When it comes to vape pens, Joyetech is always pushing the limits to make their products better. Where other batteries become weak towards the end of their life cycle, Joyetech's Upgrade battery has a variable voltage feature which solves that problem. As the life of the battery depletes it will automatically provide a boost to keep the voltage output consistent. This way your last puff is just as good as the first puff.Switching from constant voltage to variable voltage modes is as easy as a few pushes of a button. First lock the battery by pressing the button 5 times. The indicator light will blink 3 times to show that it is locked. Now hold the button for 6-7 seconds until the light change colors. A white light means that the battery is in constant voltage mode while an orange light indicates that it is in variable voltage mode. Click the button 5 more times to unlock the battery for use.Like all genuine Joyetech products the 900mAh upgrade battery has the official Joyetech logo etched on the bottom and "eGo-C Upgrade" printed on the side.
