Your SERIES-E battery has safety features built-in, such as a 8-second cutoff. Also, if it's unsafe for the battery to fire, it will refuse to do so and the lights around the button will flash.


However, please be aware of the following to ensure that you're using your battery safely:


  • Don't use the battery, charging cable or adaptor if any of them been visibly damaged.
  • Activate the five-click lock when the battery isn't going to be used for a prolonged period of time or if you're putting it into a bag or pocket.
  • Don't leave the battery to charge unattended or overnight, and leave it to charge on an inflammable surface.
  • Be sure to use suitable charging cables and adaptors; fast-charge mobile phone adaptors are not suitable.
