Lithium-Ion cells should be charged on a dedicated charger rated specifically for Lithium-Ion cells.Â
Never leave a battery unattended whilst charging.Â
Keep away from animals and children.
Wraps and insulators should be periodically inspected for tears or damage. If a battery has a damaged wrap, it should be repaired or disposed of immediately.Â
If you are re-selling these cells, it is your duty to pass these warnings onto your customers.
Batteries usually have a cycle life of between 200-500 cycles (varies with manufacturer) before noticeable capacity drop off. Batteries should be recycled at this time.
