100% compatible with eGo and eGo-T

**650mAh eGo-C upgrade battery pictured.  The 1000mAh version will be approximately 1 inch longer.

These genuine Joyetech batteries are universal and fit all eGo and 510 products. 

Upgrade batteries have the ability to change from regulated to unregulated mode.  To do so simply turn the battery off by clicking the button 5 times quickly.  Once off, press and hold the button until it flashes.  This means the other mode is now active.  Then turn the battery back on with 5 more quick clicks and you are ready to vape again.  

Regulated mode means that the battery's output is regulated to the standard 3.3volt output of a normal eGo-T or eGo-C battery.  The battery is in regulated mode when the button lights up white when pressed.

Unregulated mode means that the battery's output is not regulated.  Therefore, with a freshly charged battery the output will be close to 3.7v.  However, as the battery power is depleted, the voltage output slowly decreases as well.  The battery is in unregulated mode when the button lights up orange when pressed.

Other features and benefits:

Large 1000mAh capacity will last a long time between charges. Individual battery life is dependent upon usage.

These batteries have a safety switch that will de-activate the button so that the battery can be stored without accidently being activated. Simply press the battery button 5 times and the battery will be de-activated. Press 5 more times to re-activate it for normal operation.

These batteries are the same as the Joyetech eGo/eGo-T batteries with a few added features as noted below.

New Features on eGo-C batteries included

• Strengthened short circuit and over discarge protection
• Circuitry to prevent overcharging

***eGo Batteries should only be charged with a proper eGo compatible charger (output rating should be 420mA).  Compatible chargers include: eGo/eGo-T/eGo-C USB Wire Charger.  Use of other chargers (even if the battery will fit the charger) will void warranty and may cause battery to fail, become defective, or even explode.
