Samsung 25R Battery Overview

The Samsung 25R is a staple for both regulated and mechanical box mod users due to its performance and reliability. This cell provides a stable 20A continuous discharge current (CDR) paired with a substantial 2500mAh capacity. This balance is essential, ensuring sustained power delivery without premature voltage sag, which is often observed in lower-quality cells when drawing high currents.

Independent testing confirms that the 25R maintains favorable operating temperatures, consistently running cooler under load compared to many cells in its class that share a similar amperage rating. This results in improved cell longevity and increased user safety. While other 18650 cells may compete on capacity, the 25R often surpasses them by offering superior terminal voltage retention and usable capacity when operating at or near the 20A limit, making it a highly reliable and versatile choice for advanced vaping setups.
