To charge your SERIES-E battery, unscrew the battery from the tank and then unscrew the beauty ring which sits at the top of the battery as well.

Keep this beauty ring safely in a place where you won’t lose it, as you need this for looks and stability of your SERIES-E.

Now you can screw the battery into your charger and plug your charger into your laptop, power bank or wall plug. A red light on the charger will show you that the battery is charging. When it turns green, your battery is fully charged. You can now take your battery off the charger, put the beauty ring back on and screw on your tank.

A fully charged SERIES-E battery will last approximately 8-10 hours, depending on which power setting is used.
