Why the Samsung 25R Defines Reliable Performance

The Samsung 25R cell holds a celebrated position in the vaping community, recognized globally for its craftsmanship and unwavering power delivery. It is a genuine high-current workhorse, designed not for “monster” wattage, but for steadfast, reliable performance that you can count on every single day.

The cell’s internal chemistry has been optimized for both discharge rate and capacity, striking the perfect balance between power output and usable run time. This balancing act is precisely why the 25R has remained a go-to choice for regulated devices that pull up to 20A continuously. It features a robust design that ensures thermal stability and safety, even under sustained high-drain use, which is critical for your safety and device longevity. Its consistent performance means you will experience fewer power dips and more stable vapor production throughout your session. The proven history of the 25R shows you that dependability always beats flashy specifications.

This cell is best for any vaper using a regulated mod who prioritizes safety, consistency, and a proven, reliable power source.

Mastering the Specs: A Guide to the 25R’s Real-World Benefits

  • Cell Type/Size: 18650 Cylindrical Cell – This standard size ensures compatibility with the vast majority of regulated mods and kits on the market that use removable batteries.

  • Nominal Capacity: 2500mAh – Provides a reliable and substantial amount of energy, balancing the high discharge rate with a respectable run time for all-day use.

  • Continuous Discharge Rating (CDR): 20A – Guarantees a safe and stable power output for most regulated mods running up to 70W per battery, preventing power sag under load.

  • Nominal Voltage: 3.6V (Standard) / 4.2V (Max) – Delivers consistent voltage to your device’s chip, ensuring accurate and stable wattage delivery throughout the discharge cycle.

  • Chemistry: Lithium Manganese Oxide (LiMn2O4) – This chemistry, commonly known as IMR, is inherently safer and more stable than other lithium ion types, making it the preferred choice for high-drain applications like vaping.

  • Format: Flat Top – Ensures the broadest possible compatibility with regulated mod contact pins and prevents accidental short circuits that can occur with button top batteries in vaping devices.

  • Internal Resistance: Low (typically below 20mΩ) – Minimizes heat generation during use and allows for more efficient power transfer, directly translating to less wasted energy and cooler operation.
