With our extensive range of 18650 batteries, you can use our instructions to help you find the right, safe battery for your use. 18650 batteries differ in terms of protection and power supply capacity, but there are also differences in reloading volumes.
IMR or Lithium-ion Manganese Rechargeable
The IMR labeling on the battery means significantly ICR battery chemistry for better reloading. Typically, a 18650 ICR battery is able to supply current momentarily around 5A, with IMR batteries this value is multiple.
The maximum power supply is expressed as amperes (A), either instantaneous or continuous.
Rules of thumb in the 18650 battery world:
The maximum capacity is 3500mAh due to the physical size of the 18650 battery.
The more capacity, the lower the power supply.
The maximum current of a 3500mAh battery is usually 10A.
The compromise between power and capacity is 3000mAh and 20A, such as LG HG2 and Samsung 30Q.
Unprotected, even-headed batteries are typically used in devices with proprietary electronics that also protect the battery. Such equipment includes vacuum cleaners and power tools.
The flashlight you want a protective batteryto prevent the battery from dischargeing too empty (less than 2.5V). You can find the protective circuit batteries here: Batteries with a protective circuit.
Unprotected IMR batteries are ideal for evaporation.
