The Batteries are rated at 650mAh which will provide 7-14 hours of use per charge.

eGo Batteries have a Manual Button (Switch) that allow you to activate your Clearomizer and produce vapor as needed.

We have also added a 5-Click On/Off function which can help prevent unwanted or unintentional use by simply pressing the manual button 5-times in a row to turn the battery "On" or "Off".

eGo 650 mAh Manual Button Batteries use the most popular thread style available, the 510/eGo thread, which will allow you to use a wide variety 510/eGo threaded Atomizers, Cartomizers, and Clearomizers.

Important Note:  Before use, please charge your eGo batteries for approximately four (4) hours.  After the initial four (4) hour charge, it is BEST and ALWAYS recommended to remove your battery from your charger as soon as they are fully recharged (light turns green on the USB charger).  Overcharging your batteries will decrease the overall lifespan of your batteries.
