Product Description

You are looking at a Four PACK of 18650 batteries PLUS a charger.

This is a Lithium ion 18650 battery, generally used in some LED flashlights, robotics, portable cell phone chargers and E-cigs. You should ensure that whatever you are putting them in, does not exceed the recommended discharge rate for the battery.


  • High quality Ultra Fire 18650 battery
  • 3.7V
  • ~2000 mAh or less
  • High energy density
  • Color may vary
  • No "memory effect"
  • Low reoccurring operation cost
  • Short-circuit and over-current protection
  • Shelf-life of roughly 10 years
  • More environmentally friendly because of rechargeability
  • Standard discharge rate of 0.25C or LESS. Meaning they can provide around or less than a current of up to one amp for four hours, or two amps for two hours.


MARKED BATTERY CAPACITY NOTICE: These are NOT nice Samsung/SDI, Japanese cells. They are made in China. They almost always lie about the rated capacity on the battery. The label they stick on should NEVER be trusted. As a general rule, no matter what the text on the side of the battery claims, they are usually around 2000 mAh per battery or LESS! Maybe a little more, maybe less, we have no way of testing. But for the price, they are pretty useful battery cells. If you are working on a budget and need power for your project, you can't really do better than the these cells. If you want higher quality batteries, with genuine ratings printed on them, you can contact us and we can get some genuine Samsung or Japanese 18650s for you. But they will be MUCH, much more expensive per single cell.


SAFETY NOTICE FOR ALL Lithium Batteries:

For either Li-ion or Li-po batteries. Never short these batteries. Never store or transport with conductive items. You should ALWAYS charge safely. Never charge at a higher rate than you are supposed to. Never discharge at a higher rate than you are supposed to. Never leave un-attended when charging or discharging. Never puncture or crush the batteries. Never over charge or over-volt the batteries. When you buy a lithium style battery from Vetco, it is assumed that you know what you are doing. Vetco can neither educate you or accept any liability for the use or improper use of any style of lithium battery.
