The Samsung 25R 2500mAh INR 18650 Battery is the most recent battery released from Samsung. This 2500mAh battery uses a "Safer" INR chemistry. Low internal resistance and a maximum continuous discharge rating of 20amps make the Samsung INR 18650-25R Battery a great choice for any vaper using builds above 0.2ohms. We recommend the Samsung INR 18650-25R for use with tank systems whose total resistance measures @ or above 0.2ohms. These batteries are high capacity, high discharge current cells. The batteries can cause serious injury or property damage if mishandled or mistreated.

    Battery safety is very important. Mistreated batteries can get extremely hot and/or vent which could cause injury. Always follow the following rules to make sure this doesn't happen. We are not liable for mistreated batteries.

    • Never completely discharge batteries (below 2.5V under load or 3V unloaded)
    • Charge fully (to 4.2V) before first use
    • Never use a lot of force on the battery to install
    • 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
    • Be mindful of the current limits in the specification and never exceed them
    • Never keep spare battery or batteries loose in or near;
      • Pocket etc
      • Purse etc
      • Vehicle glovebox or console compartment, in fact never in a vehicle
      • Direct sunlight
      • Machinery
      • Fire or heat sources
    • If storing batteries short or long term, use these guidelines
      • Use a battery model specific protective case, found here
      • Use a cool & dry environment
      • Don not store fully charged, approximately 3.6~3.7V is best
    • Never try to charge or discharge li-ion batteries with battery chargers that are not made for Li-ion batteries
    • Never charge battery 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)
