  • ICR18650-20B
  • ICR18650-20C
  • ICR18650-20F


These are used cells. They were charged to 4.2v, left to sit for at least one week, then discharge tested at 500mA. We may wrap cells in new heat shrink if the original wrapping was significantly damaged. These may still be delivered with adhesive or tape still attached, or damaged heat shrink. Check out or selection of pre-cut heat shrink and adhesive rings to customize your build.



*Our charger/testers have a range of 2.8 - 4.2v; we find that manufacturers often specify a greater range (2.5 - 4.35v, for example), especially on higher-capacity cells. We make slight adjustments for 'effective capacity' to account for this. Capacity is written on each cell.
