Warning

Lithium-ion batteries require proper handling and knowledge to ensure safe operation
Failure to follow safety guidelines may result in fire, explosion, serious injury, or property damage
Only purchase and use if you fully understand lithium-ion battery safety
Never leave a battery unattended while charging
Keep away from animals and children
Prevent contact with metal objects (keys, coins, tools) to avoid short circuits
Inspect wraps and insulators regularly for damage - repair or dispose of damaged batteries immediately
Resellers must pass these warnings to customers
Typical cycle life of 200-500 cycles before noticeable capacity reduction - recycle at end of life
Do not crush, incinerate, or modify batteries
Only use within manufacturer specifications
