Test/Review of UltraFire SJ18650 6000mAh (Black)
UltraFire SJ18650 6000mAh (Black)
Official specifications:
This is a cheap battery from ebay with record breaking capacity according to its specifications. This is, of course, not correct. The battery can deliver about 1500mAh at low load, anything about 1A load is a problem and the two cells has different capacity. Conclusion There batteries are not very impressive, they can drive a low power flashlight, but only about half the time a good battery can. Also remember that these batteries are unprotected. I will rate this as a bad cell. 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 Compare to 18650 and other batteries
