This rechargeable Aspire 21700 battery is designed for use with devices that accommodate this bigger type of vape battery. This 4000mAh battery is Lithium ion, which is a safer option compared to other types. In addition, the Aspire 21700 offers speedier discharge rates and is ideal for high power, performance intensive vape pens and mods. As always, when they're not in your kit remember to safely store your batteries away from metal items such as keys or coins, we highly recommend a specifically designed 21700 battery case.
