Safety Warning for Lithium Battery Usage
Customers should have a clear understanding of lithium battery handling and safety before making a purchase. Lithium 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.
- Not for Use in E-Cigarettes or Similar Devices
- Risk of Fire and Explosion: Misuse can cause batteries to ignite, explode, or release harmful gases.
- Always Use in a Protected Pack with appropriate BMS circuitry.
- Proper Storage and Handling: Store in protective cases, away from metal items.
- Inspection Prior to Use: Do not use batteries with damaged wrappers or visible damage.
- Follow Manufacturer Charging Specs: Avoid overcharging or over-discharging.
- Heat and Water Precautions: Do not expose to high temperatures or liquids.
- Assembly: Batteries should only be spot welded; do not solder directly onto terminals.
For Resellers: Please ensure all safety information is passed along to end users.
