Test/Review of Efest 18650 3400mAh (Black)
Efest 18650 3400mAh (Black)
Protected button top Official specifications:
The protection does prevent a full 5A discharge curve on one of the batteries. The difference in protection between the batteries is also the reason for the curves not overlapping at the higher currents. The cell used can be discharged down to 2.5 volt, in my test I only discharges to 2.8 volt, i.e. I do not measure the full capacity. But then, not all lights will be able to use the full capacity. Unprotected flat top Official specifications:
The unprotected version has exactly the same very good performance as other batteries with the same cell. Conclusion Both batteries are very good, the slightly low protection limit is only a problem in special applications (Discharing a 3400mAh battery in less than 40 minutes is not normal usage), not for regular usage. Notes and links How is the test done and how to read the charts How is a protected LiIon battery constructed More about button top and flat top batteries
