what is high capacity 18650 Li-ion ? I am confused about it.

What are you confused about? A high capacity 18650 is just a battery that has a "high" capacity, with "high" being relative to other cells.

Does the word "high" refer to ampere?

am sure others will have better ways to explain it...

but to me - XX mAH capacity is like comparing it to gallons/liters of fuel your car gas tank can hold - the bigger the gas tank (ie. more gallons/liters it holds) - the more capacity it has and therefore more range you get in your car before you have re-fill the tank. (in this case - a recharge)

I have a couple of the 2900 mAH Panasonic 18650 that would give me a lot longer run time in my lights than a 1400 mAH 18650 cell - am not sure that it would give me double though :shrug:

High refers to capacity, which would be measured in milliamp hours (or possibly watt hours, which factors in the voltage). High drain batteries refer to cells that can handle a higher amp load.
