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 the incorrect use or handling of lithium-ion batteries or chargers. Compatibility with specific devices is not guaranteed. Only charge using a smart charger designed specifically for this battery type, and do not mix old or used batteries with new ones.
Important Usage Guidelines:
- Not for Use in E-Cigarettes or Similar Devices
- Risk of Fire and Explosion
- Always Use in a Protected Pack
- Proper Storage and Handling
- Inspect Batteries Before Use
- Follow Manufacturer Charging Specifications
- Avoid Heat and Water Exposure
- Spot Weld Only – Do Not Solder Directly
Users are expected to have battery-handling knowledge before purchasing. By using these batteries, you acknowledge that usage is solely at your own risk and you take full responsibility for any resulting consequences.
For Resellers: Please ensure all safety information is passed along to end users to promote safe handling and proper use.
Orders ship from Florida when inventory is available. Lithium-ion cells require proper handling, protected packs, correct chargers, and safe storage. Do not solder directly to battery terminals.
