Firefly Replacement Battery description


This replacement battery pack is compatible with the Firefly 2 and Firefly 1 Portable Vaporizer. The battery works as a replacement for lost or damaged batteries and can also be used as a spare so that you're never out of power.


Lithium ion batteries are the standard battery for high quality vapes, their power and reliability boost the performance of any vaporizer they are powering. With their staying power (a lithium ion battery can go through about 300-500 charging cycles) lithium ion batteries can make your vape last much longer than originally intended. Making sure your Firefly replacement battery is the manufacturer's authorized replacement is a small step to make sure your vaporizer is working at its intended level of performance.


  • 1. One of the more enjoyable ways to take care of your Firefly replacement battery is to just simply use your vaporizer. The easiest way to maximize the lifespan of your e-cigarette is to regularly use your product. When you regularly use your device, energy is able to constantly flow through the battery. The constant flow of energy keeps the lifespan long.
  • 2.Keep your battery cool. Lithium ion does badly when exposed to high heat, and anything above 86° can tweak the performance. Make sure to never leave your charging Firefly replacement battery in a hot car.
  • 3. Make sure your Firefly replacement battery is kept clean. The batteries used in vaporizers are constantly exposed to the oils and dirt on your hands, this helps attract particles of debris that will latch onto the oil and stay on your battery. By regularly disassembling your Firefly and cleaning the battery and surrounding areas, you are helping to extend the life and strength of your battery.
  • 4. Don’t overcharge your Firefly replacement battery. While it is tempting to leave your battery on a charger overnight charging your vape while you sleep can limit battery performance and reduce its overall lifespan. Your battery will be damaged if it gets a full charge and continues to charge even more. It is best to charge your battery until it is full and then remove the battery from the charger.
  • 5. For extended storage keep your replacement battery at around 40% and store it in a cool place. If you store your Firefly replacement battery at 100% if will start to oxidize at its highest rate. Storing lithium-ion batteries at 40% discharge and in the refrigerator (not freezer) is recommended.

    New battery makes a world of difference!
    by Paul Lyons

    I've used my Firefly daily for the past 18 months. Its original battery was shot. It had probably needed replacement for a while.

    This new one is great! It totally restored my Firefly's performance.

    Definitely worth it!

    Discovered that I had actually purchased the battery from another company.
    by Patrick

    I mistakenly gave you folks a bad review and I want to say sorry for that. the battery was bad and my original battery failed as well but it wasn't your fault. Maybe the replacement battery was inferior, I got it on Ebay with another company. Anyway sorry about my earlier review. Patrick
