    As always, you can trust Liion Wholesale to have tested random samples from each and every batch to make sure all the batteries are fresh and genuine.  Anyway we have an agreement with Efest themselves and buy only manufacturer direct for these so the chances of issues are small, but we test anyway.  You won't get that with most suppliers.


    Batteries are sold individually.

    Battery Warning

    Warning: Lithium ion batteries may explode or burn due to improper use. Using these batteries for purposes not intended by the manufacturer, including outside a battery pack and/or without a BMS, may cause severe injury and damage. We are not responsible for any injuries caused by lithium ion batteries - use at your own risk.

    All rechargeable batteries have inherent risks under any circumstance. Use caution with working with li-ion batteries (lithium-ion), LiPo (lithium ion polymer), and any rechargeable cells (together "rechargeable batteries"), as they have dangerous charging characteristics and are known to explode or burn if mishandled. A purchaser and user of rechargeable batteries should educate themselves on rechargeable batteries, especially as to charging, discharging, assembly, and storage. Learn more about proper storage and care for rechargeable batteries here. We are not responsible for any damage caused by the misuse or mishandling of rechargeable batteries.

    Here are a few tips:

    • Never completely discharge batteries (below 2.5V under load or 3V unloaded)
    • Charge fully (to 4.2V) before first use
    • Never charge batteries to 4.3V or above
    • Do not charge unattended
    • Do not store your li-ion batteries fully charged for an extended period of time (weeks or more)
    • If you must store your battery, only store in a case or individual box in a cool and dry place at approximately 3.6-3.7V
    • Use only high quality battery chargers
    • Do not expose to heat
    • Do not connect the positive contact to the negative contact without an appropriate load
    • Never exceed the battery's specifications
    • Never try to charge or discharge li-ion batteries with battery chargers that are not made for li-ion batteries
    • Always charge these batteries on and within fireproof material
    • Never leave rechargeable batteries in a recharging station unattended
    • Do not use any rechargeable battery or charger if any visible damage is present, or if known mishandling, accidental or otherwise, has occurred
    • Always store and transport rechargeable cells in a safe, non-conductive container (never keep a spare battery loose in a pocket, purse, etc. and always use protective cases)
    • Properly dispose of all battery cells and chargers in accordance with local laws and mandates (if you're unsure, contact your local municipality)
    • If a rechargeable battery overheats, hisses, or bulges, immediately quarantine the battery from any combustible materials - ideally, take the battery outside
    • If a rechargeable battery catches fire, the FAA recommends pouring water or soda on the battery and surrounding areas - ideally, use a foam extinguisher to quell the fire

    Very good IMR 14500 cells.

    • What device/application do you use this with? LED flashlights
    Good Stuff Maynard

    These are just what the doctor ordered! Provides plenty of amps to keep up with the draw of today's modern LED flashlights. Jetbeam E10R choked protected 14500's @ 2A, these cells pump out multiple times that amperage and last a surprisingly long time. Haven't seem a *button top* purple EFEST 14500 IMR listed anyplace else and was wary they may be fakes/rewraps, but the labels check out at EFEST site and performance is top notch. A+ cells and service.

    • What device/application do you use this with? Thrunite TH20 headlamp
    Genuine high quality cell

    Has Efest scratch code to confirm authenticity. Works much better in my Thrunite TH20 than the Sanyo 840mAh I had been using, no voltage sag with the Efest.
