All our batteries and chargers are CE approved, however we always advise our customers a few points:
1, As with ALL rechargeable Batteries, Never charge batteries over night and never leave unattended while charging.
2, We recommend gently cleaning the connections and threading of the battery keeping it free of liquid and residue. This will ensure the battery remains in a safe working order.
3, Always use eMazing USB charger that comes with our kits with our batteries.
Important: When using the atomizer for the first time, make sure to let the E-liquid wick until the cotton is fully saturated before firing. This should take around 2-3 minutes according to E-Liquid thickness. This will ensure your atomizer does not burn out
