Too bad, wrong Kapazitäsangabe and no protection circuitry.

I have now a larger collection of 18650 batteries and thus run my flashlights.
It also several batteries UltraFire 3000 mA / h in use, they are used in lamps with power consumption of about 1.7 ampere.

Positives:
- Inexpensive

Negatives:
- The inscription on the case suggests that it should be protected by cells, which is in my battery is not the case! No protection circuit as in the case printed!
- Capacity is not reached in this current drain even begin. I'll be computationally less than 1000 mAh (at 1 A)

It may be that it works better at lower current consumption, but to suggest to the customer a protective function, which de facto does not already exist, is negligent.

It is recalled that Li Ion cells are operated in a voltage window (typically 2,75-4,2V), and also not be short-circuited. At worst, it comes to fire or explosion. Who handles these batteries as unprotected while the usual safety guidelines may thus be considered fortunate or with the low capacity. For me, these cells no longer come, in spite of the prices in question.
