The battery is called 18700, because it is nearly 70 mm long, but protected 18650 can be just as long, only unprotected batteries are 65 mm long.

The protection does not allow the battery to sustain 5A current draw.

[size=+3]Conclusion[/size]

This battery is best for lower load and easily holds the specified capacity.
It is using a unspecified cell, but with Xtar behind it I will call it good battery.
