18650 Batteries


What is an 18650 Battery?

An 18650 Battery is a lithium-ion rechargeable battery. The first 4 digits of the designation “18650” indicate the physical dimensions while the 5 th digit indicates it is a cylinder cell. The standard 18650 battery is 18mm around by 65mm long. This type of battery is very common in applications such as laptop battery packs, flashlights, electric vehicles, cordless tools and various other devices that require portable power.

Some types of 18650 have been modified adding either a button top and/or internal protection circuit. This can increase the physical length of an “18650” battery from 65mm to 70mm or in certain cases even longer.

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.
