objects to contact the battery terminals.
5) Do not mix with used or other battery type (such as alkaline with carbon zinc).
6) Do not solder the batteries directly. If soldering or welding connection to the battery is required, consult our
engineer for proper methods.
7) Do not over-dis charge batteries. Force discharging batteries by external power source in a series may cause
explosion.
8) To install or remove batteries, follow the equipment manufacturer’s instructions.
9) Keep battery away from small children. If swallowed, consult a physician at once.
10) Remove batteries from device when it is not is us e.
Storage
1) Store in a cool, dry place before use.
2) Do not keep batteries at temperature of 45°C or above.
3) Do not keep batteries at relative humidity of 75% or above.
