Polymer Lithium Ion Battery, 18650 Cell (3.7V 2600mAh)

No, these aren’t some sort of weird, blue AA battery, this is actually a 18650 Lithium Ion Cell. These round high capacity cells have been mainly used in flashlight type applications but with the capability to be used as a drop-in rechargeable cell at 3.7V with a capacity of 2600mAh. This is a great battery option for those of you who need a simple to install and replace cell with a lot of juice.

The current draw for lithium batteries is usually quoted as a proportion of the battery's capacity, these 18650 cells have a continuous discharge current of 0.2C and a peak discharge of 1C. This translates to a continuous current output of 520mA and a peak output of 2600mA. Operated within these limits you can expect to get around 300 charge cycles over the lifecycle of the cell.
