| E-cig batteries deliver power to the atomizer to turn the e-liquid contained in the cartridge to a vapor. 510 e-cig batteries are some of the most reliable in the world. Manual batteries tend to be more reliable, give more control over the length of puff and don't activate unexpectedly when jarred or jostled. We no longer sell automatic batteries due to their high failure rate caused by liquid leaking into the electronics. Batteries can last for up to a year or more but will lose charge life (time in between charges) after a couples months. The Charger Case takes away the hassle of constant recharging of older batteries. Please refer to the Manuals & FAQS of our website usage information. |
