To extend a blu electronic cigarette's battery life, disconnect the cartridge or cartomizer from the battery when not using the product. Moreover, when using an electronic cigarette, do not fully drain the battery, avoid overcharging it and make sure to charge batteries before storing them away for future use.
Batteries for blu e-cigs are available in several different sizes. The standard battery lasts for approximately 80 to 100 puffs, the Premium100 battery lasts roughly 150 puffs, and the Universal Plus+ battery lasts between 200 and 240 puffs. The company also offers a number of disposable products as of 2015, though none of these are rechargeable.
