You may find there are different methods to label the nominal energy of 1.5V AA/AAA Li-ion batteries in the market. It's confusing sometime. To help you better understand and choose the right battery. We bought some rechargeable 1.5V AA/AAA Li-ion batteries from different reputable brands and tested them with the professional capacity grading machine in a standard lab environment. Based on these data, we summarized the four most common energy labeling methods. The specific analysis is as follows. And Please check more details on our website:

Mega Review of XTAR 1.5V Li-Ion AA 4150mWh/ 2500mAh Battery & L4 Charger by Dr. Gough Lui

Dr. Gough Lui made two months of 24/7 testing, data analysis spanning gigabytes of log-files and numerous experimental set-ups to learn just how the 1.5V Li-Ion rechargeable cells perform, how they hold up under long-term cycling, how they compare against ordinary Ni-MH cells, how they are built, how they are charged, how efficient are they and what their output voltage is like.

It is very confusing for an average consumer. The more someone tries to explain mwh vs mah, it get even more confusing. It would be a lot clearer if it went by reserve capacity, the same way pb batteries are rated. Basically how long cells will run under 1A load before they drop to 1.1v compared to alkaline under same conditions, this way it would be a lot clearer how they compare to alkaline or other cells in real world.
