⚠️ Safety & Handling

Battery Safety Warnings & Guidelines: Improper use may result in fire, injury, or damage. Always follow these precautions:

• Use only a Li-ion charger rated for 4.2V CC/CV charging
• Charge fully before first use. Never charge unattended
• Do not short-circuit, reverse polarity, or exceed rated current
• Inspect before each use. Stop using if wrap or insulator is damaged
• Do not expose to heat, water, or direct sunlight
• Do not disassemble, modify, or solder directly onto the cell
• Store in a protective case-never loose in pockets or bags
• Do not mix old and new cells. Do not force installation
• Discontinue use if cell emits odor, heat, or changes shape
• Keep away from children and pets
• NOT for use in E-Cigarettes or Vape Devices
