Lithium-ion battery cells may get extremely hot, explode or ignite, and cause serious injury if exposed to abuse conditions. Be sure to follow the safety warnings listed below.

  • DO NOT SHORT CIRCUIT. Short circuits may cause fire, and injury!
  • Charge battery fully to 4.2V before first use.
  • Use high quality charger specifically designed to charge Li-ion batteries.

  • Never attach any metal moving part |magnet| to the top-positive, or the bottom-negative battery contact.
  • Stop using battery with damaged PVC tube (wrap) or terminal insulator immediately.
  • If battery is damaged in any way stop using it immediately.
  • Never discharge a Li-ion battery at a rate exceeding the maximum discharge current specified for that battery.
  • Never use force to install (insert) li-ion battery.

  • Do not carry, or store the batteries together with hairpins, necklaces, or other metal objects.
  • Do not use with vaporizer, e-cigarette, or similar device.

  • After battery is discharged-don't leave it discharged-charge battery as soon as possible (10 min. rest time).
  • It is your responsibility to determine that your charger, and host device works properly.
  • On (battery electrolytes) exposure to skin, flush with water immediately.
  • If eye exposure occurs, flush with water for 15 minutes, and seek emergency care immediately.


What is short circuit?

Situation when battery positive (+) and negative (-) connect. The current will become extremely high because there is no resistance in the path to limit current flow. Short circuit will result in dangerously high temperature which may cause fire.



The use of any unprotected li-ion cylindrical 18650 battery as a stand-alone device, including with e-cigarettes, vaporizer pens or other products, constitutes a DANGEROUS misuse of the battery cells that poses a SERIOUS RISK of personal injury or property damage. These cells are only for prototyping with proper electronic protection circuits, and not for stand-alone use. 

These are high discharge current & high capacity 18650 Li-ion batteries. If mishandled or mistreated, these batteries can cause you SERIOUS INJURY. USE AT YOUR OWN RISK.

    Super authentic Samsung

    Posted by Joshua M. on Apr 24th 2017

    The Samsung 30Q's are excellent. Use nothing but Sony & Samsung batteries these days since I feel they're superior quality over all the hazardously dangerous knockoffs, with their highly exaggerated power ratings printed on the battery wrap. So just go ahead and purchase these 30Q's or Sony VTC 6 or VTC 5 right here at Orbtronic. All around excellent seller and top quality authentic products.

    Nice per and long life

    Posted by Nicholas R. on Apr 12th 2017

    These batteries are great. Very long life, and being used within their limits, they perform better than any 3000mAh battery I've used before. Only negative is their wraps tend to rip a little easy, but once rewrapped, no issues.
