You are responsible for your own safety!

These batteries are designed, manufactured, and sold only for use in a battery pack with the proper protection circuitry and battery management system. They were not designed for vaping (electronic cigarette) use or for use without protection circuitry. Use of these batteries is AT YOUR OWN RISK!

Misusing or mishandling lithium-ion batteries can pose a SERIOUS RISK of personal injury or property damage.

  • Only buy batteries from a known, trusted vendor of genuine batteries.
  • Never use a battery, charger, or device that is not in perfect working order.
  • The plastic battery wrap and top insulating ring must always be kept in perfect condition to prevent short-circuiting of the battery which can result in the battery bursting.
  • Never exceed the battery's continuous discharge rating (CDR) or charge rating.
I am not responsible for any damage or injury sustained by anyone using this table to select a battery.

The table below only notes the ratings for batteries at the time I tested them. For any battery not in a Samsung, Sony, LG, Panasonic, or Sanyo plastic wrap the battery being used can change at any time! This is one of the hazards of using “rewrapped” batteries. To avoid this issue only use genuine Samsung, Sony, LG, Panasonic, or Sanyo batteries in their original plastic wraps.


Here are the ratings for the 20mm and 21mm diameter batteries:
