I consider all of these batteries used taken apart from packs, discharged at .2A and charged to capacity. All within 10% capacity.

IMR26700A Lithium Ion Batteries
Unlike Lithium Polymer batteries, these cells are very rugged. It is encased in a steel can similar to NiCAD/NiMH batteries.
Specs:
Dimension: 26mm diameter x 70mm length
Weight: Approximately 100g
Mfg Claimed Capacity: 2900mah
Nominal Voltage: 3.7 V
Charge Voltage: 4.2 V
Mfg's Max Continuous Discharge Rate: 20A
Max Tested Continuous Discharge Rate* : 45A (15C)
* Not endorsed by Manufacturer.
By eliminating cobalt from the IMR26700 cell it is possible to produce a much larger cell, while providing exceptional safety characteristics. Further developments of the IMR26700 cell will provide fast charge capability, allowing cells to be fully charged in as little as 15 minutes.
Cell Type IMR26700 Manganese
Size 26.4mm diameter; 70mm length
Weight 100g
Capacity 3Ah
Standard Operating Voltage 4.2V - 2.5V
Energy Density 285Wh/l
Power Density 1500W/kg at 20 seconds
