Joyetech has created the standard for vape pen batteries. Their upgrade battery has a variable voltage feature which will automatically adjust for a consistent output all the way through the batteries life. So where other batteries will produce a weaker puff towards the end of the battery life cycle, the Joyetech variable voltage upgrade battery will automatically boost itself so that the last puff is just as good as the first.
To switch between constant voltage and variable voltage modes first place the battery into the protection mode by tapping the button 5 times. The indicator light will blink 3 times to show that it is locked. While locked hold the button down for 6-7 seconds and you will see the light change colors. An orange light indicates that the battery is in variable voltage mode while a white light indicates that the battery is in constant voltage mode. Clicking the button 5 more times will unlock the battery for use.
Like all genuine Joyetech products the 1000mAh upgrade battery has the official Joyetech logo etched on the bottom and "eGo-C Upgrade" printed on the side.
