注意事项 PRECAUTIONS
1
Charging safety: Avoid high current/voltage charging; use recommended 3.1V voltage and 0.2mA current to prevent swelling, fire, or bursting
2
Handling precautions: Do not heat, disassemble, or dispose of in fire; do not solder/weld directly to the battery (risk of overheating and leakage)
3
Short-circuit prevention: Ensure + and - terminals do not touch metal materials to avoid short-circuiting (may cause fire, heat, or leakage)
4
Installation: Do not reverse polarity (+/-) when inserting into devices; use spring terminals with nickel/gold plating and contact force ≥0.5N
5
Storage: Keep in 10-30°C environment with humidity ≤60%RH; avoid direct sunlight and high-temperature areas
6
Inspection: Perform incoming inspection within 30 days of receipt; notify Seiko immediately if defective products are found
7
Child safety: Keep away from children (risk of swallowing); if swallowed, seek medical attention right away
8
Leakage response: If leakage or strange smell occurs, keep away from fire to prevent electrolyte ignition
