18650 Battery Review-Vape & Flashlight communities need some real battery tests.

 
18650 battery test-reviews is what I will start doing from the next week.
It will ne very interesting to see how 18650 batteries behave under different working conditions.
 
These bench tests and reviews will include:
  • Visual discharge graph (curve) at various continuous and pulse current loads.
  • Battery Amp limit.
  • Real capacity (cell will be discharged from full charge to the lowest voltage discharge cutoff limit).
  • Working temperatures during discharge in real time.
  • Original Battery Specs - datasheet from manufacturers.


You will be able to see the actual performance of the battery cell (in various situations), that you might be using already or that you would like to buy somewhere online but not sure about performance.

Why am I doing this?
 
Answer: Safety!
 
It is getting out of control.
 
Flashlight community is pretty much safe, because 99.9% of today's LED flashlights are running on 18650 Protected batteries.

One, and only independent battery tester is HKJ. You can trust his extensive Li-ion testing 100%.
 
The lithium-ion safety risk is the highest in vape (electronic cigarette) community that is growing very fast.

Lack of proper li-ion 26650,18650 battery knowledge is the biggest enemy for average vape (ecig) end user (vaper).

To make this already dangerous situation for vaping users even more risky we can see more, and more companies (usually Chinese) releasing unprotected vape 18650, and 26650 batteries with exaggerated Amp limit rating numbers. Sometimes 500% over actual battery Amp rating.
 
It seems that box mod e-cig batteries are becoming good source of income for individuals who represent themselves as "independent" battery testers.

I will talk more about these "unbiased" battery tests too, and what tricks they use to make battery performance bad, or good.


Just some of the 18650 batteries that will be tested with very accurate (lab calibrated) computer battery analyzer:
LG HG2 
LG HE2 and HE4
LG HD2 and HD2C
LG HB6 
Samsung 30Q , 25R, 20R
Sony VTC4
Sony VTC5, VTC5A
Sony VTC6
Panasonic NCR18650GA, NCR18650B, NCR18650PF, UR18650NSX

Some very good, and some really really bad, and dangerous rewraps will be tested as well.
Many more batteries will be tested and posted on this blog. This is just a beginning...

    1. 18650 battery review should be independent, and accurate. Unfortunately, most vape battery tests are secretly sponsored by various online stores.
      That is the Nr.1 problem - there is no independent tester in vape community.
