Initial Charge: Fully charge the cells using a dedicated, high-quality lithium-ion smart charger before their first use.
Proper Alignment: Verify the positive (+) and negative (-) ends align correctly with the markings on your device or charger before insertion.
Storage & Care: Store spare batteries in a cool, dry place. Keep them inside a plastic battery case if removed from the package to prevent the terminals from touching metallic objects.
Safety Precautions: * Do not crush, puncture, incinerate, or short-circuit the external contacts.
Do not expose the batteries to extreme temperatures or direct sunlight (keep below 45°C / 113°F).
Warning: Keep out of reach of children. Inspect the battery sleeve/wrap before every use. Never use a battery with a torn, damaged, or peeling protective plastic wrap. Use only chargers specifically certified for 3.7V Li-ion cells.
