Safety Warning for Lithium-Ion Battery Usage
Customers should have a clear understanding of lithium-ion battery handling and safety before making a purchase. Lithium-ion batteries are highly sensitive and may pose fire, burn, or explosion risks if improperly handled. Always charge batteries on fire-resistant surfaces, and never leave them charging unattended.
By purchasing, you assume full responsibility for any injury, damage, or loss arising from incorrect use or handling. Only charge with a smart charger for this chemistry, and do not mix old or used batteries with new ones. Use within a protected pack; do not solder directly to cells; spot welding only. Inspect wraps and insulators. Do not expose to heat or liquids. Do not puncture or crush. Resellers must pass safety information to end users.
