100% compatible with eGo and eGo-T

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

3.3v Rechargeable battery with 1000mah capacity will last a very long time between charges. 

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

We may substitute an eGo-C upgrade battery if sold out of the standard eGo-C battery in the color chosen. The only difference is in the upgrade version is the ability to change between regulated and unregulated as outlined below. When in regulated mode they operate exactly as a standard eGo-C battery.

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.

New features on the eGo-C Batteries:

• eGo-C Batteries add a new dual LED feature that lets you know when the battery power is getting low.  When the battery has been drained to less than 20% power remaining the LED that lights up the button will change from White to Blue indicating that it needs to be charged soon.  This is a great feature that will keep you from having a battery die without notice while you are away from home.
• Strengthened short circuit and over discharge 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.
