There is a lot of 18500 (18490) batteries in the market. Cheaper, more expensive, originals, clones, etc... But which one is THE BEST for my mech mod??
During last 2 years I've been testing it in various ways. Finally I found that the best way (as close as possible to reality, actually worse then reality :-) ) is continuous load test. Preferably at quite low "coil" resistance, lets say 0.5 ohm. So, I constructed test setup described here and started to test... Below you can see the results for 18500 batts:

The RESULTS
Having the voltage level during whole test and knowing the load resistance we can easily calculate the useful capacity of tested batteries. I emphasize the useful word because it is capacity calculated exactly for the conditions described in the test: for battery discharging from 4.2V to 3.3V at 0.5 Ohm load. In a different measurement methodology the total capacity will differ from this, BUT in my opinion presented methodology is the best from point of view the users of mech mods!
Recycling batteries leads to about 51.3% savings in natural resources, and not only because of decreased mineral dependency but also because of reduced consumption of fossil resources and nuclear energy demands. batteroo
