18650 Batteries

Choose from our wide selection of 18650 batteries. Some things to consider when choosing a battery:

  • Style
    • Flat Top - The positive end of the battery is a flat surface.
    • Button Top - The positive end of battery is protruding.
  • Nominal Capacity
    • This is the minimum capacity of the battery.
    • Capacity is measured by mAh (Milliamp Hours).
    • mAh is a unit for measuring electrical power over time.
    • A higher mAh rating means the (fully-charged) battery can power a device that consumes more power and/or for a longer amount of time before becoming depleted and needing to be re-charged
  • Continuous Discharge Rating
    • The maximum current at which the battery can be discharged continuously without damaging the battery or reducing its capacity as defined by the manufacturer.
  • Pulse Discharge Rating
    • The maximum current at which the battery can be discharged for a short period of time without damaging the battery or reducing its capacity as defined by the manufacturer.
  • Nominal Voltage
    • A value assigned for classification purposes. Operation may actually be possible within a range, and the nominal voltage is often the midpoint of that range.
  • Protected
    • Protected batteries have a small electronic circuit integrated into the cell packaging. This circuit protects the battery against common dangers, such as overcharge, over discharge, short circuit/over current, and temperature. Please keep in mind a protected battery will be slightly longer do to the integrated circuit.
