Samsung Battery – What is it in Vaping?

Definition

A Samsung Battery is a high-drain lithium-ion cell manufactured by Samsung SDI, widely adopted in vaping devices for its reliable continuous amp output and stable voltage curve. Unlike generic cells, Samsung batteries are engineered to withstand the low-resistance demands of Sub-Ohm tanks and high-wattage Squonk Mods, delivering consistent power until depletion. Vapers choose Samsung-branded cells to ensure ample headroom above a mod’s maximum draw, reducing the risk of overheating while prolonging overall cycle life.

Technical Details

Samsung’s most popular vaping cells are the 18650 form-factor (18 mm diameter × 65 mm length). Flagship models include the INR18650-25R (2500 mAh, 20 A CDR) and the INR18650-30Q (3000 mAh, 15 A CDR). Both use nickel-based lithium-ion chemistry (INR) for lower Resistance“>internal resistance and reduced voltage sag under load. Internal PTC resettable fuse and CID (current interrupt device) provide passive Short Circuit Protection. Nominal voltage is 3.6 V, with a 4.2 V peak charge and 2.5 V cut-off. Energy density reaches ≈ 200 Wh kg⁻¹, allowing compact Starter Kit designs without sacrificing run-time. Always verify the authenticity hologram and batch code on the steel can—counterfeits often over-state ratings by 50 % or more.

Usage & Tips

  • Married pairs: buy cells together, label them, and always charge/discharge as a set in dual-battery mods to prevent imbalance.
  • Keep wraps pristine; nicks or tears require immediate re-wrapping to avoid hard shorts against the mod’s battery tray.
  • Store at 3.7 V (≈ 40 % charge) if not used for weeks; prolonged full charge accelerates capacity fade akin to over-Steepinge-liquid degrading flavour.
  • Never exceed the Continuous Discharge Rating (CDR); calculate max amp draw using Ohm’s Law: I = V ÷ R. When in doubt, build above 0.2 Ω for 20 A cells.
  • Use an external charger with independent bays; while most modern mods balance-charge, external units offer better termination accuracy and extend Samsung battery life past 300 cycles.

History & Context

Samsung SDI began mass-producing high-drain 18650 cells for power-tool makers in 2010. The vaping community quickly adopted the 20 A 25R when mechanical tubes surged in popularity, establishing Samsung as a trusted name alongside Sony and LG. Continuous iterations—20 R, 25 R, then 30 Q—mirror the industry’s shift toward higher capacity without sacrificing amp headroom, supporting today’s 200 W regulated boards and temperature-control suites.
