Safe usage, storage and disposal

Lithium-ion (Li-ion/Liion) batteries/cells can be dangerous when mistreated.

  • Never carry loose cells – they should be suitably cased at all times when not in use. (We supply free cases with every order)
  • Do not short batteries with metalic objects.
  • Always use a battery charger designed for the cells you are charging. You can find ours here
  • Never leave a battery charger unattended.
  • Never completely discharge batteries. (The cut off for most cells is 2.8v or 2.5v)
  • Check your wraps and insulators regularly. Replace worn or damaged wraps before continuing use. You can see our selection here
  • Do not expose to extreme heat or cold, or sudden fluctuations between the two.
  • Always dispose of end of life cells at your local WEEE recycling centre or return them to us for free disposal.
