Disclaimer On Use Of Batteries


Batteries must:

  • Be charged correctly: The current and voltage used to charge the batteries must not be greater than is set out in the instructions. Batteries should not be charged in excessively cold or hot temperatures. Do not leave the battery in the charger for over 24 hours. Do not leave the battery unattended whilst charging. Never use a modified or damaged charge.
  • Use the correct discharge current: The discharging current shouldn't exceed the level set out in the instructions. If it does this may cause the battery to overheat.
  • Store the batteries at the right temperature: batteries should be stored at an ambient temperature in dry, well-ventilated conditions. You should avoid excessive hot or cold.
  • Keep your batteries in a case when not in use. Don't carry them around loose in bags or pockets: It's vitally important that batteries do not come into contact with any metal objects as this can lead to leakage, explosion or fire.
  • Not be used if they are damaged, abnormally hot, discoloured, deformed, if the wrapping is not intact or if any other abnormal conditions are detected. Dispose of the batteries if this occurs.
  • Not be allowed to come into contact with water or fire. Dispose of the batteries if this occurs.
  • Not be put in microwave ovens or in any high pressure container.
  • Not be used or assembled with other different makes, types or models of batteries.
  • Avoid excessive physical shock or vibration.

If liquid leaking from a battery gets in your eyes, don't rub your eyes, wash them with clean water and seek medical attention immediately. Ensure that the battery is disposed of immediately and that any liquid that has leaked from the battery is contained and removed as it may cause explosion or fire.

Each country has its own rules on the disposal of batteries. Please ensure that you dispose of the batteries in accordance with local regulations.

Molicel 21700 (09 August 2021)

I previously used Molicel 18650 & i was quite impressed with the performance & price. I use a nunchaku 2 that has the option to use 21700 so i thought i would try them. My Mod Using a single battery i wanted extended my vaping time. 21700 certainly gave me more vape time around 2 hours more. I can take one 21700 battery to work instead of the 2 18650 & the one 21700 last my shift.

Great performance and long lasting batteries. Used to constantly be charging 18650s but I bought a pair of these and never go through both in a day.

Great battery, performs really well in a single pen mod at lasting a long time

By Tony from Hemel

Measure your battery (04 January 2020)

Bought to replace my 15 month old pico squeeze battery. This is only 1 mm shorter then the original battery but it rattles and the mod screw cover goes So tight I now need a pair of grips to remove the cover&battery. Didn’t think to measure the battery just used the battery number for reference. Power wise: It last a Bit longer but no where near like the original.

By P from Cambridgeshire.

Great batteries. (11 September 2019)
