Battery test 18650, common curves for all tested batteries
This article has curves for all tested batteries that are around 18650 size. These curves are not easy to read due to the huge amount of curves in each chart. For this reason there is also 3 other articles with curves, each one has 1/3 of the curves. The split is done according to the capacity at 1A load.
All curves used are from the A battery in the tests.

Capacity at different currents
In these curves the capacity is measured from a fully charged battery down to 2.8 volt with a constant load current.
Discharge time in hours at different currents
In these curves the time is measured from a fully charged battery down to 2.8 volt with a constant load current.
Discharge time in minutes at different currents
In these curves the time is measured from a fully charged battery down to 2.8 volt with a constant load current, but I have changed the scale to show the shorter discharge times better.
Energy at different currents
In these curves the energy is measured from a fully charged battery down to 2.8 volt with a constant load current.
Energy includes both current and voltage in the same measurement and is a better indication of what the battery can do.
